This book was released on 2011-05 with total page 412 pages. Available in PDF, EPUB and Kindle. Book excerpt: The global warming problem might be the greatest threat to the future of mankind, and scientists have concluded that Energy related activities are the main cause. Leaks in natural gas transmission facilities are the main sources of fugitive methane emissions which are difficult to mitigate. This book aims at evaluating the possibility of using catalytic reactor t for mitigation of fugitive methane emissions. The focus will be on natural gas compressor station which is a major single source of fugitive methane. Computer modelling of the flow patterns inside the building demonstrated the influence of ventilation openings, ambient temperature and leak location. For a typical building most methane emitted inside will exit through the ridge vent provided the main doors remain closed. When the extraction rate through the ridge vent is controlled, the methane concentration can satisfy the CFRR feed quality. The reactor performance was studied in detail. Two different types of catalysts were evaluated and also a number of parametric studies were conducted. Overall, the proposed technology offers promising results for methane emission abatement.

This book was released on 2014 with total page 233 pages. Available in PDF, EPUB and Kindle. Book excerpt: Green House Gases (GHG) contribution to global warming has led to extensive research into reduction of emission of the GHG. Transportation, as a main contributor to GHG, faces a major challenge in researching and developing of new technologies with the aim of reducing the carbon foot print. The use of alternative fuels with lower harmful emissions became obvious as a result of emission control regulations and climate change. Natural gas engines gained popularity due to their ability to burn the fuel almost completely, which recommends them as an environmentally friendly alternative to fossil fuels engines. However, the incomplete combustion of methane in natural gas engines will release methane and carbon monoxide into the atmosphere. The fugitive methane emission problem can be tackled by the development of performant catalytic converters. This project reports on catalytic activity and stability of three sets of catalyst. The first set, palladium only catalysts provided by 15, 80 and 150 g/ft3 loading, were designed for methane combustion but not necessarily for lean burn engines. The second set studied were 2 catalysts: Pt and Pt-Pd (4:1) catalyst, with a loading of 95 g/ft3. Their mainly intend was the use as diesel oxidation catalysts. The third set of catalytic converters was designed for use for lean burn gas engines. The catalysts studied were Pt-Pd (1:5) with a loading of 150 g/ft3, Pd 122 (122 g/ft3), Pd Rh (117.15:2.85) (loading 120 g/ft3) and PtPdRh (19:73:2.85) with a loading of 94.85 g/ft3. The influence of different pretreatments on the catalyst activity (i.e. de-greening temperature, reduction process) were studied through ignition-extinction experiments. The stability of the catalyst was investigated through thermal ageing experiments. The effect of water on the catalytic activity was investigated through hydro-thermal ageing experiments.

Available in PDF, EPUB and Kindle. Book excerpt: In a clear and concise manner, this book explains how to apply concepts in chemical reaction engineering and transport phenomena to the design of catalytic combustion systems. Although there are many textbooks on the subject of chemical reaction engineering, catalytic combustion is mentioned either only briefly or not at all. The authors have chosen three examples where catalytic combustion is utilized as a primary combustion process and natural gas is used as a fuel - stationary gas turbines, process fluid heaters, and radiant heaters; these cover much of the area where research is currently most active. In each of these there are clear environmental benefits to be gained illustrating catalytic combustion as a "cleaner primary combustion process" . The dominant heat transfer processes in each of the applications are different, as are the support systems, flow geometrics and operating conditions.

This book was released on 2015-04-30 with total page 123 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents current research into the catalytic combustion of methane using perovskite-type oxides (ABO3). Catalytic combustion has been developed as a method of promoting efficient combustion with minimum pollutant formation as compared to conventional catalytic combustion. Recent theoretical and experimental studies have recommended that noble metals supported on (ABO3) with well-ordered porous networks show promising redox properties. Three-dimensionally ordered macroporous (3DOM) materials with interpenetrated and regular mesoporous systems have recently triggered enormous research activity due to their high surface areas, large pore volumes, uniform pore sizes, low cost, environmental benignity, and good chemical stability. These are all highly relevant in terms of the utilization of natural gas in light of recent catalytic innovations and technological advances. The book is of interest to all researchers active in utilization of natural gas with novel catalysts. The research covered comes from the most important industries and research centers in the field. The book serves not only as a text for researcher into catalytic combustion of methane, 3DOM perovskite mixed oxide, but also explores the field of green technologies by experts in academia and industry. This book will appeal to those interested in research on the environmental impact of combustion, materials and catalysis.

This book was released on 2008 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: ABSTRACT: In recent years, catalytic combustion has been intensely researched for its ability to reduce NO[subscript x] emissions and the release of unburned hydrocarbons. One major point of interest is the use of catalytic reactors along with homogeneous combustors to create a hybrid combustor for power generation cycles. By using catalysis along with traditional homogeneous combustion, the same amount of energy can be released from hydrocarbon fuels at a temperature lower than the adiabatic flame temperature, which results in a reduction in the produced NO[subscript x] emissions. While studies on the activity of fuel lean catalytic reactors are well published, there have been few investigations for the fuel rich catalytic reactors. Another aspect of catalytic combustion which has little published research is the study of heat transfer effects initiated by a catalytically active surface. The focus of this research is to study and model the chemical kinetics for the fuel rich catalytic combustion of methane, hydrogen, and syngas as well as to investigate the effect of a catalytically active surface on the convective heat transfer coefficient of the catalyst surface.

This book was released on 2019 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Mixed metal oxides for catalytic methane combustion: This project explores the development of mixed metal oxides containing Pd for catalytic oxidation of low concentration CH4 for ventilation air methane (VAM) mitigation technologies targeted towards reducing green-house gas emissions from coal mines. The aim here is to reduce the loading of Pd in the catalytic materials by designing a bifunctional catalyst using a transition metal as the main component and Pd as a promoter. Using the bifunctional catalyst is not only expected to enhance the activity towards CH4 combustion but is also expected to increase the tolerance of the catalyst towards poisoning by water, thereby increasing the economic feasibility of this technology. The studies are designed to provide key insights into catalyst chemistry using in-situ characterization techniques that can be leveraged to increase the efficiency of lean methane combustion technologies.

Available in PDF, EPUB and Kindle. Book excerpt: Catalytic combustion is an efficient method to reduce pollutant emissions produced by a variety of fuels. In this thesis, the use of iron pentacarbonyl (Fe(CO)5) as a catalyst precursor in the combustion of natural gas is experimentally studied. The counter-flow diffusion flame burner is employed as the experimental apparatus. The products of combustion are analyzed by using a Gas Chromatograph (GC) to quantitate the effects of adding the catalyst. The experimental setup is such that a mixture of methane (CH4) and nitrogen (N2) is fed from the bottom burner while a mixture of oxygen (O2) and air is supplied from the top burner. The combustion of natural gas without catalyst is first characterized. The oxidizer and fuel flow parameters are set up so that a stable, flat blue flame is formed close to the centre plane between the two burners upon ignition. The experimental results agree with the literature data and the numerical predictions from CHEMKIN software. To investigate and evaluate the performance of iron-containing catalysts on emission reduction, a small amount of separated nitrogen flow is used to carry iron pentacarbonyl into the flame through the central port of the fuel-side burner. Catalytic combustion produces an orange flame. Compared with the non-catalytic combustion data, it is found that carbon monoxide (CO) and soot precursor acetylene (C2H2) are reduced by 80% to 95% when 7453ppm iron pentacarbonyl is added.
