Abstract
A membrane supported bioreactor arrangement and method for anerobic conversion of gas into liquid products including membrane modules having hollow fibers, each of the hollow fibers formed from an asymmetric membrane wall having a porous outer layer defining biopores for retaining a porous biolayer about the outer surface of the membrane wall and a less permeable hydration layer around the hollow fiber lumen; a membrane vessel for retaining the membrane modules in a process gas for formation of the biolayer on the outer surface of the hollow fiber wall by interaction of microorganisms with a process gas and for the production of a liquid product, wherein the membrane vessel retains the membrane modules in a common horizontal plane; provides a seal between contents of the membrane tank and ambient atmosphere; and includes a liquid supply conduit for communicating the process liquid with the hollow fiber lumens of the hollow fibers.
