Kinetics of methanation of carbon monoxide and carbon dioxide

Abstract

The kinetics of reaction of carbon monoxide and carbon dioxide with hydrogen in a nickel catalyst tube wall reactor were investigated experimentally and the reaction mechanisms were clarified. The observed rate laws were for carbon dioxide at low partial pressure. These reaction rate laws were derived theoretically from the proposed reaction mechanism. For a mixture of carbon monoxide and carbon dioxide the kinetics of the reaction proved to be well accounted for by the same reaction mechanism. © 1984, The Society of Chemical Engineers, Japan.
