Study on increase of yield of diesel fuel by catatytic cracking

Study on prolific diecsdel fuel by catalyst on minitype fixed fluied-bed,minitype contimous fluiedized bed and middle-sized lift leg.We probed theeffect on diesel fuel productivity and the rate of diesel fuel and gas oil of technologycal paramter,fed in different position in lift leg,and volued the new-type catalyst.The result indicted that it is good to prolific diesel fuel when the operation conditions were demulcent,but it need to work in with the catalyst that can transferm efficiently,low coking DMC-2 is one of the best catalyst.The selectivity crocking made the of productivity diecel oil highter 1.8%.
