A Study of the Products of Alkylation of Turbine Oil Distillate with Catalytic Cracking Gases

Аннотация

The main physicochemical properties and structural parameters of the products of alkylation of the turbine oil distillate with catalytic cracking gases on Zeokar-600 and Omnikat-210P zeolite catalysts have been determined using IR, ¹H NMR, and UV spectroscopy techniques. Alkylation has been carried out in the temperature range of 50–150°C at oil : gas ratios of 1 : 1 and 1 : 2. The reaction products have been studied. The products have been obtained under optimal conditions, ensuring the maximum increase in the viscosity index of the oil fraction from 32 to 75 and 53 on the Zeokar-600 and Omnikat-210P catalysts, respectively. It has been shown that the kinematic viscosity and viscosity index of the oil fraction are increased by the alkylation. This is due to an increase in the length and quantity of alkyl substituents of aromatic hydrocarbons by adding propylene and butylene units of olefin hydrocarbon gases of catalytic cracking.
