Abstract:
According to the 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.
