摘　　要：采用MIP-DCR催化裂化工艺技术,利用LPEC专利设备—预提升混合器,降低了再生催化剂和原料油的接触温度差。在原料性质相当的情况下,两套装置干气收率分别下降了33.41%和23.84%,焦炭收率分别下降了7.16%和2.39%,轻油收率分别上升了2.97%和2.35%。同时,气体产品的裂化机理比例(CMR值)表明,MIP-DCR技术可以减少催化裂化反应过程引发中的单分子质子化裂化反应和热裂化反应的比例和选择性,从而最终实现在基本相同的反应深度下,降低干气和焦炭的产率来提高产品总液收,达到从石油资源中获取更多高价值产品的目的。TheMIP-DCR catalytic cracking technology and LPEC patent equipment - lifting mixer were used to decrease the contact temperature of oil and catalyst in two sets of catalytic cracking units. The results showed that, under the similar operating condition, the yield of dry gas decreased by 33.41% and 23.84%, respectively, the yield of coke decreased by 7.16% and 2.39%, respectively, and the yield of light liquid increased by 2.44% and 1.86%, respectively. Cracking Mechanism Ratio（CMR） of gas products showed that MIP-DCR technology could reduce the single molecule protons in the catalytic cracking reaction process, ultimately reduce the yield of dry gas and coke, increase total liquid product, and obtain more high value products from the oil resources.
