Process for producing alcohols with CH4 to C2 + material comprises Pass food with CH4 and CO2 Reforming non oxidative, produce 1a current with co, H2 and CO2,Through bacterial fermentation, producing 2a current with C2 + alcohols

摘要

The present invention relates to a process for the production of one or more C2+ alcohols. In particular, the present invention relates to a process for the production of C2+ alcohols from a methane-containing feedstock, which process comprises: a. passing said methane-containing feedstock and carbon dioxide to a non-oxidative reforming process to produce a first product stream comprising CO, H 2 and CO 2 , optionally in the presence of steam, but with the proviso that where steam is present in the feed to the reforming process the steam and CO 2 are present in a molar ratio of less than 5:1, b. passing the first product stream comprising CO, H 2 and CO 2 to a bacterial fermentation step wherein it is converted to produce a second product stream comprising one or more C2+ alcohols in the liquid phase and a gaseous third product stream comprising CO, H 2 and CO 2 , the fermentation step being operated to provide a conversion of CO of at least 60%, wherein CO, H 2 and CO 2 are recycled from the gaseous third product stream to the reforming process of step (a).
