Abstract: Systems and methods are provided for adding a heated stream of light hydrocarbons to a fluidized coking environment to improve liquid product yield and/or reduce coke production. The light hydrocarbons can correspond to C1-C10 hydrocarbons and/or hydrogen. The light hydrocarbons can be heated so that the light hydrocarbons are exposed to an activation temperature of 535° C. to 950° C. and/or an activation temperature higher than the temperature in the coking zone by 50° C. or more for an activation time prior to entering the fluidized coking reactor and/or the coking zone in the fluidized coking environment.

Abstract: The present invention relates to a system and a process for converting heavy oils into light hydrocarbon products and electric power. The system comprises a CFB reactor for thermal cracking of heavy oils to generate light hydrocarbon products, coupled with a CFB boiler power plant for converting coke particles produced in the CFB reactor into flue gas and then producing steam for generation of electric power. The system and process of the present invention efficiently produces valuable products from heavy oils (electric power and a full range of hydrocarbon products ranging from Heavy Coker Gas Oil to refinery fuel gas) with negligible coke production and minimal or no generation of low heating value gas.
