Alkylation of the turbine oil’s distillate fraction with C3-C4 olefins
A.I. GuliyevThe paper presents the results of improving the viscosity index of the distillate fraction of turbine oil during its alkylation with liquefied catalytic cracking gases on the Цеокар-600 and Омникат 210 П catalysts. It was shown that during the alkylation process at 50 °C temperature, 0.6 MPa pressure and an oil-gas ratio of 1:1÷2, the viscosity index of the turbine oil’s distillate fraction increases from 32 to 80–81 on the Цеокар-600 catalyst and to 66 at 150 °C temperature, 0.6 MPa pressure and an oil-gas ratio of 1:1 on the Омникат 210П catalyst. The conversion of C3-C4 olefins in the alkylation process on Цеокар-600 in these conditions was 81.8–85.2 %. The Цеокар-600 catalyst showed higher activity in comparison with Омникат 210П, as the viscosity index increase was 20 points higher.
