Abstract
The invention relates to a method for processing coke oven gas, said coke oven gas containing hydrogen, wherein the coke oven gas is at least partially integrated into a method for producing dimethyl ether in conjunction with a gas containing carbon monoxide and/or carbon dioxide, whereby a DME-containing product gas is formed. At the outset of the method for the formation of dimethyl ether, a ratio of hydrogen to carbon monoxide, weighted with the carbon dioxide concentration (formula (I)), of 0.9 to 1.1 is set, wherein the DME-containing product gas is integrated into a method for converting dimethyl ether to olefins, whereby an olefin-containing product gas is formed, and wherein olefins, in particular ethylene and/or propylene, is/are separated from the olefin-containing product gas by means of separating methods.
