The FCC yield structure of vacuum gas oil, blended with varying amounts of coker gas oil or resid, can be significantly improved by hydrotreating prior to fluid catalytic cracking. Nearly a 10% increase in conversion can be realized by pretreating. Another advantage is the improved selectivity to desired products. Pilot plant data has been obtained on vacuum gas oil as well as blends of coker gas oil/vacuum gas oil and resid/vacuum gas oil. These FCC feedstocks were hydrotreated over commercially available Ketjenfine nickel-moly catalysts. FCC characteristics of these oil feeds and the hydrotreated products were studied on a Micro Activity Test (MAT) unit with commercial Ketjen Cat FCC catalysts. Data from the FCC tests clearly show the increased conversion and improved selectivity realized by hydrotreating. The results of these studies translate into increased profitability for the refiner.
