Book Description
This book presents current research into the catalytic combustion of methane using perovskite-type oxides (ABO3). Catalytic combustion has been developed as a method of promoting efficient combustion with minimum pollutant formation as compared to conventional catalytic combustion. Recent theoretical and experimental studies have recommended that noble metals supported on (ABO3) with well-ordered porous networks show promising redox properties. Three-dimensionally ordered macroporous (3DOM) materials with interpenetrated and regular mesoporous systems have recently triggered enormous research activity due to their high surface areas, large pore volumes, uniform pore sizes, low cost, environmental benignity, and good chemical stability. These are all highly relevant in terms of the utilization of natural gas in light of recent catalytic innovations and technological advances. The book is of interest to all researchers active in utilization of natural gas with novel catalysts. The research covered comes from the most important industries and research centers in the field. The book serves not only as a text for researcher into catalytic combustion of methane, 3DOM perovskite mixed oxide, but also explores the field of green technologies by experts in academia and industry. This book will appeal to those interested in research on the environmental impact of combustion, materials and catalysis.

Book Description
ABSTRACT: A study of methane is conducted on the conditions of premixed lean methane air mixtures with platinum surface as a catalyst in one dimensional stagnation flow in steady state to understand enhancement of heat transfer under a new surface mechanism of methane oxidation. Premixed methane/air mixtures flowing onto platinum surface of various surface temperatures are simulated. Enhancement of heat transfer mechanism of catalytic methane oxidation is modeled based on GRI30 mechanism for gas reactions and Deutschmann mechanism for surface reactions. In the proposed surface mechanism, it is assumed that activated H2O and CO2 desorbs directly from platinum surface without elementary surface reaction and that activated H2O and CO2 are dissociated or deactivated by third body reactions. Thus, three elementary surface reactions are replaced in Deutschmann mechanism and four elementary reactions are added in GRI30 mechanism. Deutschmann mechanism and new catalytic methane mechanism are simulated and heat flux to non-reaction flow is calculated to see how much heat is required to maintain a given surface temperature. By comparing to conventional catalytic methane combustion, new mechanism shows different phenomena in ignition temperature, fuel consumption at each surface temperature, most importantly, heat transfer to non-reacting flow where there is no reactions due to enhancement of heat transfer by adsorption and desorption. In addition, heat transfer to non-reacting flow and enhancement of heat transfer are different with different rates of dissociation and deactivation reactions. Because of insufficient information about heat transfer to non-reacting flow, more research on enhancement of heat transfer is required to prove this mechanism.
