Catalyst for synthesizing methyl mercaptan from synthesized gas contg. hydrogen sulfide

Catalyst for synthesizing methyl mercaptan from synthesized gas contg. hydrogen sulfide

The catalyst has one carrier selected from SiO2, gamma-Al2O3, TiO2 or RE oxide and its active component Mo-S-K radical is transformed from precursor K2MoS4 or (NH4)MoS4+K2CO3. Under the conditions of295 deg.c temperature, normal pressure, volume proportion of high-sulphur synthesis gas CO-H2-H2S bei...

Zusammenfassung:The catalyst has one carrier selected from SiO2, gamma-Al2O3, TiO2 or RE oxide and its active component Mo-S-K radical is transformed from precursor K2MoS4 or (NH4)MoS4+K2CO3. Under the conditions of295 deg.c temperature, normal pressure, volume proportion of high-sulphur synthesis gas CO-H2-H2S being 1 to 2 to 0.1-1, and 2000-5000/hr space velocity, the catalyst can result in methyl mercaptan space-time yield of 0.15g/hr each gram of catalyst and selectivity of 98.5%.
