Abstract
Disclosed is a catalytic cracking process for the production of light olefins from a hydrocarbon feedstock using fast fluidization, which is a preferred process for more efficiently increasing the production of light olefin hydrocarbons. According to this invention, a fast fluidization regime is applied to a fluidized bed catalytic cracking process of producing light olefins using zeolite, such that a volume fraction and distribution of the catalyst sufficient to induce the catalytic cracking reaction can be provided, thus effectively enhancing the production of light olefin hydrocarbons, in particular, ethylene and propylene, at high selectivity.
