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.
