Diesel Fraction Hydrotreating in the Presence of Nickel–Tungsten Sulfide Catalyst Particles In Situ Synthesized in Pores of Aromatic Polymers
A catalyst based on mixed nickel and tungsten sulfides has been synthesized by the decomposition of the thiosalt [N(n-Bu)4]2[Ni(WS4)2] in pores of a polymer matrix, namely, mesoporous aromatic framework PAF-FC-1. The catalyst has been tested in diesel oil fraction hydrotreating at a hydrogen pressure of 5 MPa and a temperature of 380°C. Reaction products have been analyzed by two-dimensional gas chromatography using a time-of-flight mass detector and a flame ionization detector. It has been shown that the use of the synthesized catalyst provides a decrease in the content of bi- and polycyclic hydrocarbons and a significant decrease in the sulfur compound concentration in oil fractions.
