Ethanol and other liquid products are produced by contacting syngas components such as CO or a mixture of CO2 and H2 with a surface of a membrane under anaerobic conditions and transferring these components into contact with a biofilm on the opposite side of the membrane. These steps provide a stable system for producing liquid products such as ethanol, butanol and other chemicals. The gas fed on the membrane's gas contact side transports through the membrane to form a biofilm of anaerobic microorganisms that converted the syngas to desired liquid products. The system can sustain production with a variety of microorganisms and membrane configurations.
A process for converting a feed gas containing at least one of CO or a mixture of CO2 and H2 under anaerobic conditions to a liquid product comprising at least one of ethanol, propanol, n-butanol, acetic acid, propionic acid and butyric acid:
