Abstract
A method for synthesizing hydrocarbons from a methane source which comprises contacting methane with an oxide of Pr. The oxide is reduced by the contact which is carried at about 500.degree. to 1000.degree. C. Reducible oxides of Pr are regenerated by oxidizing the reduced composition with oxygen. The oxide Pr.sub.6 O.sub.11 is particularly effective in the process.
Claims3
A method for synthesizing hydrocarbons from a methane source which comprises:
- (a) contacting at a temperature within the range of about 500.degree.-1000.degree. C., a gas comprising methane and a solid comprising a reducible oxide of Pr, said contacting producing C.sub.2 +hydrocarbons, coproduct water and solids comprising a reduced Pr oxide, and said contacting being carried out in the substantial absence of catalytically effective Ni, Rh, Pd, Ag, Os, Ir, Pt, Au and compounds thereof;
- (b) recovering C.sub.2 +hydrocarbons;
- (c) at least periodically contacting the solids comprising reduced Pr oxide with an oxygen-containing gas to produce a solid comprising a reducible Pr oxide;
- and
- (d) contacting a gas comprising methane with the solids produced in step (c) as recited in step (a).
