Nickel deactivators in high-temperature catalytic cracking of vacuum gas oils
Cracking of vacuum gas oils on microspherical zeolite-containing catalysts was studied in the 500-560degreesC temperature interval. The accumulation of nickel on the catalyst decreased the yield of the gasoline and diesel fractions. The antimony-containing deactivators were shown to diminish the poisoning effect of nickel on the catalyst.
