摘要
通过改变灵活型催化剂床层的液时体积空速,同时采用提高灵活型催化剂床层反应温度的方法,保证了转化率。以加氢裂化催化剂的产品数学模型关联式为基础,对轻石正构烷烃含量、轻石异构烃加环烷烃含量、重石芳潜、喷气燃料芳烃、喷气燃料烟点、柴油凝点、柴油十六烷指数、柴油十六烷值、尾油BMCI(芳烃关联指数)值、尾油凝点等加氢裂化催化剂产品性质进行预测。通过试验值和拟合值的对比,发现试验值和拟合值间相互吻合得较好,预测误差均在5%以内,对加氢裂化催化剂实验产品性质的预测结果较好,在工业应用方面具有一定应用价值。
In this paper, LVSHs of different catalysts were obtained according to the mathematic correlations of flexible type catalyst and the x-lumping kinetic model. The conversion was guaranteed by increasing the temperature of cracking stage. Forecasts for the properties of hydrocracking products were realized such as paraffin content in light naphtha, content of isoparaffincycloparaffin in light naphtha, aromatics potential of heavy naphtha, smoke point aromatics of jet fuel, condensation point of diesel, cetane index of diesel, cetane number of diesel, condensation point of tail oil, BMCI of yail oil, and so on. Experimental value coincides with the fitted value. Product property was properly forecasted by readjusting some parameters. All the forecast errors are less than 5%, which makes it usable in industry.
