Transformations of ethane and ethylene with methane on a resistive fechral catalyst in the presence of hydrogen

Abstract

Transformations of methane-ethane, methane-ethylene, hydrogen-ethane and hydrogen-ethylene mixtures on an electrically heated resistive fechral catalyst were studied. During the transformations, the catalyst surface becomes covered with graphitic carbon deposits, which exertan additional catalytic action leading to the formation of C3 and C4 hydrocarbons. The formation of the indicated hydrocarbons proceeds most likely with the involvement of ethylene produced from ethane. The presence of hydrogen suppresses coking of the catalyst surface and decreases the yields of C3 and C4 hydrocarbons.
