| Summary: | Title screen 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 thermosdynamic 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 nonstationarymathematical model of the catalytic dewaxing process. The mechanism of bifunctional dewaxing catalyst deactivation was described. With the non-stationary mathematical model, the forecast accuracy and optimizing calculations of the dewaxing process temperature mode were carried out depending on the feed composition and catalyst activity. |
