Hydrodeazotization and hydrogenation of aromatic compounds from petroleum cuts comprises use of catalyst containing platinum, supported on zirconium oxide

摘要

The catalyst used in the hydrodeasotization and hydrogenation of aromatic compounds from petroleum cuts has a high resistance to sulfur- and nitrogen-containing compounds. The deazotization and hydrogenation of petroleum aromatic cuts with a boiling range of 90-500 deg C, contaminated by nitrogen contents of 1-1000 ppm and sulfur contents of 1-1000 ppm and having an aromatic content of 5-70% comprises contacting with hydrogen in the presence of a catalyst comprising a zirconia (ZrO2) support impregnated with 0.1-2% platinum (Pt). Independent claims are also included for the preparation of the catalyst and its use.
