METHOD FOR PRODUCING DIMETHYL ETHER FROM METHANE

摘要

The invention relates to a method for producing dimethyl ether from methane or natural gas, comprising a dry reforming step, wherein methane and carbon dioxide are converted into carbon monoxide and hydrogen, and a DME synthesis step, wherein the carbon monoxide and hydrogen obtained in the dry reforming step are converted into dimethyl ether. According to the invention, said dry reforming step and the synthesis step are carried out at equal pressures or pressures which do not differ from each other for more than 3.0 bar, preferably not more than 1.0 bar.
