标题 :Production of mixed alcohols from synthesis gas
发明人：TIJM PETER J; STEVENS REX R
权利人:TIJM PETER J; STEVENS REX R; STANDARD ALCOHOL COMPANY OF AMERICA INC
摘要:Higher mixed alcohols are produced from syngas contacting a catalyst in a reactor. The catalyst has a first component of molybdenum or tungsten, a second component of vanadium, a third component of iron, cobalt, nickel or palladium and optionally a fourth component of a promoter. The first component forms alcohols, while the vanadium and the third component stimulates carbon chain growth to produce higher alcohols.

摘要:A gas rich in methane is prepared by the methanantion of a synthesis gas containing carbon oxides, hydrogen and optionally other gases in the presence of one or more gaseous sulphur compounds, normally in an amount of at least 10 ppm preferably at least 200 ppm by volume, calculated as H2S, with the aid of a catalyst comprising vanadium and/or molybdenum, which during the process is present as one or more sulphides, on a support comprising titanium dioxide. A high activity and a high selectivity for methane are obtained. A further advantage is that, by far, the main constituent of the higher hydrocarbons formed is ethane, which, by conversion into ethylene, is an important raw material in petrochemical synthesis. The selectivity for methane formation may be further improved by promoting the catalyst with compounds, especially sulphides of metals of groups IA, IIA and/or IIIB, particularly cerium. The invention also relates to the catalyst itself which may be prepared by impregnation or coprecipitation techniques.

标题:Tail gas utilization for mixed alcohols production
发明人：RIDLEY JR RICHARD DENHAM; PARDUN MICHAEL EMORY
权利人:STANDARD ALCOHOL COMPANY OF AMERICA INC
摘要:It has been discovered that mixed-alcohol production can utilize the waste tail gas stream from the pressure-swing adsorption section of an industrial hydrogen plant. Some variations provide a process for producing mixed alcohols, comprising: obtaining a tail-gas stream from a methane-to-syngas unit (e.g., a steam methane reforming reactor); compressing the tail-gas stream; separating the tail-gas stream into at least a syngas stream, a CO2-rich stream, and a CH4-rich stream; introducing the syngas stream into a mixed-alcohol reactor operated at effective alcohol synthesis conditions in the presence of an alcohol-synthesis catalyst, thereby generating mixed alcohols; and purifying the mixed alcohols to generate a mixed-alcohol product. Other variations provide a process for producing clean syngas, comprising: obtaining a tail-gas stream from a methane-to-syngas unit; compressing the tail-gas stream; separating the tail-gas stream into at least a syngas stream, a CO2-rich stream, and a CH4-rich stream; and recovering a clean syngas product.

标题:Biogas conversion to mixed alcohols
发明人：RIDLEY JR RICHARD DENHAM; PARDUN MICHAEL EMORY
权利人:STANDARD ALCOHOL COMPANY OF AMERICA INC
摘要:Some variations provide a process for producing mixed alcohols, comprising: purifying a biogas feedstock to generate a renewable natural gas stream comprising methane; introducing the renewable natural gas stream into a methane-to-syngas unit operated at effective conditions to convert the methane to a first syngas stream containing at least H2, CO, and CO2; purifying the first syngas stream, including separating the CO2 from the first syngas stream, and optionally separating some of the H2 from the first syngas stream, thereby generating a clean syngas stream; introducing the clean syngas stream into a mixed-alcohol reactor operated at effective alcohol synthesis conditions with an alcohol-synthesis catalyst, thereby generating mixed alcohols; and purifying the mixed alcohols to generate a mixed-alcohol product. The mixed-alcohol product may be blended with a hydrocarbon fuel, such as gasoline, to produce a blended fuel. The blended fuel has significantly lower carbon intensity than the base hydrocarbon fuel.
