| 摘 要： | 以原位生长法制备了TiO2-SiO2与HY分子筛构成的重馏分油加氢精制催化剂复合载体Y/CTS，考察了HY分子筛的复合比例以及HY分子筛的柠檬酸预处理对复合载体理化性质的影响；以胜利焦化蜡油为原料，评价了NiW/Y/CTS催化剂的加氢精制性能。实验结果表明，Y/CTS复合载体具备较大的比表面积、孔容和孔径，以及一定的酸性分布。对HY分子筛进行酸预处理后，HY分子筛的酸量下降，但Y/CTS复合载体的酸性提高，表现为催化剂的加氢脱氮性能显著提高。

| Abstract: | Y-CTS and CY-CTS,a series of composite supports used for heavy oil hydrotreating catalysts,was prepared by in-situ growth method,in which CTS presented TiO2-SiO2 and Y presented HY zeolite and CY presented the HY zeolite pretreated by citric acid.The effect of the contents of HY zeolite in Y-CTS and CY in CY-CTS on the properties of Y-CTS and CY-CTS were studied.The hydrotreating performance of NiW/Y-CTS and NiW/CY-CTS were tested with Shengli coker gasoline(CGO) as feedstock.The results showed that Y-CTS possessed large specific surface,pore volume,pore diameter and a certain of acidity distribution.After treated with citric acid,the acidity amount of CY decreased compared to HY,while the acidity amount of CY-CTS increased compared to HY-CTS,then the hydrodenitrogenation(HDN) performance of NiW/CY-CTS improved remarkablely. |
