ABSTRACT:
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.degree.-400.degree. C., a space velocity of 2000-8000 hr.sup.-1 and a pressure of atmospheric pressure -50 kg/cm.sup.2.
