ABSTRACT:
Disclosed is a process for increasing production of light olefinic hydrocarbons from hydrocarbon feedstock by catalytic cracking. In the process, an effective separation process structure and recycle method of light olefins are used not only to increase the productivity and efficiency of an overall process, thus effectively increasing the production of light olefins, but also to simplify the overall process.
