Domestic technology developments on high-efficiency heavy oil conversion FCC catalysts’ industrialization

Abstract

The article introduces industrialization status of the following products developed by Lanzhou Petrochemical Company, CNPC: olefin reduction catalyst (LBO and LDO series) and LBO-A additive; propylene maximizing catalyst (LCC-1) and additive LCC-A; heavy oil conversion FCC catalyst LHO-1 and LB series; high octane number FCC catalyst (LOG and LDC series). When LBO-12 catalyst reach 66 % of the system inventory, the gasoline olefin yield decreases 9.1 %; When LBO-16 catalyst reach 50 % of the system inventory, the gasoline olefin yield decreases by 10 %; LBO-16 catalyst’s application shows that the diesel yield maintains the same. When LBO-A reaches 15 % of system inventory, the gasoline RON has increased by 0.6 units and gasoline olefin yield decreased by 3.3 %. The standardization on LDO-75 catalyst after its system inventory reaches 80 % shows that the light oil yield and total liquid yield have increased 1.37 and 0.54 %, respectively; After adopting LCC-2 catalyst and compared to 0 % case scenario, the propylene yield increases by 1.01 %. When LCC-A reaches 6 % of system inventory, the propylene yield increases by 1.41 % and RON by 1.5 units; the total liquid yield increases by 1.44 % and slurry yield drops by 1.41 % after LHO-1 catalyst reaches 80 % of system inventory; LDC-200 catalyst’s application shows 1.77 % total liquid yield increase, 0.83 % light oil yield increase and 1.72 % increase on propylene selectivity. The gasoline RON also increases 1.5 units; by adopting TMP technology and its matching catalyst LCC-300, propylene yield in product distribution reached as high as 20.38 %; When MIP process matching catalyst LIP-100’s system inventory reached 100 %, LPG’s yield increased by 1.04 %, gasoline yield increased by 0.74 %; The comparison of results between end-term and blank case standardization of MIP-CGP process matching catalyst LDR-100 shows 0.4 wt% increase in diesel yield, 3.52 wt% increase in LPG yield and 1.3 units on gasoline RON.
