Book excerpt: Most of the papers contained in this volume are based on pres entations made at the symposium on Catalytic Conversions of Synthesis Gas and Alcohols to Chemicals, which was held at the 17th Middle At lantic Regional Meeting of the American Chemical Society, April 6-8, 1983, in the setting of the Pocono Hershey Resort, White Haven, PA. I thank Dr. Ned D. Heindel, General Chairman, and Dr. Natalie Foster, Program Chairman, both of Lehigh University, for the invitation to organize the symposium. Financial support was received from Air Products and Chemicals, Inc. for the organization of the symposium, and acknowledgement is made to Air Products and Chemicals, Inc. and to the Donors of the Petroleum Research Fund, administered by the American Chemical Society, for partial support of the conduct of the symposium. The theme of this volume is the recent progress made in devel oping and understanding viable catalytic syntheses of chemicals di rectly from synthesis gas (CO + H2) or indirectly via alcohols. An aim of the symposium and of this volume is to provide a meaningful blend of applied and basic science and of the chemistry and engineer ing of processes that are, or hold promise to be, economically and industrially feasible. The topics demonstrate the increasing impor tance of synthesis gas as a versatile feedstock and emphasize the central role that alcohols, such as methanol, can playas chemical intermediates.

Available in PDF, EPUB and Kindle. Book excerpt: The origins of the petrochemical industry can be traced back to the 1920s when simple organic chemicals such as ethanol and isopropanol were first prepared on an industrial scale from by-products (ethylene and propylene) of oil refining. This oil-based petrochemical industry, with lower olefms and aromatics as the key building blocks, rapidly developed into the enormous industry it is today. A multitude of products that are indispensible to modern day society, from plastics to pharmaceuticals, are derived from oil and natural gas-based hydro carbons. The industry had its heyday in the '50s and '60s when predictions of future growth rates tended to be exponential curves. However, two developments that took place in the early '70s disturbed this simplistic and optimistic view of the future. Firstly, the publication of the report for the Cub of Rome on the 'Limits to Growth' emphasized the finite nature of non-renewable fossil fuel resources. Secondly, the Oil Crisis of 1973 emphasized the vulnerability of an energy and chemicals industry that is based largely on a single raw material.

This book was released on 2021 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: In attempts to address the threats of climate change, countries are making efforts to mitigate their emissions of greenhouse gases like carbon dioxide (CO2). The transition from economies driven by energy and chemicals derived from fossil fuel feedstocks to cleaner alternative fuels and technologies are met with great challenges. In the field of fuel and chemical production specifically, the transformation of carbon monoxide (CO) and CO2, produced through alternative technologies, to value added chemical products require catalysts that are active, selective, and stable. Current research efforts have focused on heavy characterization of catalysts in attempts of establishing a structure-activity correlation to help design and engineer the catalyst of the future. This thesis will focus on the design and characterization of two supported transition metal phosphide (TMP) catalysts, molybdenum phosphide (MoP) and ruthenium phosphide (RuP), and a bimetallic nickel iron (NiFe) catalyst. The first TMP, MoP, was specifically designed and optimized for the higher alcohol synthesis (HAS) reaction from synthesis gas (syngas) (CO/H2). Higher alcohols are defined as an alcohol group containing two or more carbon atoms., like ethanol. Through a systematic design approach, the optimal amount of potassium (K) promoter, P and Mo was determined and synthesized on three different supports: amorphous silica (SiO2), ordered silica (SBA-15), and mesoporous carbon (C). The different combinations led to contrasting catalytic performance with respect the HAS activity. The second TMP, RuP, was designed and optimized for the methanol synthesis (MS) reaction. Ru catalysts are known as Fischer-Tropsch synthesis (FTS) catalysts as they selectively produce hydrocarbons. This study was able to change the intrinsic catalytic nature of Ru through addition of P. Catalytic results showed that the presence of P transformed the Ru FTS catalyst to a MS catalyst. The NiFe catalyst was tested for the ethane dehydrogenation reaction, in which the essential feedstock chemical ethylene is produced. This catalyst was tested for direct ethane dehydrogenation, in which only ethane is fed to the reactor along with H2 to mitigate coking, and oxidative ethane dehydrogenation, where CO2 is fed to promote the reacting and mitigate coking. The catalysts were also synthesized on two different supports, SiO2 and C, to quantify support effects. The overall goal of these studies was to determine the influence that addition of promoters, like K, phosphides, and secondary metals have on catalytic properties and how we might use that to design catalysts with improved activity, selectivity, and stability.

