Abstract
A stable method for producing liquid products such as ethanol, propanol, butanol and other chemicals from syngas components that contacts CO or a mixture of COand Hwith a highly porous side of an asymmetric membrane under anaerobic conditions and transfers these components into contact with microorganisms contained within bio-pores of the membrane. A liquid contacting side of the membrane utilizes a dense layer to control hydration of the bio-pores with a liquid phase. The gas feed directly contacts the microorganisms in the bio-pores and maximizes their utilization of the syngas. Metabolic products produced by the microorganisms leave the membrane through the side opposite the entering syngas. This method establishes a unitary direction across the membrane for the supply of the primary feed source to the microorganisms and the withdrawal of metabolically produced products. The feed and product flow improves productivity and performance of the microorganism and the membrane.
