摘　　要：采用轻油型加氢裂化催化剂体系,以高芳烃含量柴油为原料,进行加氢裂化中试试验,研究不同转化深度及不同切割方案对产品性质的影响。结果表明:在适宜的转化深度及馏程范围内,汽油的抗爆指数可达到87以上,是较好的汽油调合组分;柴油凝点可达到-30℃以下,可作为低凝柴油调合组分。以此数据建立六级总动力学模型,实现了对汽油抗爆指数及收率、柴油凝点及收率等的预测。通过预测值与试验值的对比,对模型参数进行调整,较好地预测了高芳烃含量柴油加氢裂化产品的性质,预测误差均在5%以内,对炼油厂的实际生产操作具有一定的借鉴意义。The pilot test of hydrocracking was carried out with light oil hydrocracking catalyst system and diesel oil with high aromatic hydrocarbon content as feedstock. The influence of different conversion depth and different cutting schemes on product properties was studied. The results showed that the antiknock index of gasoline could reach over 87 with the appropriate range of conversion depth and distillation range, which was a good blending component of gasoline. The condensation point of diesel oil could reach below-30 ℃, which could be used as blending component of low condensation point diesel oil. Based on the data, a six stage total kinetic model was established to predict the antiknock index and yield of gasoline, the condensation point and yield of diesel. By comparing the predicted value with the experimental value, the model parameters were adjusted to better predict the properties of diesel hydrocracking products with high aromatic hydrocarbon content, and the prediction errors were all within 5%, which had certain reference significance for the actual production operation of refineries.
