  • Patent number: 7943038
    Abstract: Processes for producing one or more olefins are provided. In one or more embodiments, a doped catalyst can be prepared by fluidizing one or more coked-catalyst particles in the presence of one or more oxidants to provide a fluidized mixture. At least a portion of the coke can be removed from the coked-catalyst particles to provide regenerated catalyst particles. One or more doping agents can be distributed throughout the fluidized mixture, depositing on the surface of the regenerated catalyst particles to provide doped catalyst particles. One or more hydrocarbon feeds can be fluidized with the doped catalyst particles to provide a reaction mixture which can be cracked to provide a first product containing propylene, ethylene, and butane.

  • Patent number: 7867378
    Abstract: A method is described for co-processing of ethanol and hydrocarbons from petroleum refining, which are introduced separately in two reaction zones of a reactor of a fluidized catalytic cracking unit. The process combines conversion of ethanol into ethene and conversion of hydrocarbons into other lighter hydrocarbon fractions, to produce ethene in quantities of 15 to 90 wt % in the fuel gas fraction obtained during the process.
