Abstract

In the laboratory tests of combination process of denitrification refining and fluid catalytic cracking , a specially developed acidic chelating agent is used for denitrification refining. This agent can selectively remove basic nitrogen compounds from coker gas oil and the refined oil yield is over 97%. The test demonstrates that, at given conditions, the FCCU exhibits a significant difference in product yields with refined and un-refined feeds. With the refined coker gas oil feed, the total yield of FCC LPG, gasoline and LCO is 10% higher than that of un-refined feed. When FCC feed stream contains 25% of coker gas oil and 75% of straight-run gas oil, the mix feed with refined coker gas oil offers 4% advantage in the total yield of FCC LPG, gasoline and LCO over mix feed with un-refined coker gas oil.
