SETT ATT HYDROKATALYTISKT AVMETALLISERA KOLVETEOLJOR MED EN TOTAL VANADIN- OCH NICKELHALT AV MER EN 500 PPM

摘要

K 5345 Hydrocarbon oils with a total vanadium and nickel content above 500 ppmw are demetallized by contacting them at elevated temperature and pressure and in the presence of hydrogen with a non-promoted catalyst which meets certain given requirements with respect to porosity and particle size.
