| 摘要 |
Hydrocarbons containing 6 or fewer carbon atoms in the molecule are produced by reacting a feedstock comprising a hydrocarbon different from the intended product and containing 2 or more carbon atoms in the molecule and/or a hydrocarbon derivative, for example an oxygenated derivative such as methanol or dimethyl ether, over a catalyst comprising zeolite MCH. Zeolite MCH is described and claimed in U.K. patent application 80/32463. Preferred reactions include cracking of higher hydrocarbons to produce olefins and the conversion of methanol and/or dimethylether to olefins, especially ethylene and propylene. |
