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.

Book Description
Catalytic oxidation processes are bf central importance to a substantial part of large-scale chemical industry. Indeed, this area of industrial catalysis has an extremely long history which stretches back well into the last century. The development and growth of catalytic oxi dation processes for the manufacture of commodities such as sulfuric acid and nitric acid can be viewed as indicators for the growth of the early and middle years of the entire inorganic chemical industry, and in an analogous fashion the manufacture of products such as phthalic anhydride, maleic anhydride and ethylene oxide has been central to the development of an organic chemical industry. We should all be able" to learn from history, and present-day scientists and technologists will find considerable benefit in following the account of the historical development of catalytic oxidation processes presented in Chapter I by Drs. G. Chinchen, P. Davies and R. J. Sampson. Alkenes are important intermediates in many processes in organic chemical industry. Being mostly petroleum derived, the alkene availability pattern does not necessar ily match consumption requirements and an alkene inter conversion process such as metathesis is clearly of in dustrial importance. In fact alkene metathesis, in addi tion to its industrial significance, poses an interesting mechanistic problem. upon which considerable effort has been expended in recent years and which is now fairly well understood.

Book Description
This book brings together highlights of a theme which is growing in interest: the creation of a sustainable society using catalysis as the main tool. Catalysts play key roles in the production of clean fuels, the conversion of waste and green raw materials into energy, clean combustion engines including control of NOx and soot production and reduction of greenhouse gases, production of clean water and of polymers, as well as reduction from polymers to monomers. Catalysts are also of prime importance in the developing H2 and syngas production technology, aimed at producing clean fuels for the coming decades. And catalysts can be recycled.

Book Description
The utilization of carbon dioxide reforming of methane in a solar based Chemical Energy Transmission System (CETS) relies greatly upon the development of suitable catalysts for both the endothermic and exothermic reactions. Carbon dioxide reforming of methane produces hydrogen and carbon monoxide at a ratio of about one, thus requiring the methanation reaction on the other side of the closed loop CETS to utilize this feed. H2/CO ratios lower than three favor the formation of carbon with industrial methanation catalysts. Preliminary tests performed on methanation with rhodium and nickel catalysts produced two, 0.5% Rh/A12O3 and Ni/A12O3, for further study. Kinetic experiments were conducted in an isothermal continuous stirred tank reactor constructed of a copper alloy which prevented carbon formation on reactor parts. These experiments were performed on pelleted 0.5% Rh/A12O3 in the 400 to 500 C range and pelleted 70% Ni/A12O3 in the 300 to 500 C temperature range. In most experiments steam was added to the reactor feed to inhibit carbon formation. Keywords: Catalytic methanation, Methanation kinetics, Carbon monoxide, Hydrogen, Rhodium, Nickel, Theses. (MJM).

Book Description
The study of surfaces has experienced dramatic growth over the past decade. Now, the editors of the internationally celebrated series Advances in Chemical Physics have brought together in this self-contained, special topic volume contributions from leading researchers in the field treating some of the most crucial aspects of the experimental and theoretical study of surfaces. This work delves into such core issues as: * Kinetics and dynamics of hydrogen adsorption on silicon surfaces. * Potential energy surfaces of transition- metal-catalyzed chemical reactions. * High-resolution helium atom scattering as a proof of surface vibrations. * Ordering and phase transitions in adsorbed monolayers of diatomic molecules. * The influence of dimensionality on static and dynamic properties of a system. * New applications to fields as varied as catalysts and the passage of molecules through membranes. This valuable resource provides important insights into the current state of knowledge about surface properties. Prigogine and Rice's latest work will stimulate the imagination and motivate the exploration of other aspects of this fascinating subject.
