Abstract
A submerged membrane supported bioreactor for anaerobic conversion of gas into liquid products including a plurality of membrane modules having a plurality of hollow fibers, each of the plurality of hollow fibers having a gas permeable hollow fiber wall defining a hollow fiber lumen and an outer surface; a membrane tank for retaining the membrane modules at least partially submerged in a process liquid for formation of a biofilm 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 that mixes with the process liquid, wherein the membrane tank retains the membrane modules in a common horizontal plane; a seal between contents of the membrane tank and ambient atmosphere; and a gas supply conduit for communicating the process gas with the hollow fiber lumens of the hollow fibers.
