<p>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).</p> |
