Experimental evaluation of vacuum gas oil-light cycle oil blends as FCC feedstock

In this work the effect of incorporating up to 12.8 vol % of light cycle oi l (LCO) in the conventional FCC feedstock was studied in a microactivity pl ant (MAT). The experimental work was carried out at typical operating condi tions (reaction temperature of 516 degreesC and catalyst-to-oil ratio of 5, 6, and 7). An equilibrium catalyst taken directly from,tbe circulating inv entory of an industrial catalytic cracking plant and real feedstocks were u sed in this study. A reduction-in conversion, gasoline and LPG; yields, and an increase in dry gas and coke yields were observed with the Increasing a mount of LCO in the feed. Gasoline RON also increases as the LCO content is increased in the FCC feedstock, The optimum amount bf LCO in the feed was found to be 7 vol %, which maximizes the valuable product production.
