Abstract
A process is provided for the manufacture of methyl mercaptan with substantial reduction of by-product methane by intimate mixture of carbon oxide, sulfur or hydrogen sulfide and hydrogen at elevated temperature and pressure with a single-phase, solid catalyst system comprising a porous alumina-containing support upon which is deposited a mixture of manganese sulfide and alkali metal sulfide.
Claims4
A composition of matter comprising a solid catalyst system of from 10 to about 90%, based on the weight of said system, of a support comprising alumina upon which is deposited from about 90 to about 10%, based on the weight of said system, of a mixture of:
- (a) from 2 to 95%, based on the weight of said mixture, of the sulfide of manganese,
- (b) from 0 to 90% of at least one sulfide selected from the group consisting of sulfides of iron, nickel, zinc and chromium, and
- (c) from 5 to 80%, based on the weight of said mixture, of an alkali metal sulfide, the total of (a), (b) and (c) equaling 100%.
