    • Disclosed is a novel process for producing propylene by using ethylene and at least one member selected from methanol and dimethyl ether as starting materials, which can reduce the amount of unreacted ethylene to be recycled and has low equipment cost and running cost. Specifically disclosed is a process for producing propylene by using ethylene and at least one member selected from methanol and dimethyl ether as starting materials, which comprises reacting ethylene and at least one member selected from methanol and dimethyl ether under specific conditions to produce a fluid containing an olefin having 4 or more carbon atoms, and then reacting at least a part of the olefin having 4 or more carbon atoms contained in the fluid with at least one member selected from methanol and dimethyl ether under specific conditions, thereby producing propylene.

    • A process for producing propylene efficiently from a raw material mixture comprising an olefin having four or more carbon atoms and at least one of methanol and dimethyl ether with high selectivity and in a high yield by inhibiting the production of by-products such as aromatic compounds or paraffins while keeping the reaction rate at a high level. The process comprises diluting a raw material mixture comprising an olefin having four or more carbon atoms and at least one of methanol and dimethyl ether with a diluent (C) (which consists of one or more members selected from among paraffins, aromatic compounds, steam, carbon dioxide, carbon monoxide, nitrogen, argon, and helium)in such a way as to satisfy the requirement (A) that the ratio of the amount by mole of the olefin fed into the reactor to the sum of the amount by mole of methanol fed into the reactor and twice the amount by mole of dimethyl ether fed thereinto is 0.5 to 10 and the requirement (B) that the total concentration of the olefin, methanol and dimethyl ether in the whole component fed into the reactor is 20 to 80% by volume, and subjecting the obtained dilution to catalytic reaction. ® KIPO & WIPO 2009
    • 从包含具有四个或更多个碳原子的烯烃和至少一种甲醇和二甲醚的原料混合物中有效地生产丙烯的方法,通过抑制芳族化合物或其衍生物等副产物的高选择性和高收率 石蜡,同时保持反应速度在高水平。 该方法包括将包含具有四个或更多个碳原子的烯烃和至少一种甲醇和二甲醚的原料混合物与稀释剂(C)(其由选自石蜡,芳族化合物,蒸汽, 二氧化碳,一氧化碳,氮气,氩气和氦气)以满足(A)的要求,即进料到反应器中的烯烃的摩尔比与甲醇的摩尔数之和 进料到反应器中,加入二甲基醚的摩尔比为两倍,为0.5-10,并且要求(B)在进料到反应器中的全部组分中烯烃,甲醇和二甲醚的总浓度为20-80% 并将所得稀释液进行催化反应。 ®KIPO&WIPO 2009
