Zusammenfassung:Integrated methods and systems are disclosed for the production of dimethyl ether. The method may include reforming natural gas to syngas in a first reactor; contacting the syngas produced in the first reactor with a catalyst system in a second reactor to produce dimethyl ether and carbon dioxide; and supplying steam as a cofeed to at least one of the first reactor and the second reactor in an amount sufficient to achieve a Mm value of 1.4 to 1.8 or to improve the hydrocarbon or oxygenate selectivity.
