Patent

CA 2626365

A fluid cracked naphtha stream is subjected to hydrodesulfurization and fractionation, preferably simultaneously in catalytic distillation reactors. The overheads and a portion of the bottoms from the fractionation are recombined to produce a naphtha blend having an ASTM D-8695% point greater than the end point of the overheads and less than the ASTM D-86 95% point of the bottoms.

Selon l'invention, un flux de pétrole de craquage catalytique en lit fluidisé est soumis à une hydrodésulfuration et à un fractionnement, de préférence de façon simultanée, dans des réacteurs de distillation catalytique. Les distillats de tête et une partie des résidus du fractionnement sont recombinés pour produire un mélange de pétrole ayant un point 95 % ASTM D-86 supérieur au point final des distillats de tête et inférieur au point 95 % ASTM D-86 des résidus.
