Abstract:
1. A process of reducing the sulfur content of a catalytically cracked petroleum fraction, which comprises catalytically cracking a petroleum feed fraction containing organosulfur compounds at elevated temperature in the presence of a cracking catalyst and an additive to produce cracking products of reduced sulfur content, wherein the additive comprises a mixture of particulate of 5 to 30 wt. % of a Group VIB metal oxide and 2 to 10 wt. % of a Group VIII metal oxide; wherein the mixture of particulate is pulverized particulate having a particle size ranging from 1 nm to 900 nm; and wherein the cracking catalyst has a weight and the additive is present in an amount ranging from 1 to 25 weight percent of the weight of the cracking catalyst.
