Abstract Based on the physico-chemical regularities, the unsteady mathematical model of the diesel fuel catalytic dewaxing process was developed. The influence of the raw materials composition and flow rate on the catalyst deactivation degree, product output and cold filter plugging point was shown. It was established, that while producing low-freezing diesel fuel, the higher the aromatic content in the raw materials, the higher the catalyst deactivation degree. An increase in the raw materials flow rate leads to a decrease in the catalyst deactivation degree, an increase in the product output and deterioration of the cold filter plugging point.

基于非稳态数学模型的柴油催化脱蜡过程研究

摘要 根据物理化学规律，建立了柴油催化脱蜡过程的非稳态数学模型。显示了原料组成和流量对催化剂失活程度、产物产量和冷滤堵塞点的影响。确定在生产低凝柴油的同时，原料中芳烃含量越高，催化剂失活程度越高。原料流量的增加导致催化剂失活程度降低，产品产量增加，冷滤堵塞点变差。
