Download or read book Chemical Looping Partial Oxidation Process for Syngas Production written by Dikai Xu and published by . This book was released on 2017 with total page 155 pages. Available in PDF, EPUB and Kindle. Book excerpt: The chemical looping partial oxidation process is developed for the efficient conversion of gaseous and solid fuels into syngas via partial oxidation. The chemical looping partial oxidation process converts the fuels into high purity syngas with flexible H2:CO ratio that is suitable for downstream fuel or chemical synthesis. In the chemical looping partial oxidation process, the fuels are partially oxidized in the reducer reactor by the oxygen carrier to generate high purity syngas. The reduced oxygen carrier is regenerated in a fluidized bed combustor via the oxidation reaction with air. Compared to the conventional syngas generation processes, the chemical looping partial oxidation process eliminates the need for additional steam or molecular oxygen from an air separation unit (ASU), resulting in an increased cold gas efficiency and decreased fuel consumption. The chemical looping partial oxidation process features the combination of an iron-titanium composite metal oxide (ITCMO) oxygen carrier and a co-current gas-solid moving bed reducer reactor. The ITCMO oxygen carrier is selected for the chemical looping partial oxidation process due to its desired thermodynamic and kinetic properties. Theoretical analysis aided by a modified Ellingham Diagram illustrates that syngas production is thermodynamically favored in the presence of ITCMO oxygen carrier. The co-current moving bed reducer design provides a desirable gas-solid contacting pattern that minimizes carbon deposition while maximizing the syngas yield. Experimental studies in a fixed bed reactor and a bench scale reactor successfully demonstrate the production of high purity syngas from methane and biomass with the combination of moving bed reducer and ITCMO oxygen carrier. Further scale-up of the chemical looping partial oxidation process is demonstrated in an integrated sub-pilot scale reactor system using non-mechanical gas sealing and solid circulation devices. A dynamic modeling scheme is developed for studying the transient behavior and the control of the chemical looping system. A hierarchical control system based on sliding mode control concept is developed for the chemical looping technologies to simplify process operation.

This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Chemical looping partial oxidation is a process technology with the potential to enable clean, sustainable, and cost-effective valorization of hydrocarbon feedstocks to an array of chemical products. In the process scheme, the partial oxidation reaction is partitioned into separate reduction and oxidation reactions facilitated by an oxygen carrying chemical intermediate, referred to here as an oxygen carrier. By utilizing lattice oxygen donation from a metal oxide oxygen carrier in lieu of molecular oxygen, the hydrocarbon fuel can be efficiently converted to high purity syngas. The benefits and impacts of improving the efficiency of syngas generation are propagated through to downstream fuel and chemical synthesis processes. In this study, the chemical looping partial oxidation process for the thermochemical conversion of methane to syngas is investigated at the sub-pilot scale. Performance of the process and identification of viable operating conditions based on thermodynamic criteria is explored through process simulation. The design, construction, commissioning, and operation of a 15 kWth sub-pilot is detailed. In the unit, methane conversion of 99.64% and syngas purity of 97.13% are obtained with a product H2/CO ratio of 1.96. Co-reforming of methane with steam and CO2 is demonstrated, where net CO2 utilization is exhibited and flexible product H2/CO ratio of between 1.19 to 2.50 with high syngas purity is achieved. Finally, considerations for the design of the reactors during scale-up is discussed. The partial oxidation of biomass feedstocks towards the production of liquid fuels is investigated. Gasification of woody biomass and corncob biomass is studied at the sub-pilot scale where 89% carbon conversion and H2/CO ratio between 0.87 to 1.88 is demonstrated. Steam is shown to assist in the conversion of char in the moving bed reducer and suggestions toward commercial design are given. Adiabatic process simulation of the integration of the biomass to syngas process with the Fischer-Tropsch synthesis is investigated and it is shown that the chemical looping process can lead to 13.9% feedstock reduction and 5.7% increase in the lower heating value thermal efficiency relative to a competing gasification process. Finally, application electrical capacitance volume tomography is developed as a measurement technique to monitor and study the multiphase flow dynamics of the chemical looping process: critical to its scale-up and commercialization. A sensitivity gradient-based velocity profiling method is developed and applied to a gas-solid fluidized bed. The velocity profiles are validated against the cross-correlation technique and expected fluidized bed phenomena and breakdown of the method when tracking large objects is revealed and discussed.

