在本模型中，煤的所有反应都假定为不可逆的一级反应。加氢裂化步骤假定为一级或零级。基于上述反应机理，从实验和理论两方面考察了（a）料浆空间时间、（B）反应器温度、（c）反应器压力、（d）初始煤浓度和（e）气体流速对产物分布的影响。淤浆空间时间和反应温度被发现对CCL产品分布有显着的影响。在所考虑的范围内，反应器压力、进料煤浓度和气体流量似乎对产物分布具有相对温和的影响。
In the present model all reactions from coal are assumed to be irreversible and first order. The hydrocracking steps are assumed to be either first or zero order. Based on the aforementioned reaction mechanism, the effects of (a) slurry space time,(b) reactor temperature,(c) reactor pressure,(d) initial coal concentration, and (e) gas flow rate on the product distributions are examined both experimentally as well as theoretically. Slurry space time and the reaction temperature are found to have a pronounced effect on the CCL product distribution. Over the ranges considered, reactor pressure, feed coal concentration, and the gas flow appeared to have relatively mild effect on the product distribution.
