ABSTRACT:
Methane-containing gases are produced by passing a hydrocarbon feedstock having a boiling point of not greater than 350.degree. C. and steam over a catalyst at an elevated pressure and at a temperature of from 350.degree. C. to 550.degree. C. at the inlet of the catalyst and an exit of temperature of at least 450.degree. C., the catalyst comprising a reduced catalyst precursor which is resistant to deactivation by polymer formation or by sintering, the catalyst precursor containing (1) from 0 to not more than 0.43% K and from 0 to not more than 0.1% Na, (2) the combined weights of Na+ K does not exceed 0.011 gm atoms/100 gm of catalyst precursor, (3) the ratio of Na:K falls within the area defined by ABCDEO in FIG. 1 of the drawings, and (3) at combined Na+ K weights of from 0 to 0.05% the water loss is not more than 11.2%.
