Integrated process for refining whole crude oil

Claim 1

An integrated process for producing light naphtha, heavy naphtha and a fuel oil fraction from whole petroleum crude oil comprising the steps of: a. passing said whole petroleum crude oil containing sulfur, nitrogen and metal impurities directly to a hydrofining zone; b. hydrofining said crude oil in the presence of a hydrofining catalyst and hydrogen; c. passing hydrofined crude oil to an atmospheric distillation zone; d. distilling an admixture of said hydrofined crude oil with hydrocracked products as hereinafter identified; e. recovering a light naphtha fraction from said distillation zone, said fraction being essentially free of mercaptans; f. recovering a low sulfur, heavy naphtha reformer feed stock fraction from said distillation zone; g. passing a low sulfur, low nitrogen atmospheric distillation bottoms from said distillation zone to a vacuum distillation zone; h. recovering a low sulfur fuel oil and cracking feed fraction from said vacuum distillation zone; i. passing said cracking feed fraction to a hydrocracking zone; j. hydrocracking said fraction at a temperature in the range of 650* to 750* F. and a pressure in the range of 1,000 to 3,000 p.s.i.g. in the presence of 5,000 to 10,000 s.c.f./B of hydrogen and a catalyst comprising a metal hydrogenation component and a crystalline aluminosilicate zeolite; k. recovering hydrocracked products comprising a major amount of naphtha, and l. passing said hydrocracked products to the atmospheric distillation zone of step (c) to provide said admixture of step (d).
