摘要在减压渣油加氢裂化实验的基础上，采用集总模型对催化反应进行了动力学研究。集总物质是渣油（798 K+）馏分中的饱和物、芳烃、树脂和沥青质（SARA）组分以及产物中的气体、石脑油、煤油、瓦斯油、减压瓦斯油和焦炭。黄铁矿反应有利于加氢裂化轻产品是更多的温度依赖性比使用黄铁矿和活性炭的混合物。动力学研究表明，活性炭的加入限制了胶质向沥青质的转化。
Abstract Based on the experimental hydrocracking of vacuum residue, a kinetic study using a lumping model was carried out to gain insight into the characteristics of catalytic reactions. The lumped species were the saturates, aromatics, resins, and asphaltenes (SARA) constituents in the residue (798 K+) fraction and gas, naphtha, kerosene, gas oil, vacuum gas oil, and coke in the products. The pyrite reaction favoring hydrocracking to lighter products was more temperature-dependent than that using a mixture of pyrite and active carbon. The kinetic study showed that the addition of active carbon to pyrite limited the transformation of resins to asphaltenes.
