摘要: 以辽化加氢裂化尾油为原料评价自制的非临氢降凝催化剂FC-DB的使用性能,考察反应温度与空速对基础油收率及凝点的影响,采用多元二次回归方程式回归出基础油收率及凝点与操作条件的关系,用非线性规[CM(49*3]划的方法确定出实验范围内适宜的操作条件,即反应温度为400[KG*3]℃,空速为1.2[KG*3]h-1,在该条件下,基础油收率为[CM)]92.53%,凝点为-20 ℃,下降幅度近53 ℃。并对该操作条件下得到的基础油进行全质分析,结果表明,加氢裂化尾油经非临氢降凝得到的基础油,粘度指数高,酸值、残炭低,是优质的润滑油基础油。

Abstract: The catalytic performance of self- developed non-hydrogen-dewaxing catalyst (FC-DB) was evaluated, and the hydrocracking tail oil was used as feed stock. The influence of reaction temperature and space velocity on the yield and pouring point of base oil was investigated. The relationships between yield, pouring point and operation conditions were determined by polynary quadratic regression, and the optimum operation conditions were determined by non-linear programming. The reaction temperature is 400 ℃ and space velocity is 1.2 h-1. At this time, the yield and pouring point of base oil respectively are 92.53% and -20 ℃, approximately dropping 53 ℃. The qualify of base oil obtained under above optimum operation conditions was analyzed, and the base oil can be used as premium lubricant base oil because of its high viscosity index, low pouring point, acidity and residue carbon.
