Plasma Catalysis
Author: Annemie Bogaerts
Publisher: MDPI
ISBN: 3038977500
Category : Technology & Engineering
Languages : en
Pages : 248
Book Description
Plasma catalysis is gaining increasing interest for various gas conversion applications, such as CO2 conversion into value-added chemicals and fuels, N2 fixation for the synthesis of NH3 or NOx, methane conversion into higher hydrocarbons or oxygenates. It is also widely used for air pollution control (e.g., VOC remediation). Plasma catalysis allows thermodynamically difficult reactions to proceed at ambient pressure and temperature, due to activation of the gas molecules by energetic electrons created in the plasma. However, plasma is very reactive but not selective, and thus a catalyst is needed to improve the selectivity. In spite of the growing interest in plasma catalysis, the underlying mechanisms of the (possible) synergy between plasma and catalyst are not yet fully understood. Indeed, plasma catalysis is quite complicated, as the plasma will affect the catalyst and vice versa. Moreover, due to the reactive plasma environment, the most suitable catalysts will probably be different from thermal catalysts. More research is needed to better understand the plasma–catalyst interactions, in order to further improve the applications.

Handbook Of Advanced Methods And Processes In Oxidation Catalysis: From Laboratory To Industry
Author: Daniel Duprez
Publisher: World Scientific
ISBN: 1783263342
Category : Science
Languages : en
Pages : 1035
Book Description
This book offers a comprehensive overview of the most recent developments in both total oxidation and combustion and also in selective oxidation. For each topic, fundamental aspects are paralleled with industrial applications. The book covers oxidation catalysis, one of the major areas of industrial chemistry, outlining recent achievements, current challenges and future opportunities. One distinguishing feature of the book is the selection of arguments which are emblematic of current trends in the chemical industry, such as miniaturization, use of alternative, greener oxidants, and innovative systems for pollutant abatement. Topics outlined are described in terms of both catalyst and reaction chemistry, and also reactor and process technology.

Reaction Mechanisms for Catalytic Partial Oxidation Systems

Languages : en
Pages : 395
Book Description
(Cont.) Formulas for activation energies have been derived for generic reaction types, including simple adsorption, dissociation-recombination, and disproportionation reactions. Basis of the correction approach is the Bond Additivity Correction (BAC) procedures, which apply atomic, molecular and bond- wise modifications to enthalpies of molecules predicted by G3B3 and G3MP2B3 composite quantum chemistry methods available in Gaussian® suite of programs. The new procedures have improved the accuracy of thermochemical properties for open and closed shell molecules containing various chemical moieties, multireference configurations, isomers and degrees of saturation involving elements from first 3 rows of the periodic table. The detailed mechanism explains the selectivity to ethylene oxide based on the parallel branching reactions of surface oxametallacycle to epoxide and acetaldehyde. Using Decomposition Tree Approach, surface reactions and species have been generated to develop a comprehensive mechanism for epoxidation. As a result of these developments in the thesis, chemisorption enthalpies can now be estimated within 3 kcal/mol of experimental values for transition metal catalysts and enthalpies predicted by G3B3 and G3MP2B3 Gaussian methods can be corrected within 0.5 kcal/mol. Examples of heterogeneous reaction systems involving silver-catalyzed ethylene epoxidation demonstrate the effectiveness of the methodologies developed in this work.

Languages : en
Pages : 423
Book Description
This volume contains papers and short communications presented at the 12th Canadian Symposium on Catalysis. The aim of the meeting was to present an update on new and established areas of catalysis research being performed in industry, government and university laboratories. Topics covered relate mainly to resource processing, such as heavy oil and natural gas upgrading, and to environmental issues. Approximately half the papers are included in sections on hydrogenation, carbon-carbon bond formation and environmental issues. The remaining papers cover general topics and homogeneous reactions. Examples include studies of hydroprocessing catalysts, carbon-carbon bond formation via methane oxidative coupling and dimerization of olefins, homogeneous catalysts in polymerization and dimerization reactions, performance of pillared clays, metal-oxygen cluster compounds, zeolites and catalysts prepared by metal oxide vapour synthesis. Studies that address the environmental issues include wet-air oxidation, catalytic elimination of organics, oxidation reactions and catalyst regeneration. The book provides practitioners of catalysis with an update on a wide number of topics and will be particularly useful to those interested in an overview of current catalysis research activities. Specialists in the areas of hydrogenation, carbon-carbon bond formation, homogeneous catalysis and environmental issues will also find a valuable set of new data and interesting discussions on these topics.
