    • An improved riser reactor containing a plurality of substantially vertically oriented venturis connected in series whereby the venturis have a maximum diameter, D.sub.1, and a minimum diameter, D.sub.2 ; and, apparatus for connecting the venturis end to end in which the cross-sectional area of the venturis at D.sub.1 is A.sub.1 and the cross sectional area at D.sub.2 is A.sub.2 and the ratio of A.sub.1 /A.sub.2 is between about 1.1 and about 113, preferably between about 2 and about 100, most preferably between about 5 and about 50. The present invention also includes a process for catalytic cracking of a liquid hydrocarbon feed by use of the riser reactor of this invention.
    • 一种改进的提升管反应器,其包含串联连接的多个基本垂直定向的通气孔,由此所述通风口具有最大直径D1和最小直径D2; 以及用于连接通风口端部到端部的装置,其中,在D1处的通风口的横截面积为A1,并且在D2处的横截面积为A2,并且A1 / A2的比率在约1.1至约113之间,优选地在 约2至约100,最优选约5至约50.本发明还包括通过使用本发明的提升管反应器催化裂化液体烃进料的方法。
