A process for the demetallization of hydrocarbon oils.

摘要

Hydrocarbon oils of which more than 70% by volume boils above 360 DEG C, which have a C5 asphaltene content of less than 2.5% by weight and of which the total vanadium and nickel content is 5-150 ppmw, are demetellized by contacting them at elevated temperature and pressure and in the presence of hydrogen with a catalyst containing as metal with hydrogenation activity exclusively molybdenum in a quantity of more than 2.0 parts by weight per 100 parts by weight of porous carrier, which catalyst has such an average pore diameter (p) and average particle diamter (d) that the relation: 7.0.10<-><3>.(PH2)<2> > p/d<0.5> > 1.4.10<-><3>.(PH2)<2>, where PH2 represents the hydrogen partial pressure used (p in nm, d in mm, PH2 in bar), is fulfilled.