Download or read book Gaseous Carbon Waste Streams Utilization written by National Academies of Sciences, Engineering, and Medicine and published by National Academies Press. This book was released on 2019-02-22 with total page 257 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the quest to mitigate the buildup of greenhouse gases in Earth's atmosphere, researchers and policymakers have increasingly turned their attention to techniques for capturing greenhouse gases such as carbon dioxide and methane, either from the locations where they are emitted or directly from the atmosphere. Once captured, these gases can be stored or put to use. While both carbon storage and carbon utilization have costs, utilization offers the opportunity to recover some of the cost and even generate economic value. While current carbon utilization projects operate at a relatively small scale, some estimates suggest the market for waste carbon-derived products could grow to hundreds of billions of dollars within a few decades, utilizing several thousand teragrams of waste carbon gases per year. Gaseous Carbon Waste Streams Utilization: Status and Research Needs assesses research and development needs relevant to understanding and improving the commercial viability of waste carbon utilization technologies and defines a research agenda to address key challenges. The report is intended to help inform decision making surrounding the development and deployment of waste carbon utilization technologies under a variety of circumstances, whether motivated by a goal to improve processes for making carbon-based products, to generate revenue, or to achieve environmental goals.

This book was released on 2016-12-10 with total page 137 pages. Available in PDF, EPUB and Kindle. Book excerpt: A decade ago, the U.S. chemical industry was in decline. Of the more than 40 chemical manufacturing plants being built worldwide in the mid-2000s with more than $1 billion in capitalization, none were under construction in the United States. Today, as a result of abundant domestic supplies of affordable natural gas and natural gas liquids resulting from the dramatic rise in shale gas production, the U.S. chemical industry has gone from the world's highest-cost producer in 2005 to among the lowest-cost producers today. The low cost and increased supply of natural gas and natural gas liquids provides an opportunity to discover and develop new catalysts and processes to enable the direct conversion of natural gas and natural gas liquids into value-added chemicals with a lower carbon footprint. The economic implications of developing advanced technologies to utilize and process natural gas and natural gas liquids for chemical production could be significant, as commodity, intermediate, and fine chemicals represent a higher-economic-value use of shale gas compared with its use as a fuel. To better understand the opportunities for catalysis research in an era of shifting feedstocks for chemical production and to identify the gaps in the current research portfolio, the National Academies of Sciences, Engineering, and Medicine conducted an interactive, multidisciplinary workshop in March 2016. The goal of this workshop was to identify advances in catalysis that can enable the United States to fully realize the potential of the shale gas revolution for the U.S. chemical industry and, as a result, to help target the efforts of U.S. researchers and funding agencies on those areas of science and technology development that are most critical to achieving these advances. This publication summarizes the presentations and discussions from the workshop.
Download or read book Catalysis in Petrochemical Processes written by M.S. Matar and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 209 pages. Available in PDF, EPUB and Kindle. Book excerpt: The field of petrochemicals started some years ago with the simple addition reaction of water to propylene for the production of isopropyl alcohol. Currently, the petrochemical industry has become a multi-billion dollar enterprise which encompasses a wide field of chemical products. Almost all the basic organic reactions such as hydrogenation, alkylation, substitution, polymerization, etc. are utilized for the production of these chemicals. It may not, however, have been possible to establish this huge industry without the use of different catalysts. In other words, the great advancements in the catalytic area have supported the vast developments in the petrochemical field. In this book, we have adopted the idea of discussing the petrochemical industry from the point of view of reactants' activities and susceptibilities toward different catalysts. The book is thus classified according to the reaction type. This will eriable students and other users of the book to base their understanding of the petrochemical field on the fundamental principles learned in chemistry. How ever, the first chapter is aimed at establishing some basic facts on the petro chemical industry and its major uses. It discusses, without going into details, the raw materials used, the intermediates and the downstream products. The next eight chapters discuss in some detail the main reactions and the catalysts used for the production of chemicals and polymers from petroleum. The last chapter is devoted to a discussion of some of the practical techniques used in the catalytic field.
Download or read book Catalytic Conversion of Syngas to Higher Alcohols Over Cu Fe Based Catalysts written by Yongwu Lu and published by . This book was released on 2014 with total page 159 pages. Available in PDF, EPUB and Kindle. Book excerpt: Higher alcohol synthesis (HAS) from syngas or biomass-derived syngas is an important process for the production of oxygenate fuels, fuel additives and other intermediates for value-added chemical feedstock to produce medicine, cosmetics, lubricants, detergents, and polyesters. Chapter I reviews biomass to liquid fuels technology, higher alcohols being used as alternative fuels and fuel additives, the historical perspective and commercial status of higher alcohols, the catalyst system and the reaction mechanism for HAS from syngas. Chapter II discusses the Zn-Mn promoted Cu-Fe based catalyst that was synthesized by the co-precipitation method. The reaction temperature has been tested to study the influence on the catalytic performance. The maximal CO conversion rate was 72%, and the yield of alcohol and hydrocarbon was also very high. Cu was the active site for alcohol synthesis, iron carbide was the active site for olefin and paraffin synthesis. The reaction mechanism of HAS from syngas over Zn-Mn promoted Cu-Fe based catalyst was proposed. Chapter III documents the three-dimensionally ordered macroporous (3DOM) Cu-Fe catalyst developed using a glyoxylate route colloidal crystal template method. The high intrinsic activity was ascribed to three factors. First, the unique ordered structure has a large pore size and interconnected macroporous tunnels of the catalyst with a large accessible surface area to improve the catalytic activity. Second, a high density of uniformly distributed defective Cu0 and Fe5C2 nanoparticles derived from the glyoxylate route helps to provide abundant, active, and stable dual sites. Third, atomic steps on the Cu surface, induced by planar defects and lattice strain, serve as high-activity oxygenation sites. Active Fe5C2 chain-growth sites intimately surround the defective and strained form of the Cu surface, which results in a synergetic effect between the active and stable Cu--FexCy dual site for HAS. In Chapter IV, in situ ambient pressure x-ray photoelectron spectroscopy and in situ synchrotron powder diffraction were applied to identify the active site of 3DOM Cu-Fe catalyst for HAS. The results show that after syngas pretreatment of the 3DOM Cu-Fe catalyst, Cu0 is the active oxygenation site for alcohol synthesis, and Fe5C2 is the active site for carbon chain growth.

