Abstract
A method for preparing ethane and ethylene by reacting methane or a methane-containing natural gas in the presence of oxygen or an oxygen-containing gas, i.e., by partially oxidizing, at a temperature of 500.degree. through 1000.degree. C. using shellfishes or shells as a catalyst is disclosed. The oxidation coupling reaction of methane is controlled so as to remarkably increase the conversion ratio of methane and the selectivity of C.sub.2.sup.+ compounds. The waste matter abundantly released from food industries as well as easily accessible natural resources is used as a raw material of a catalyst for the reaction. The present method is extremely useful from the viewpoint of the recycling of waste as well.
