    摘要: An improved apparatus and method for the fluidized catalytic cracking (FCC) of hydrocarbons. Turbulence generation means disposed on the internal surface of an FCC riser-reactor are utilized to provide for a more uniform catalyst flow pattern within the riser-reactor and to thereby provide for a better conversion and product slate.

    摘要: A novel apparatus and process, including a perforated-pipe sparger, for atomizing a liquid stream is disclosed. This novel apparatus and process can be utilized in a fluidized catalytic cracking process or in a coking process for atomizing an oil stream prior to contact with a fluidized catalyst.
