Summary:Title screen
The chemistry of the diesel oil fractions isodewaxing process on the catalysts containing noble metals (Pt, Pd) was studied. The process of isodewaxing is intended for the production of diesel fuel with improved cold-flow properties, corresponding to the winter and arctic grades. The thermodynamic parameters of the reactions were determined. The mechanisms of coke formation on the catalyst surface were studied. A scheme of chemical transformations was devel-oped, taking into account target and side reactions, as well as the mechanisms of coke formation. Based on the identi-fied patterns, a mathematical model of the process was developed. The model is sensitive to the composition of the pro-cessed feedstock and can be used to predict the cold filter plugging point, the yield of low-freezing diesel fuel, and the catalyst activity in the isodewaxing process. Using the developed model, predictive calculations of the cold filter plug-ging point and the yield of low-freezing diesel fuel, as well as predictive calculations of the decrease in catalyst activity during the processing of raw materials of various compositions, were carried out. Hydrotreated and unhydrotreated diesel fractions were considered as the raw materials. The effect of the hydrogen-containing gas consumption on the activity of the catalyst was shown.
