Dimethyl ether synthesis from CO_2-rich syngas in the lpdme process

摘要

The liquid phase dimethyl ether, LPDME, synthesis process was developed by the University of Akron and EPRI team as a means to overcome the chemical equilibrium involved in the synthesis of methanol from a syngas feed. This process alleviates the methanol synthesis equilibrium limitation by converting the product into dimethyl ether. The conversion is performed in a slurry reactor and involves the use of a dual catalyst mixture for the single-stage conversion of syngas to DME.
