    摘要: A method wherein a gas stream containing hydrogen, a carbon oxide and hydrogen sulfide is first passed in contact with a catalyst comprising a porous alumina supported sulfided metal selected from the group consisting of molybdenum (Mo), chromium (Cr), tungsten (W), manganese (Mn), nickel (Ni), iron (Fe), zinc (Zn), cobalt (Co), copper (Cu), tin (Sn), vanadium (Va) and mixtures thereof, optionally promoted by an alkali metal sulfide, to convert said hydrogen, carbon oxide and hydrogen sulfide to methyl mercaptans, (primarily methanethiol (CH.sub.3 SH)), and the gas stream containing the methyl mercaptans are passed in contact with a catalyst comprising a supported metal oxide or a bulk metal oxide in the presence of an oxidizing agent and for a time sufficient to convert at least a portion of the methyl mercaptan to formaldehyde (CH.sub.2 O), and sulfur dioxide (SO.sub.2).

    摘要: An improved process for continuously producing oxygen-containing compounds by the oxo process from olefins, carbon monoxide and hydrogen at a pressure of 5 to 1000 bar and at a temperature of 50.degree. to 200.degree. C. in the presence of a metal of Group VIII and/or a compound thereof as catalyst is disclosed. According to the invention, the unreacted olefin carbon monoxide and hydrogen is passed to a high pressure reactor wherein unreacted olefin is reacted under oxo process conditions to form oxygen-containing compounds.
