Abstract

The investigation of hydrodearomatization, hydrodenitrogenation and hydrodesulfurization of gas oils (up to 188 ppm sulfur, 193 ppm nitrogen and 38.4% total aromatic content) over Pd, Pt catalysts supported on USY zeolite, whose Pd/Pt mass ratio was varied between 6:1 and 1:3, and total metal contents were between 0.90 and 0.93, are presented. The effect of change of Pd/Pt ratio on HDA, HDN and HDS activities are demonstrated. The advantageous process parameters for HDA, HDN and HDS of gas oils over a selected catalyst (e.g. Pd/Pt mass ratio 2:1) were determined. Under optimum process parameters the conversion of polyaromatics was higher than 80%, that of nitrogen compounds higher than 89% and sulfur content of the obtained products was lower than 50 ppm in case of every applied feed.
