Singh, D.Pfromm, Peter H.Rezac, Mary E.2010-09-222010-09-222010-10-07http://hdl.handle.net/2097/6238The conventional soybean oil hydrogenation process (metal catalyst on solid support particles slurried in oil, H2 bubbled through the oil) is compared to metal-decorated integral-asymmetric polyetherimide (PEI) membranes, as far as changes in temperature and pressure are concerned. Using metal decorated-polymeric membranes, H2 is supplied to the catalytic sites by permeation from the membrane substructure. As opposed to the slurry process, metal-decorated membranes show only slightly increased trans fatty acid (TFA) formation when the temperature is raised (50-90°C) to accelerate the process. This is likely due to the efficient and to some extent self-regulating H2 supply directly to the catalytic sites on the membrane skin. The hydrogenation rate and TFA formation of the metal decorated membrane process show a minor dependence on pressure.This Item is protected by copyright and/or related rights.
