### Abstract

This paper considers the process of catalytic dewaxing of petroleum derived middle distillates on the bifunctional Ni-based catalyst. The process is aimed at production of low-freezing, low-sulfur diesel fuels suitable for application in cold weather conditions. The method of mathematical modelling is applied in the current research. The mathematical model was developed taking into account thermos-dynamic and kinetic laws of the dewaxing process as well as factors influencing catalyst deactivation. The model is sensitive to the feedstock composition and technological conditions change in a wide range. The dewaxing catalyst deactivation degree was estimated using the operational data of the industrial catalytic dewaxing unit, and the calculations were conducted with the developed non-stationary mathematical model of the catalytic dewaxing process. The mechanism of bifunctional dewaxing catalyst deactivation was described. With the non-stationary mathematical model, the fore-cast accuracy and optimizing calculations of the dewaxing process temperature mode were carried out depending on the feed composition and catalyst activity.
