Study of the catalyst ZSM-5, modified Zr, for the alkylation process of oil distillate fractions

Keywords. ZSM-5, modified zeolite ZSM-5-ZrO₂, Х-RAY diffraction, phase composition, alkylation, viscosity index.

Abstract. X-ray diffraction studies of zeolite ZSM-5, zirconyl chloride modifier ZrOCl₂∙6H₂O and modified zeolite ZSM-5-ZrO₂ calcined at temperatures of 200, 400 and 550^o С were carried out. It has been determined that the phase composition of samples of the modified ZSM-5-ZrO₂ zeolite varies depending on the calcination temperature. An increase in temperature from 200 to 550°C promotes the transition of the amorphous phase to the crystalline one. The crystal structure of the ZSM-5-ZrO2 catalyst calcined at 550°C contributes to an increase in its activity, as a result of which, during alkylation with catalytic cracking gases, the viscosity-temperature properties of the distillate fraction of T-30 turbine oil are significantly improved (viscosity index increases from 49.9 to 150).
