The 280-330℃ aromatic extract from catalytic cracking gas oil was hydrofined over the Mo-Ni and Mo-Ni-P commercial hydrofining catalyst under the operation conditions of hydrogen partial pressure 60kg/cm~2, reaction temperature 360℃, oil feed rate (LHSV) 1.0 vol/vol/hr and hydrogen charge ratio l,000vol/vol of oil. The hydrofined product was fractionated into two fractions of 240-310℃ and 310-365℃. Heat stability test showed that the heat stability of the former was comparable to to Dotherm (diphenyl-diphenyl oxide), and that of the latter to France Gilotherm T H(hydrofining diphenylbenzene).

As the proportion of catalytic cracking oil is raised, the density of blend of oil is increased and an experimental relation is given. Meanwhile, the centane number and calorific power are reduced. Viscosity, however,has a little change. The vaporization characteristic of blend oil is satisfactory for diesel engine. The ignition delay, maximum cylinder pressure and emission of NO and HC are rais- ed. In addition, the fuel consumption is increased because the calorific power of blend oil is less than that of...

As the proportion of catalytic cracking oil is raised, the density of blend of oil is increased and an experimental relation is given. Meanwhile, the centane number and calorific power are reduced. Viscosity, however,has a little change. The vaporization characteristic of blend oil is satisfactory for diesel engine. The ignition delay, maximum cylinder pressure and emission of NO and HC are rais- ed. In addition, the fuel consumption is increased because the calorific power of blend oil is less than that of conventional oil. The above feature may be adapted to diesel engine when the proportion of catalytic cracking oil is less than 40 pe- rsent.

广州石油化工总厂催化裂化柴油加氢精制装置一次开车成功,并取得比较满意的结果,产品质量优良,装置处理能力超过设计值。分别于1987年5月和8月用胜利催化裂化柴油进行了两次标定,标定结果表明,RN-1催化剂具有良好的加氢精制性能。在低压、低温(氢分压2.9MPa,空速2.0h~(-1),反应器入口温度270℃,反应器床层平均温度286℃,氢油比351—518)的缓和条件下,精制柴油的产品质量可以达到赶超标准。在此条件下,氢耗量59.4Nm~3/t 原料,能耗686.7MJ/t 原料(16.48×10~4kcal/t 原料),远远低于设计值。在氢分压2.9MPa,空速1.5h~(-1),反应器入口温度303℃,反应器床层平均温度330℃,氢油比693的条件下,脱氢率达76.2%,脱碱氮率达93.4%,脱硫率达94.3%,体现了RN-1催化剂脱氮活性高的特点。
