Abstract
Compositions comprising boron-promoted reducible metal oxides (especially reducible oxides of Mn) and optionally containing alkali and alkaline earth metal components are disclosed, as well as use thereof for hydrocarbon conversions characterized by formation of byproduct water. Particular processes comprise the conversion of methane to higher hydrocarbons and the dehydrogenation of dehydrogenatable hydrocarbons, e.g., dehydrogenation of C.sub.2 -C.sub.5 alkanes to form the corresponding olefins.
Claims41
In an improved method for converting methane to higher hydrocarbon products which comprises contacting a gas comprising methane at synthesizing conditions with a solid comprising at least one reducible oxide of at least one metal which oxides when contacted with methane at synthesizing conditions are, reduced and produce higher hydrocarbon products and water, the improvement which comprises conducting the contacting in the presence of a promoting amount of at least one member of the group consisting of boron and compounds thereof.
In an improved method for converting methane to higher hydrocarbon products which comprises contacting a gas comprising methane at synthesizing conditions with a solid comprising:
- (a) at least one reducible oxide of at least one metal which oxides when contacted with methane at synthesizing conditions are reduced and produce higher hydrocarbon products and water and (b) at least one member of the group consisting of alkaline earth metals and compounds thereof;
- the improvement which comprises conducting the contacting in the presence of a promoting amount of at least one member of the group consisting of boron and compounds thereof.
