Abstract: A methed for converting a feedstock alkane containing from 1 to 3 carbon atoms to a higher molecular weight hydrocarbon comprising contacting a feedstock with an oxygen-containing gas in the presence of a catalytic composition is disclosed. The catalytic composition includes a Group IA metal, a Group IIA metal and a third component, the precursor of which is a sol such as an aqueous suspension of a metal such as aluminum, silicon, titanium, zinc, zirconium, cadmium or tin with which the other components of the composition are throughly dispersed.

Abstract: A process for the halogen-assisted conversion of lower alkanes to higher molecular weight hydrocarbons is provided. A first reaction mixture including lower alkanes, a hydrogen halide and an oxygen-containing gas are contacted with a catalytic composition of crystalline copper aluminum borate at appropriate reaction conditions to form an intermediate composition including halogenated alkanes. The halogenated alkanes are subsequently contacted with a catalytic composition of a pentasil molecular sieve material under appropriate reaction conditions to form a product mixture including hydrocarbons having molecular weights greater than the lower alkanes.