This book was released on 2005-06-01 with total page 464 pages. Available in PDF, EPUB and Kindle. Book excerpt: Energy and feedstock materials for the chemical industry are in increasing demand and, with constraints related to the availability and use of oil, the energy and chemical industry is undergoing considerable changes. In recent years, major restructuring has occurred in the oil, petrochemical, and chemical industry, with increasing attention devoted to the use of natural gas, methane in particular, as a chemical feedstock rather than just as a fuel. The conversion of remote natural gas into liquid fuels or other transportable chemicals is a challenge to industrial catalysis. Few processes exist so far with the major ones involving the conversion of natural gas to synthesis gas by steam reforming, CO2 reforming, or partial oxidation, followed by the syntheses of methanol, hydrocarbons (Fischer-Tropsch synthesis), or ammonia. In this book, a comprehensive overview of the field of processing natural gas is given, through a series of chapters written by leading scientists and engineers in the field. New developments are discussed and current work relevant to the area is shown by a series of recent works by researchers working in this and related fields.

Download or read book Hydrogen Technology written by Aline Léon and published by Springer Science & Business Media. This book was released on 2008-07-18 with total page 680 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aline Leon ́ In the last years, public attention was increasingly shifted by the media and world governmentsto the conceptsof saving energy,reducingpollution,protectingthe - vironment, and developing long-term energy supply solutions. In parallel, research funding relating to alternative fuels and energy carriers is increasing on both - tional and international levels. Why has future energy supply become such a matter of concern? The reasons are the problems created by the world’s current energy supply s- tem which is mainly based on fossil fuels. In fact, the energystored in hydrocarb- based solid, liquid, and gaseous fuels was, is, and will be widely consumed for internal combustion engine-based transportation, for electricity and heat generation in residential and industrial sectors, and for the production of fertilizers in agric- ture, as it is convenient, abundant, and cheap. However, such a widespread use of fossil fuels by a constantly growing world population (from 2. 3 billion in 1939 to 6. 5 billion in 2006) gives rise to the two problems of oil supply and environmental degradation. The problemrelated to oil supply is caused by the fact that fossil fuels are not - newable primary energy sources: This means that since the rst barrel of petroleum has been pumped out from the ground, we have been exhausting a heritage given by nature.

This book was released on 2011-02-14 with total page 353 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents the current carbonaceous fuel conversion technologies based on chemical looping concepts in the context of traditional or conventional technologies. The key features of the chemical looping processes, their ability to generate a sequestration-ready CO2 stream, are thoroughly discussed. Chapter 2 is devoted entirely to the performance of particles in chemical looping technology and covers the subjects of solid particle design, synthesis, properties, and reactive characteristics. The looping processes can be applied for combustion and/or gasification of carbon-based material such as coal, natural gas, petroleum coke, and biomass directly or indirectly for steam, syngas, hydrogen, chemicals, electricity, and liquid fuels production. Details of the energy conversion efficiency and the economics of these looping processes for combustion and gasification applications in contrast to those of the conventional processes are given in Chapters 3, 4, and 5.Finally, Chapter 6 presents additional chemical looping applications that are potentially beneficial, including those for H2 storage and onboard H2 production, CO2 capture in combustion flue gas, power generation using fuel cell, steam-methane reforming, tar sand digestion, and chemicals and liquid fuel production. A CD is appended to this book that contains the chemical looping simulation files and the simulation results based on the ASPEN Plus software for such reactors as gasifier, reducer, oxidizer and combustor, and for such processes as conventional gasification processes, Syngas Chemical Looping Process, Calcium Looping Process, and Carbonation-Calcination Reaction (CCR) Process.
