The improvement of catalytic dewaxing reactor model for the production of diesel fuel was arranged. The formalized scheme of the reactions proceeding in the reactor was advanced by applying the results of thermodynamic calculations in the Gaussian software package. The occurrence of such important reactions as paraffin cracking and olefin cyclization was defined. The improved reaction network allowed developing the kinetic model of the reactor with a heat balance for predicting reactor outlet temperature depending on the feedstock composition. The results of forecasting calculations showed that optimal temperatures for production of diesel fuel with the pour point temperature of -35°C and cloud point temperature of -26°C range within 357-369°C depending on the feed composition. In this case, it is likely to obtain the yield of product equal to 95-98 %. Model predictions of reactor temperature drop, low-temperature properties and volume of diesel fraction obtained match closely the plant data.
