50097-98-I Mixed-Conducting Membranes for the Spontaneous Oxidative Dehydrogenation of Alkanes to Olefins--Eltron Research, Inc., 5660 Airport Boulevard, Boulder, CO 80301-2340; (303) 440-8008 Dr. Shane E. Roark, Principal Investigator Ms. Eileen E. Sammells, Business Official DOE Grant No. DE-FG03-98ER82571 Amount: $75,000 Current methodologies for the production of low molecular weight olefins utilize highly endothermic processes, which require a large input of energy to maintain. This project addresses the development of an approach for synthesizing olefins from alkanes with much greater energy efficiency than existing technologies. The goals of this project will be accomplished by combining active oxidative dehydrogenation catalysts with advanced proton/electron-conducting membranes for spontaneous conversion of alkanes to olefins. Protons formed from the dehydrogenation will be removed from the reaction sites through the membrane, allowing product yields to exceed the levels imposed by thermodynamic equilibrium. Phase I will involve optimization of the catalyst and membrane materials and the reaction conditions for the proposed olefin synthesis technique. The optimum parameters will be incorporated into a prototype tube reactor, which will be tested for performance. Commercial Applications and Other Benefits as described by the awardee: This technology will lead to the development and commercialization of a low-cost alternative for olefin production. Conversion of ethane, propane and butane to the corresponding olefins is projected to add an additional material value of several billion dollars per year. Refinement of this technology will lead to the development of energy-efficient reactors for a variety of industrial synthesis applications. _
