Abstract
Numerical analysis of a porous type membrane reactor system for gasoline steam reforming has been done. It was clarified that restraint of steam permeation was important for high reformer efficiency in addition to promoting permeation of product gases. For more improvement of the reformer efficiency, two effective controls were proposed. First one was the pressure control in the purge lines to control the permeation rates at each load. Second one was the recirculation control of non permeated gases in the feed lines to enhance the reaction rate. Using these controls, the reformer efficiency was estimated at 75%. Moreover both performance of catalyst and membrane should be improved for 80% reformer efficiency.
