Rising oil costs have stimulated significant interest in the Fischer-Tropsch synthesis (FTS) as a method for producing a synthetic petroleum substitute. Drawn from the proceedings at a symposium held during the 236th meeting of the American Chemical Society in Philadelphia in August 2008, Advances in Fischer-Tropsch Synthesis, Catalysts, and Catalysis explores the recent developments in Fischer-Tropsch technology, which holds great promise in the area of renewable resources.Expert contributors explore a range of issuesThe book focuses on three main themes: catalyst preparation and activation, reaction mechanism, and process-related topics. A panel of expert contributors discusses synthesis of catalysts, carbon nanomaterials, nitric oxide calcinations, the influence of carbon, catalytic performance issues, chelating agents, and Cu and alkali promoters. They also explore Co/silica catalysts, thermodynamic control, the Two Alpha model, co-feeding experiments, internal diffusion limitations, Fe-LTFT selectivity, and the effect of co-fed water. Lastly, the book examines cross-flow filtration, kinetic studies, reduction of CO2 emissions, syncrude, and low-temperature water-gas shift.Attaining the maximum catalytic activity and catalyst lifeThe themes explored in the book demonstrate that while the Fischer-Tropsch synthesis (FTS) has advanced in maturity, many issues remain concerning the preparation of increasingly active catalysts and the method of activation to attain the maximum catalytic activity and catalyst life. The book includes coverage of the structural features, their changes, and the application of increasingly sophisticated characterization techniques, shedding light on the reaction mechanism and providing a glimpse into the processes and reaction rates under realistic commercial process conditions.

With petroleum prices spiraling upward, making synthetic fuels—or "synfuels"—from coal, natural gas, and biomass has become more economically competitive. Advanced energy companies now focus exclusively on alternative fuels, and many oil companies have programs dedicated to developing synthetic fuels. The Fischer-Tropsch process, which uses a collection of chemical reactions to convert mixtures of carbon monoxide and hydrogen into liquid hydrocarbons, is the studied method of choice for producing synthetic petroleum substitutes.Fischer-Tropsch Synthesis, Catalysts, and Catalysis: Advances and Applications began at a symposium held during the 248th American Chemical Society meeting, where high attendance demonstrated great interest in Fischer-Tropsch synthesis. The lively discussions that occurred led to the creation of this carefully constructed reference work. The contributors here have expanded and reorganized their presentations from the conference into thorough chapters that reflect the four key subject areas that dominated the presentations:Catalyst preparation and activationCatalyst activity and reaction mechanismsCatalyst characterization and related reactionsTopics concerning commercializing the Fischer-Tropsch processWhile describing advances and exploring the potential of the Fischer-Tropsch process in the future of synthetic fuels, the research also demonstrates that several issues remain in producing increasingly active catalysts and more efficient reactor design.Covering recent developments in Fischer-Tropsch technology for renewable resources and green energy, this book is a significant contribution for researchers and practitioners concerned with the production of synthetic fuels. It explores new and sophisticated techniques while providing a look at the application of these advances to commercial processing conditions.

This volume looks at the recent progress of this technology as reported in the 21 papers presented during the 219th National Meeting of the ACS in New York, September 5-11, 2003.In addition, the volume focuses on the use of modern spectroscopic techniques for the generation of detailed structural analysis required for the advancement of the science of FCC design.Other chapters look at the use and importance of solid state nuclear magnetic resonance (NMR), microcalorimetry and atomic force microscopy (AFM) to the study of FCCs and discussing strategies to control pollutant emissions from a refinery FCCU and looking at advances in FCC preparation.

"Based on the American Chemical Society's Second Symposium on Advances in Hydrotreating Catalysts, held in Washington, D.C. Offers comprehensive coverage of the most recent progress in catalysis by transition metal sulfides for the creation of more environmentally safe catalysts and processes. Written by over 70 acclaimed experts from various fields."

Refiners’ efforts to conform to increasingly stringent laws and a preference for fuels derived from renewable sources have mandated changes in fluid cracking catalyst technology. Advances in Fluid Catalytic Cracking: Testing, Characterization, and Environmental Regulations explores recent advances and innovations in this important component of petroleum refining technology and evaluates how the industry has been changed by environmental regulations worldwide.Measurement, testing, and improvementModern spectroscopic techniques continue to be essential to the understanding of catalyst performance and feedstock properties. The book contains a detailed review of the use of adsorption microcalorimetry to measure acidity, acid site density, and the strength of the strongest acid sites in heterogenous catalysts. It also discusses the use of 1H-NMR to characterize the properties of a FCCU feedstock. In addition, the book dedicates several chapters to pilot plant testing of catalysts and nontraditional feedstocks, maximizing and improving LCO (heating oil) production and quality, and improving FCCU operations.Complying with the EPAThe EPA has identified the petroleum refining industry as a targeted enforcement area for the Clean Air Act (CAA) passed in 1970 and the CAA Amendments of 1990. The final chapters of the book examine the evolution of the EPA’s attempts to encourage the refining industry to enter into voluntary consent decrees to comply with the CAA and the 1990 amendments. The book describes consent decree negotiations as well as FCC emissions (SOx, NOx, CO, PM) reduction technologies through consent decree implementations.Containing contributions from a panel of worldwide experts, the book demonstrates how the global shift toward environmentalism has engineered significant changes in the petroleum refining industry at a critical level.
