One-step Synthesis of Dimethyl Ether from CO_2+H_2 in a Three-phase Reactor

One step synthesis of dimethyl ether from carbon dioxide and hydrogen over hybrid catalyst composed of C302 catalyst for methanol synthesis and CM 3 1 catalyst for methanol dehydration in a mechanical agitated autoclave has been studied. Effect of reaction conditions including temperature and pressure on the conversion rate and product selectivity was observed. Because of the presence of the inert liquid phase in this process, syngas conversion can be significantly improved by co product of DME along with methanol. The coproduct strategy improves the thermodynamics and kinetic environment of the reaction system.
