Industrial application of CTP technology catalyst LPS-67D for low carbon olefins in catalytic cracking unit of Daqing Hongwei Qinghua
Based on transforming from producing refined oil products to producing chemical materials of oil refineries in China,PetroChina Petrochemical Research Institute developed the CTP technology for increasing low-carbon olefins production through catalytic cracking process.And LPS-67D catalyst for CTP technology was developed to satisfy the technical needs of increasing the yield of low-carbon olefins at the 500 kt·a-1 heavy oil catalytic cracking unit of Daqing Hongwei Qinghua.The industrial application results of LPS-67D catalyst in this catalytic cracking unit demonstrated that under the similar catalytic raw materials and process conditions excellent catalytic cracking performance for stimulating low-carbon olefins production was achieved by using LPS-67D catalyst.And compared with the contrasted catalyst,in case of the premise of ensuring the stability of the device and the similar product distribution,the propylene(based on heavy oil)yield increased by 1.57 percentage points;the liquefied petroleum gas yield increased by 2.23 percentage points;the diesel oil yield decreased by 2.52 percentage points and the total liquid yield increased by 0.99 percentage points.These results indicate that LPS-67D catalyst reaches the target of application.
