Abstract

The object of the present work is to develop the mathematical model of catalytic dewaxing of diesel oil cuts mixed with atmospheric gas oil. The considered process is aimed to produce com-ponents of diesel fuel with improved cold-flow properties. Thermodynamic and kinetic parameters of the model were determined, including changes in Gibbs free energy and rate constants of reactions. The model was validated with full-scale experimental data and presented a satisfactory correspondence with an absolute error of hydrocarbon groups content calculation does not exceeding 1.16 wt.%. Using the developed model the influence of industrial unit operational variables on unbranched long-chain paraffins conversion degree and the influence of raw materials composition on the yield of hydrocarbon groups were studied. The raw materials consumption and temperature optimization was performed for different raw materials compositions in order to obtain the best operating conditions for receiving diesel fuel components with improved cold-flow properties (cloud point -26oC, cold filter plugging point -28oC, pour point -35oC).
