Abstract
A stable system for producing liquid products such as ethanol, butanol and other chemicals from syngas components contacts CO or a mixture of COand Hwith a hydrophilic membrane under anaerobic conditions and transfers these components into contact with microorganisms contained as a biofilm on the membrane. Maintaining the microorganisms as a biolayer on the surface of the membrane facilitates cleaning of the membrane surface that retains the biofilm. In addition the shell gas space that surrounds the membranes may be flooded to reduce or remove the biofilm. Agitation of the liquid, by for example the bubbling of gas in the surrounding shell space, can fully or partially remove the biofilm from the membrane.
