The cold model test data showed that the fluid distribution performance of the novel vapor-liquid distributor was evidently better than the traditional one. Com- mercial tests of the new distributor were carded out in the 300 kt/a gas oil hydrotreating reactor at SINOPEC Changling Branch Company, showing that the new vapor-liquid distributor could improve the fluid distribution, promote the hydrotreating efficiency and lead to better performance than the traditional one.展开更多

The commercial testresults indicate that the olefin content of catalyti-cally cracked gasoline can be significantlyreduced to less than 20 v%, while sulfur content reduced by 15%-25% and RON increased by 0.5―2units in a RFCC unit. In addition, propylene yield and the production ratio of diesel to gasolinecan also be remarkably enhanced in the RFCC unit.展开更多
