Process for producing lower olefinic hydrocarbons from methanol

摘要

Lower olefinic hydrocarbons are produced from methanol in a high yield and with a high selectivity by bringing methanol into contact with a metallosilicate catalyst of the formula Si/Me wherein atomic ratio of Si/Me is 25-3200 and Me is Fe, Ni or Co at a temperature of 250 DEG -400 DEG C., a space velocity of 2000-8000 hr-1 and a pressure of atmospheric pressure -50 kg/cm2.
