Abstract:
1. A method of fluid catalytic cracking for production of middle distillates of low aromaticity, characterized in that it comprises the following steps: a) submitting a feed A, consisting of heavy fractions of hydrocarbons, such as a heavy vacuum gas oil, or an atmospheric residue, or a mixture thereof in any proportions, to a reaction of fluid catalytic cracking, in the absence of added hydrogen, in the riser of a dense-bed FCC reactor, operated: b) withdrawing an effluent B obtained in the above reaction at the top of the dense-bed catalytic cracking reactor, submitting it to fractionation in a fractionating tower that produces a gas fraction C, which is sent to a gas recuperation section, plus a light naphtha fraction D, and a middle distillate E, both of low aromaticity, and sending these for subsequent treatment and sale.
