  • Publication number: 20110282124
    Abstract: An embodiment can be a process for catalytically cracking a hydrocarbon feed. The process can include providing the hydrocarbon feed including an effective amount of one or more C4-C6 olefins for producing at least one light olefin to a riser. Typically, at least about 99%, by mole, of the hydrocarbon feed is a gas.

  • Patent number: 8007728
    Abstract: One exemplary embodiment can be a fluid catalytic cracking system. The fluid catalytic cracking system can include a reaction zone including a riser having a top and a bottom adapted to receive spent catalyst at a first elevation and regenerated catalyst at a second elevation. Typically, the first elevation is lower than the second elevation. Additionally, the fluid catalytic cracking system can include a gas distributor contained near the bottom of the riser in communication with a hydrocarbon feed.
