Chemical looping systems for fossil energy conversions 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.
