摘要
为满足市场对清洁燃料油及化工原料需求量不断增长的要求,中国石油化工股份有限公司抚顺石油化工研究院以无定型硅铝为主载体,改性Y型分子筛为主要酸性组分,W-Ni为活性组分,采用浸渍法制备了FC-50中油型加氢裂化催化剂,属多产中间馏分油兼产高质量重石脑油和尾油的催化剂。在试验装置上对该剂与国内同类先进催化剂进行了对比评价,并进行了工业放大。结果表明,FC-50催化剂具有较高的中间馏分油选择性、反应活性以及良好的稳定性,产品质量优良。以伊朗VGO-1为原料,使用FC-50催化剂,在反应温度380℃、空速1.5h-1条件下,单程转化率为65.8%,中间馏分油选择性79.90%。在相同条件下,FC-50与FC-26催化剂相比,反应温度低3℃,中油选择性比FC-26催化剂高近2%。结果表明,FC-50催化剂的反应性能完全达到了实验室定型催化剂的水平。
To meet the increasing market demand for clean fuel and feedstock for chemical production, FRIPP has developed FC-50 hydrocracking catalysts for high middle distillates, which were prepared by impregnation and by using amorphous silica-alumina as the main carrier, a modified Y zeolite as the main acidic components, and W-Ni as hydrogenation component. The comparison evaluation test with a same type domestic advanced catalyst was carried out and commercial scale-up was performed. The evaluation results indicated that the FC-50 catalyst had a higher middle distillate selectivity, good reaction activity, good stability and excellent product quality. When VGO-1 from Iranian crude was used as the feed and FC-50 catalyst as the reaction catalyst, the single-pass conversion was 65.8% and middle distillate selectivity was 79.90% at operating conditions of 380 ℃ reaction temperature and 1.5 h^-1 space velocity. Under the same conditions, as compared with the FC-26 catalyst, the reaction temperature of FC-50 catalyst was 3 ℃ lower and middle distillate selectivity was about 2% higher. The commercial scale-up tests demonstrated that the reaction performances of the FC-50 catalyst have completely reached the performance level of laboratory catalyst.
