Abstract:
1. A method of producing at least one C 1 -C 4 alcohol from syngas, the method comprising: (a) providing a reactor including a catalyst composition comprising cobalt, molybdenum, and sulfur, wherein at least some of said cobalt and some of said sulfur are present as a cobalt-sulfur association having a molar ratio of sulfur to cobalt (S:Co), calculated by assuming all molybdenum is present as MoS (b) flowing syngas into said reactor at conditions effective to produce at least one C (c) injecting additional sulfur, or a compound containing sulfur, into said reactor, in an amount that is sufficient to maintain at least some of said cobalt in a sulfided state, and is further sufficient to maintain said molybdenum in a completely sulfided state wherein said additional sulfur injected in step (c) is contained in one or more compounds selected from the group consisting of elemental sulfur, hydrogen sulfide, dimethyl sulfide, diethyl sulfide, dimethyl disulfide, dibutyl polysulfide, dioctyl polysulfide, diphenyl polysulfide, dicyclohexyl polysulfide, methylthiol, ethylthiol, cysteine, cystine, methionine, potassium disulfide, cesium disulfide, sodium disulfide, and any isomers thereof.
