OB-3000催化剂在催化裂解装置上的应用

APPLICATION OF CB-3000 CATALYST IN DEEP CATALYTIC CRACKING UNIT

在催化裂解装置专用催化剂CIP II中掺入 8%～ 2 0 %OB 3 0 0 0催化剂 ,结果表明 ,平衡催化剂的活性由 67上升到 76,重油转化能力强 ,液化石油气收率及其丙烯含量变化不大 ,柴油收率下降了 2 .4个百分点 ,汽油收率上升了 1.3个百分点且汽油中烯烃加芳烃含量由 84%下降到 70 % ,干气和焦炭产率有所下降 ,平衡催化剂中 0～ 40μm细粉含量下降约

Blending DCC catalyst with 8%～20% of the OB 3000 catalyst,the activity of the equilibrium catalyst increased from 67 to 76,the conversion of heavy oil strengthened,the yield of LPG and its propylene content have slight variations,the yield of diesel decreased by 2.4 percent points,the yield of gasoline increased by 1.3 percent points and the content of olefins plus aromatics decreased from 84% to 70%,the yield of dry gas and coke have little decrease,the content of 0～40μm fine powder in equilibrium catalyst decreased by 9 percent points.
