ABSTRACT:
The present invention relates to a hydrocatalytic process for treating vacuum gas oils, residual feedstocks or mixtures thereof in the presence of up to 100 ppm of V and Ni at moderate hydrogen partial pressures. The process consists of two or more stages: (a) demetallization of feedstock to levels below 10 ppm of V and Ni, and (b) hydrodenitrogenation and hydroconversion of catalysts using a combined bed, and catalytic cracking of the 370.degree. C..+-. fraction to obtain gasolines. This process applies also to vacuum gas oils obtained from other processes, such as FCC, Flexicoque, etc.
