    摘要: The present invention relates to an improved design for use in fluid cracking processes, preferably used in either a fluid catalytic cracking (“FCC”) process or a fluid coking process. In particular, the present invention relates to an apparatus and process for improving the separation and distributing spent catalyst and gases in a spent catalyst riser associated with a fluid cracking process, and most preferably for use in a spent catalyst riser associated with an FCC regenerator vessel. A novel catalyst distributor design and associated processes are presented herein which significantly improve combustion in the dense-phase fluidized catalyst bed of a regenerator and results in improved regenerator dense bed combustion and lower migration of oxygen into the regenerator overhead region. As a result, afterburn is significantly reduced in the regenerator and higher catalyst bed temperatures are achieved with significantly more uniform bed temperatures due to the improved combustion characteristics in the dense-phase fluidized catalyst bed.

    摘要: A method which controls sedimentation occurring at a heat exchanger for cooling hydrodesulfurization/hydrocracking residue containing asphaltenes at a high content and thereby prevents fouling of the heat exchanger is disclosed. A method for preventing fouling of a heat exchanger for cooling hydrodesulfurization/hydrocracking residue, which injects flux oil into hydrodesulfurization/hydrocracking residue containing asphaltenes at 1% by mass or more, wherein the flux oil is at least one species of residue selected from the group consisting of crude vacuum distillation residue and fluidized catalytic cracking residue, and injected into the hydrodesulfurization/hydrocracking residue to control its actual sediment content at 0.2% by mass or less, determined in accordance with IP-375 is also disclosed.
