<p>This invention relates generally to the conversion of a lower molecular weight alkane to more valuable, heavier hydrocarbons,and more particularly concerns an aforesaid conversion which comprises the oxidative coupling of the alkane and the oxidative coupling catalyst employed therein. The specification discloses an improved oxidative coupling catalyst comprising a reducible compound of lead, antimony, vanadium, tin, bismuth, cadmium, indium, manganese or thallium or a mixture thereof and a support comprising silica having a surface area less than about 175 m2/gm, wherein the reducible compound is at a level of from about 2 to about 50 weight percent, calcul? the oxide of the reducible metal and based on? of the catalyst. The present invention is also an improved method for converting at least one feedstock alkane containing from 1 to 3 carbon atoms to more valuable, higher molecular weight hydrocarbons, comprising contacting the feedstock alkane with an oxygencontaining gas in a reactor in the presence of the aforesaid oxidative coupling catalyst at a temperature in the range of from about 600.degree.C to about 1000.degree.C.</p> |
