And the cata y tic crack ing reacts o f CGO, VGO, and VGO b ending w ith CGO w ere eva- uated. The resu ts show tha t com pared w ith conventiona FCC, under the sam e conve rsion, the y ie d of ight o i and iquid y ie d cou d be increased significant y, and the y ie d of dry gas cou d be reduced u sing TSRFCC techno ogy, w h ich exhibited exce en t advan tages in the cata y tic c racking o f CGO. Furtherm ore, on the w ho e the cata y tic cracking of CGO and VGO separate y w as superior to that o f VGO b ending w ith CGO. K ey words: wt o-stage r iser f u id cata y tic crack ing ;
