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.

Catalyst for lower alkane conversion

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.

Halogen-assisted conversion of lower alkanes

A method for halogenating hydrocarbons wherein a reaction mixture including a hydrocarbon-containing feed, a hydrogen halide and an oxygen-containing gas is contacted at appropriate reaction conditions with a catalyst of copper aluminum borate to form halogenated hydrocarbons.

Hydrocarbon halogenation

A hydrocarbon conversion process using a catalytic composition effective in the catalytic conversion of a feedstock alkane, such as methane, to a higher molecular weight hydrocarbon is disclosed. The composition includes a first component comprising a Group IA metal, a second component comprising Group IIA metal, a third component, the precursor of which comprises a sol (an aqueous suspension of aluminum, silicon, titanium, zinc, zirconium, cadmium or tin) and a fourth component including a Group VIII metal, silver or a combination thereof, present in an amount effective to substantially increase the catalytic activity of the composition. In addition, methods of preparing such catalytic compositions and catalytic compositions prepared by such methods are disclosed.
