焦化汽油的催化裂化改质

报道焦化汽油催化裂化改质的工业试验结果，将11％－15％的焦化气油注入提升管预提升段与胜利管输VGO，CGO和VR混炼，经催化改质后，辛烷值可以达到90号汽油指标的要求,并可获得满意的产品分布，同时催化汽油的改质可明显降低催化汽油的烯烃含量，为焦化汽油利用找到了一条经济可行的途径。

UPGRADING COKER NAPHTHA IN FCC UNIT

The results of commercial trial for upgrading coker naphtha in FCC unit were presented. Coker naphtha was introduced to the pre riser of FCCU and catalytic cracked with a mixture of Shengli VGO/CGO/VR feedstock. The percentage of the coker naphtha in the FCC feedstock was 11 to 15. The result indicated that the RON of the cracked naphta reached the requirement of 90# gasoline and the product distribution was promising. Blending coker naphtha in FCC feedstock could reduce the olefin content of the product naphtha, which was a feasible way for upgrading coker naphtha.
