Abstract
Methods and systems or devices for synthesis of dimethyl ether (DME) from carbon dioxide and hydrogen are provided. A high surface area hollow fiber catalytic membrane reactor such as with hollow fibers coated with a water permeable membrane material is used. The reactor also contains a bi-functional methanol synthesis component and dehydration catalyst component such that the two-step reaction takes place on the catalyst surface. Produced water permeates through the membrane, exiting the reactor immediately after it is formed. Unreacted reactants and products flow to the reactor exit.
