Zusammenfassung:Herein disclosed is a method of producing dimethyl ether (DME) comprising introducing one or more feed streams comprising methane and carbon dioxide into a reformer to generate synthesis gas; and converting synthesis gas to DME in one step. In some cases, the reformer comprises a Ni catalyst. In some cases, the reformer is a pressurized fluidized bed dry reforming reactor. In some cases, the reformer comprises a hydrogen membrane. The hydrogen membrane removes hydrogen contained in the synthesis gas and shifts reforming reactions toward completion.
