  • PROCESS FOR THE MANUFACTURE OF METHYMERCAPTAN
    Publication number: 20070213564
    Abstract: The present invention refers to a continuous process for the manufacture of methyl mercaptan using Mo-O—K-based catalysts. It is further described that the total selectivity of methylmercaptan can be increased by at least 1% by lowering the total gas hourly space velocity. The invention further refers to a process for the preparation of a solid, preformed catalyst system.

  • PROCESS FOR THE CONTINUOUS PRODUCTION OF METHYLMERCAPTAN
    Publication number: 20060229474
    Abstract: The invention relates to a process for the continuous production of methylmercaptan by reacting a starting gas mixture of methanol and hydrogen sulphide in the gas phase at a reaction temperature between 200 and 600° C. and an operating pressure of 1.5 to 40 bar on a catalyst in a multi-bed reactor.
