EFFECT OF PARTIAL PRESSURE OF HYDROGEN SULPHIDE ON HYDROTREATING OF MIDDLE PETROLEUM DISTILLATES AND RAPESEED OIL BLEND

Popis výsledku v původním jazyce

Green diesel is currently produced by hydrotreating of pure bio-oils subsequently followed by hydroisomerization of n-alkanes to i-alkanes. It is also possible to produce green diesel by hydrotreating of a blended feedstock that is consisted of rapeseed oil and petroleum fractions typically used for production of diesel fuel. Rapeseed oil consists of triglycerides that are converted by hydrotreating to n-alkanes, propane, water, carbon dioxide and carbon monoxide. The aim of this work is to evaluate the effect of partial pressure of H2S on the catalyst activity and properties of the stabilized products of hydrotreating if the blended feedstock containing rapeseed oil was used. The blended feedstock was consisted of straight run gas oil, light cycle oil made by FCC, and rapeseed oil in a mass ratio of 66:17:17. The blended feedstock having sulphur content of 0.33 wt% was added by dimethyl disulphide (DMDS) in order to prepare two other samples for hydrotreating having sulphur content of 0.67 wt% and 1.01 wt%. Hydrotreating was carried out at temperatures of 320oC and 360oC and under a 4.0 MPa pressure. Commercial Co-Mo/Al2O3 + SiO2 hydrotreating catalyst was used. It was found out that desulphurization efficiency increased with increasing DMDS content although total sulphur of products also increased with increasing DMDS content The properties of hydrotreating products as aromatics content, density, viscosity and CFPP were dependent mainly on temperature of hydrotreating.
