PREPARING PROCESS OF METHANOL, DIMETHYL ETHER AND LOWER OLEFIN FROM SYNTHESIS GAS

摘要

Disclosed is a preparing process of methanol, dimethyl ether and lower olefin from synthesis gas, which comprises contacting synthesis gas with catalyst under the conditions of the conversion of synthesis gas to methanol, dimethyl ether and lower olefin. The catalyst contains amorphous alloys consisting of M component and X component, wherein the X component is B and/ or P, and the M component is two or more selected from subgroups of IIIA, IVA, VA, IB, IIB, IVB, VB, VIB, VIIB, VIII and lanthanum-series metal element of periodic table of chemical elements. The present method has very high conversion of carbon monoxide, high selectivity of objective product and high utilization ratio of carbon.
