NOVELTY - Producing (M1) at least two carbon containing alcohol from a methane-containing feedstock involves: passing the methane-containing feedstock and carbon dioxide to a non-oxidative reforming process, optionally in presence of steam, but with the proviso that where steam is present in the feed to the reforming process, the steam and carbon dioxide are present in a molar ratio of less than 5:1; passing first product stream of carbon monooxide, hydrogen and carbon dioxide to bacterial fermentation step.    USE - For production of at least two carbon containing alcohol from a methane-containing feedstock (claimed) e.g. ethanol and heavier alcohol, 2-6C alcohol or 2-4C alcohol i.e. ethanol, propanol and butanol (iso-butanol and n-butanol).    ADVANTAGE - The method produces at least two carbon containing alcohol from a methane-containing feedstock; uses bacterial fermentation and synthesis of gas to alcohols can be operated with relatively high carbon monoxide conversion, such that the product stream has a relatively low amount of carbon monoxide in it. Thus the carbon monoxide can be economically recycled to the earlier reforming process; avoids the need for any specific separation of carbon monoxide from carbon dioxide in the product stream prior to recycle. The fermentation step is operated to provide a conversion of CO of at least 70 (preferably at least 80)%. The carbon monoxide conversion in a bacterial fermentation process is the result of a combination of a number of factors that can be controlled by the operator of the process.    DETAILED DESCRIPTION - Production (M1) of at least two carbon containing alcohol from a methane-containing feedstock involves: passing the methane-containing feedstock and carbon dioxide to a non-oxidative reforming process to produce a first product stream comprising carbon monooxide (CO), hydrogen (H2) and carbon dioxide (CO2), 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 CO2 are present in a molar ratio of less than 5:1; passing the first product stream to a bacterial fermentation step, where it is converted to produce a second product stream comprising at least two carbon containing alcohol in the liquid phase and a gaseous third product stream comprising CO, H2 and CO2, the fermentation step is operated to provide a conversion of CO of at least 60%, where CO, H2 and CO2 are recycled from the gaseous third product stream to the reforming process of first step.
