Use of a catalyst comprising a bimetallic compound and a promoter for the production of methyl mercaptan
A Mo-W bimetallic catalyst with a promoter on ZrO2 or Al2O3 supports improves methyl mercaptan production by increasing selectivity and productivity while allowing carbon monoxide recycling, addressing the inefficiencies of existing catalysts.

AI Technical Summary
Existing catalysts for producing methyl mercaptan suffer from low selectivity and productivity, with significant by-products such as carbon dioxide being produced, necessitating improved catalysts for enhanced performance.
A catalyst comprising a Mo-W bimetallic compound and a promoter, preferably potassium, supported on a metal oxide like ZrO2 or Al2O3, is used to produce methyl mercaptan from carbon monoxide, hydrogen sulfide, and hydrogen, with a process that includes consecutive reactions without intermediate purification, allowing recycling of hydrogen sulfide.
The catalyst achieves improved methyl mercaptan selectivity and productivity, with carbon monoxide as the main by-product that can be reused, enhancing overall process efficiency.
