An integrated process and system for employing low conversion rWGS to prepare a gas fermentation feed stream from a CO.sub.2 source and a hydrogen source in order to produce at least one gas fermentation product. Low conversion rWGS reactors may (1) employ a wider selection of inorganic catalysts then rWGS reactors requiring high temperature operation, (2) allow for use of an electric heater instead of a fired heater to preheat feed stream to the low conversion rWGS reactor, and (3) extend rWGS catalyst life by reducing the amount of water produced in the rWGS reaction.

Methods and systems for the production of one or more products from a gas stream produced in a methanol production process. The method comprises converting at least a portion of a methane feedstock to a substrate comprising CO and H2. The substrate comprising CO and H2 is anaerobically fermented in a bioreactor to produce one or more alcohols. The method and system may further include process for the production of methanol processes for the production of acetic acid.
