Oxidative oligomerization of a synthetic fraction of hydrocarbons from the Fischer-Tropsch synthesis
https://doi.org/10.18412/1816-0387-2025-1-66-73
Abstract
The work investigated the process of oxidative oligomerization of Fischer-Tropsch synthesis products - a fraction of C10-C15 hydrocarbons with a total content of alkenes (mainly β- and γ-alkenes) of 64.7 wt. % using zirconium octoate as a catalyst. The hydrocarbon fraction was obtained on a zeolite-containing catalyst at a pressure of 2.0 MPa, a temperature of 250 °C, H2/CO ratio at the reactor inlet of 1.70, a gas space velocity of 1000 h-1 and circulation mode ratio range 0-16. It was found that at a temperature of 160 °C the catalyst content is 5.0 wt. %, process duration 6 hours and pressure (air) - 2.5 MPa, target fraction yield - 52.7 %. It was found that the oligomerization product has a low pour point of minus 31 °C. It was proposed to improve the viscosity characteristics of the oligomerization product by introducing additives into its composition, for example, polymethacrylates or polyisobutylene.
