Abstract

A system and method for converting natural gas to dimethyl ether (DME) are provided. An exemplary system includes a purified natural gas feed, a combustion chamber to combust a first portion of the natural gas to provide heat and an exhaust gas, and a separator to separate water and COfrom the exhaust gas to form a first feed, a second portion of the natural gas forms a second feed. The system also includes a bi-reforming reactor comprising a bi-reforming catalyst to react the first feed and the second feed to form hydrogen and carbon monoxide, and a dimethyl ether (DME) reactor comprising a DME catalyst to form DME from the hydrogen and carbon monoxide.
