Characterization and commercial application of LB-2 catalyst for processing heavy oil

A novel REHY type FCC catalyst LB-2 for processing heavy oil was prepared from kaolin by in situ crystallization, its molecular sieve content was ∼ 30% and the pore diameters were mainly concentrated in the range of 300-1000 nm. In comparison with the reference metal tolerance catalysts, the activity, naphtha yield, and coke selectivity of LB-2 were better at vanadium and nickel depositions of 5000 and 3000 μg/g, respectively. The commercial application showed that the liquid yield of LB-2 was higher than that of the original catalyst, the naphtha yield was 2% higher and the octane number was obviously improved.