Download or read book Natural Gas Conversion V written by A. Parmaliana and published by Elsevier. This book was released on 1998-09-17 with total page 1005 pages. Available in PDF, EPUB and Kindle. Book excerpt: On January 1988, the ascertained and economically accessible reserves of Natural Gas (NG) amounted to over 144,000 billion cubic meters worldwide, corresponding to 124 billion tons of oil equivalents (comparable with the liquid oil reserves, which are estimated to be 138 billion TOE). It is hypothesized that the volume of NG reserve will continue to grow at the same rate of the last decade. Forecasts on production indicate a potential increase from about 2,000 billion cubic meters in 1990 to not more than 3,300 billion cubic meters in 2010, even in a high economic development scenario. NG consumption represents only one half of oil: 1.9 billion TOE/y as compared to 3.5 of oil. Consequently, in the future gas will exceed oil as a carbon atom source. In the future the potential for getting energetic vectors or petrochemicals from NG will continue to grow. The topics covered in Natural Gas Conversion V reflect the large global R&D effort to look for new and economic ways of NG exploitation. These range from the direct conversion of methane and light paraffins to the indirect conversion through synthesis gas to fuels and chemicals. Particularly underlined and visible are the technologies already commercially viable. These proceedings prove that mature and technologically feasible processes for natural gas conversion are already available and that new and improved catalytic approaches are currently developing, the validity and feasibility of which will soon be documented. This is an exciting area of modern catalysis, which will certainly open novel and rewarding perspectives for the chemical, energy and petrochemical industries.

Available in PDF, EPUB and Kindle. Book excerpt: This book provides a general overview of syngas technologies as well as an in-depth analysis of the steam reforming process. Syngas is a mixture of hydrogen and carbon oxides which can be made from hydrocarbons, coal and biomass. It is an important intermediate in the chemical industry for manufacture of ammonia, methanol and other petrochemicals as well as hydrogen for refineries and fuel cells. Syngas is playing a growing role in the energy sector, because it can be converted into a number of important energy carriers and fuels. Syngas catalysis creates new options and flexibility in the complex energy network. The steam reforming process is the main technology today for manufacture of syngas. It is a complex intern-mingling of catalysis and heat transfer with restrictions caused by secondary phenomena such as carbon formation. Many of the principles are applicable for other gasification technologies of growing importance. Concepts of Syngas Preparation aims to provide a comprehensive introduction to this complex field of growing importance and gives a detailed analysis of the catalyst and process problems. This book also serves as an important link between science and industry by illustrating how the basic principles can be applied to solve design issues and operational problems./a

This book was released on 2012-12-06 with total page 239 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the oil embargo, in the winter 1973174, parts of Western Europe present ed an almost war-like aspect on Saturdays and Sundays: no traffic on the high ways, no crowds at ski resorts and other weekend entertainment places, no gaso line at the pumps. Living and teaching then in that part of the world, and discussing the situa tion with our students, we came to the conclusion that it would be timely to col lect the fine chemistry already known at the time in the field of conversion of coal to gasoline and other chemicals, and by this way help to draw the attention to this important alternative to crude oil. The idea of this book was born. The energy shock of the early seventies has been healthy and of great conse quences in chemistry. Large amounts of research money have been put to work since, and our knowledge of the possibilities and limitations of coal-based chemistry has increased enormously. During several years it appeared inap propriate to write a monograph about a topic which was in the midst of such an impetuous development. Nevertheless, we collected, and critically selected, the upcoming work as it appeared in the literature, and also tried to provide some modest input ourselves. Now, ten years later, the situation seems to be settled to a certain degree.
