Process for producing ethylene and propylene |
摘要 |
A process for efficiently and stably producing ethylene and propylene which comprises bringing a hydrocarbon feedstock comprising at least one C4-12 olefin into contact with a zeolite-containing catalyst to obtain a reaction mixture containing ethylene and propylene, separating the reaction mixture into a fraction comprising ingredients ranging from hydrogen to C3 hydrocarbons and a fraction comprising C4 and higher hydrocarbons, and recycling the C4 and higher hydrocarbons as they are to a reactor. |
