中文摘要：
对煤液化产物进行溶剂的分级处理,采用集总的方法得到Ni-Mo-S/Al2O3催化神府煤液化动力学模型。该模型包括了煤、前沥青烯、沥青烯和油气之间的相互转化,考虑了连串反应、平行反应和逆向转化以及结焦反应的影响,可以较好地模拟Ni-Mo-S/Al2O3催化神府煤液化过程。基于建立的Ni-Mo-S/Al2O3催化神府煤的动力学模型,求得神府煤催化液化的表观活化能为125-244 kJ/mol。通过对计算得到的模型参数分析表明,在高温阶段存在明显的油气向沥青烯以及沥青烯向前沥青烯的逆向转化。当温度高于420℃时,出现前沥青烯和沥青烯结焦反应现象。
英文摘要：
A kinetic model for Shenfu （SF） coal liquefaction catalyzed by Ni-Mo-S/A12 03 was built by using lumped kinetic method, where the liquefaction products were fractioned by solvents. The model has considered the mutual transformations among coal, preasphaltene （PA）, asphaltene （AS） and oil in the process, in which a series of consecutive, parallel, regressive and coking reactions were integrated. The results showed that the process of SF coal liquefaction catalyzed by Ni-Mo-S/Al2O3 can be well simulated by the model; based on this kinetic model, the activation energy of SF coal liquefaction is 125 - 244 kJ/mol. There exist obviously regressive reactions of oil and gas to AS and AS to PA at high liquefaction temperature. Moreover, the coking reactions of AS and PA to coke may take place when the liquefaction temperature exceeds 420 ℃.
