The invention relates to processes for production of 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 formed in the dry-reforming step are converted into dimethyl ether, wherein the dry-reforming step and the synthesis step are carried out at identical pressures or at pressures, which do not differ more than 3 bar, preferably not more than 1 bar.

Method for producing dimethyl ether from methane

The invention relates to a method and a device for generating hydrogen (), wherein an input () comprising carbon is fed longitudinally through a tube-shaped reaction chamber (Z), together with water steam (), and is thereby converted by steam reforming, and hydrogen () formed during steam reforming is continuously drawn off out of the reaction chamber (Z) through a separating wall (T), said wall being selectively hydrogen-permeable at least in segments, and at a pressure less than the pressure in the reaction chamber (Z) and greater than the ambient pressure, having greater purity than product (), characterized in that a separating wall (T) is used, the selectively hydrogen-permeability segments thereof being disposed such that a hydrogen partial pressure drop exists over the entire surface of each of such segments between the reaction chamber side and the hydrogen extraction side (W).
