Abstract
Hydrorefining of a hydrocarbon charge of high metal content with a catalyst containing alumina, a metal from group VI and a metal from the iron group, of a specific surface from 120 to 200 m.sup.2 /g, a total pore volume from 0.8 to 1.2 cc/g and a pore distribution as follows: PA1 0 to 10% of pores smaller than 100 A PA1 35 to 60% of pores from 100 to 600 A PA1 35 to 55% of pores greater than 600 A, including 10 to 25% of pores greater than 10,000 A, said catalyst optionally containing additionally an alkaline-earth metal.
