Abstract

PURPOSE: To obtain a liquefied having high octane value, by bringing a synthesis gas consisting of CO and H₂ into contact with a methanol synthesizing catalyst and an acid type dehydrating derivative to form dimethyl ether, CO₂ and H₂, separating CO₂ from noncondensible gas by a membrane and bringing the purified gas into contact with a zeolite catalyst.

CONSTITUTION: A synthesis gas 101 consisting of a mixture of CO and H₂ pre pared from natural gas is fed to a dimethyl ether synthesis reactor 1, brought into contact with a mixture of a methanol synthesis catalyst and an acid type dehydrating catalyst to give a reaction product 103 consisting of dimethyl ether and carbon dioxide. Then the reaction product is sent a hydrogen separator 3 to separate hydrogen, which is circulated to the dimethyl ether synthesis reactor 1. The first-stage reaction product from which hydrogen is separated is separated into carbon dioxide and other noncondensible gases by a separating membrane 4, the purified gas is fed to a gasoline synthesis reactor 2 and brought into contact with a crystalline silicate zeolite catalyst of transition metal to give a liquefied hydrocarbon 116.
