Abstract: The present invention relates to a gas-solid separation device specially adapted to the external risers of catalytic cracking units. The device comprises a pipe (19) forming substantially an angle of 90° with respect to a riser (2), said pipe (19) dividing into two tubular sections (4) forming between them an angle 2*γ, γ being between 5° and 85°. This device simultaneously makes it possible to channel the stripping gases and improves the overall efficiency of the separation by virtue of better control of the contact time. The present invention also relates to a catalytic cracking process using said gas-solid separation device.

Abstract: The present invention relates to a process for desulfurizing a cracked naphtha containing organic sulfur compounds comprising the following steps: a) feeding the cracked naphtha to a distillation column comprising a bottom reboiler; b) fractionating said cracked naphtha into a light naphtha fraction and a heavy naphtha fraction which is removed as bottoms from the distillation column; c) feeding the heavy naphtha fraction and hydrogen to a hydrodesulfurization unit containing a hydrodesulfurization catalyst to produce a desulfurized heavy naphtha effluent. The process further comprises a step of providing heat to the distillation column by an intermediate reboiler powered with a heat source having a temperature lower than that one of the bottom reboiler.
