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, Hand CO, 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 COare present in a molar ratio of less than 5: 1; b) passing the first product stream comprising CO, Hand COto 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, Hand CO, the fermentation step being operated to provide a conversion of CO of at least 60%, wherein CO, Hand COare recycled from the gaseous third product stream to the reforming process of step (a). |
