Method and device for descending catalytic cracking by injecting feedstock at an adequate angle

本发明通过以气体和液体(即液体烃与含氢气体的混合物)的交替环的形式以不足以流化催化剂床层的速度导入流体使均匀分布的氢与烃进料基本上连续地流过密集填充催化剂床层以便基本上充填反应器的整体。催化剂的密度、形状和粒径在设定进料速度下流化。进料的液气组分在整个床层面积上的交替环中进入床层。 PCT No. PCT/FR97/01630 Sec. 371 Date Aug. 19, 1998 Sec. 102(e) Date Aug. 19, 1998 PCT Filed Sep. 16, 1997 PCT Pub.

Zusammenfassung:	本发明通过以气体和液体(即液体烃与含氢气体的混合物)的交替环的形式以不足以流化催化剂床层的速度导入流体使均匀分布的氢与烃进料基本上连续地流过密集填充催化剂床层以便基本上充填反应器的整体。催化剂的密度、形状和粒径在设定进料速度下流化。进料的液气组分在整个床层面积上的交替环中进入床层。 PCT No. PCT/FR97/01630 Sec. 371 Date Aug. 19, 1998 Sec. 102(e) Date Aug. 19, 1998 PCT Filed Sep. 16, 1997 PCT Pub. No. WO98/12280 PCT Pub. Date Mar. 26, 1998A process is described for catalytic cracking of a petroleum feed in which a catalyst from a regeneration zone 4 is caused to flow in a dense fluidized bed conditioning zone 2 upstream of an injection zone 10, the fluidization rate being 0.1 to 30 cm/s. The throughput of catalyst into injection zone 10 is regulated by a constriction means 11. The hydrocarbon feed 12 is injected below the constriction means and flows counter-current to the direction of flow of the shaped catalyst flow. The hydrocarbon feed 12 is injected at a set injection angle depending on the movement of the feed and the catalyst.
