高掺炼焦化蜡油催化裂化催化剂的工业应用

介绍了高掺炼焦化蜡油催化裂化催化剂LDO-70 C在中国石油乌鲁木齐石化公司1.40 Mt/a催化裂化装置上的工业应用情况.结果表明:与空白标定相比,在焦化蜡油掺炼比(质量分数)由25％提高至30％的条件下,液化气、汽油、总液体收率分别增加了0.30,2.86,1.50个百分点,干气、焦炭、柴油收率分别降低了0.06,...

Industrtial application of fluid catalytic cracking catalyst for high coker gas oil blending ratio

The industrial application of fluid catalytic cracking(FCC)catalyst LDO-70 C for high coker gas oil blending ratio in 1.40 Mt/a FCC unit of Wulumuqi Petrochemical Company,PetroChina,was introduced.The results showed that compared with the blank calibration,under the condition of coker gas oil blending ratio increased from 25%to 30%(mass fraction),the yields of liquefied petroleum gas,gasoline and total liquid had increased by 0.30,2.86,1.50 percent points,while the dry gas,coke and diesel yields had decreased by 0.06,0.51,1.67 percent points.The volume fraction of saturated hydrocarbon gas in gasoline had been reduced by 2.1 percent points,the volume fraction of olefin and aromatic had increased by 0.5 and 1.6 percentage,research octane number had increased by 0.4 units;cetane value of diesel had no significant chang;and the volume fraction of propylene in liquefied petroleum gas had increased by 1.3 percent points.
