Industrial application of catalytic cracking catalyst LPC-65
The industrial application of LPC-65 catalyst was investigated in the 1.20 Mt·a-1 heavy oil catalytic cracking unit of Lanzhou Petrochemical Company of China Petroleum Corporation.The results showed that when the amount of LPC-65 catalyst added reached 50％of the system inventory,compared with the blank standard period,the conversion of heavy oil and gasoline yield increased by 1.24 and 0.62 percentage points,diesel yield decreased by 1.24 percentage points,gasoline olefins decreased by 4.09 percentage points,isomers and aromatics increased by 4.09 and 0.67 percentage points,respectively.After using the LPC-65 catalyst,the conversion capacity of heavy oil increased and the effect of reducing olefins in gasoline was significant.
