There is provided a process for producing a hydrocarbon product from a feed gas by passing at least a portion of a feed gas stream comprising hydrogen and carbon monoxide to a first separation zone and physically separating the feed gas stream, as for example by use of a membrane, into a first hydrogen stream wherein the ratio of hydrogen to carbon monoxide is greater in the feed gas stream and thereafter passing the first hydrogen stream to a product reaction zone to form a mixed product stream, which in turn undergoes physical separation to form a second hydrogen stream for selective recycle to the product reaction zone and a product stream including a hydrocarbon product such as methanol or methane. |
