Fluid Catalytic Cracking process and apparatus for miximizar Light Olefins or olefin Light and Middle distillates

摘要

Disclosed is an apparatus and Process for Fluid Catalytic Cracking, which provides an efficient conversion of heavy Hydrocarbon feeds to Light Olefins, AROMATICS, and Gasoline. A countercurrent flow reactor that operates in Turbulent Fluidization regimes of Bubbling or is integrated with a Lifting Fluid Catalytic Cracking reactor.A Hydrocarbon feed is heavy catalytic cracked Gasoline and Light Olefins in the Reactor Riser reactor in co current Flow.To improve the production and the selectivity of Light olefin Hydrocarbon products from the Reactor of Elevation, such as in the range of C 4 Hydrocarbon and naphtha, can be recycled and processed in the Reactor in countercurrent Flow.The Integration of flow reactor in countercurrent reactor with a Lifting System of a FCC Catalyst regeneration and conventional Heat balance can address problems commonly associated with Cracking processes in two stages, Can Substantially increase the conversion Global Production of Light Olefins,And / or may increase the ability to process heavier feedstock.
