Mechanistic and kinetic studies of the elementary processes in catalytic combustion of methane. Annual report Sep 81-Aug 82
This report describes the progress towards determining the kinetics and the mechanism in the catalytic oxidation of methane by studying the reaction of some postulated intermediates on a well-characterized surface. Current emphasis is on the intermediate methylene radical. Preparation of the precursor for methylene, diazomethane is briefly described. An initial result suggested that diazomethane on adsorption on platinum decomposed readily to gaseous nitrogen and an adsorbed carbonaceous species. On heating methane and ethylene are the major products in the absence of oxygen. In contrast, adsorbed ethylene does not undergo reaction before desorption. This evidence suggests that the decomposed product is the desired methylene radical.
