PROCESS FOR THE CONVERSION OF SYNTHESIS GAS TO OLEFINS

摘要

The present invention relates to a process for converting a gas mixture comprising CO and H2 to olefins, comprising (1) providing a gas mixture (G0) comprising CO and H2; (2) providing a catalyst (C1) for conversion of CO and H2 to dimethyl ether; (3) contacting the gas mixture (G0) with the catalyst (C1) to obtain a gas mixture (G1) comprising dimethyl ether and CO2; (4) providing a catalyst (C2) for conversion of dimethyl ether to olefins; (5) contacting the gas mixture (G1) comprising dimethyl ether with the catalyst (C2) to obtain an olefin-comprising gas mixture (G2).
