The Influence of Temperature to the Hydrotreating of Rapeseed Oil and Its Co-Processing with Middle Distillates

Original language description

The effect of varying temperature on the composition and properties of the products obtained from the hydrotreating of rapeseed oil and the co-processing of rapeseed oil, atmospheric gas oil and light cycle oil have been investigated. The effect on the obtained products from co-processing of feedstocks of varying rapeseed oil content was researched too. The physicochemical properties of the obtained products were also determined. Hydrotreating was performed in a tubular reactor with a co-current flow of raw material and hydrogen using sulphided Ni-Mo/Al2O3 catalyst. All samples were treated at a constant pressure (4 MPa), a constant weight hourly space velocity (WSHV) 2 h-1, a ratio of hydrogen to feedstock for the mixtures 350 m3·m-3 and for rapeseed oil 1000 m3·m-3 and at five different temperatures (340, 360, 380, 400 and 420 °C). Primarily, saturated hydrocarbons and by-products of methane, propane, CO, CO2 and water were formed, as the result of the rapeseed oil conversion. The products from the hydrotreating of rapeseed oil contained a small amount of polyaromatic hydrocarbons with this fraction increasing with the increasing temperature of hydrotreating. These products had good viscosities, high cetane indexes, insufficient densities and they contained trace amounts of sulphur. The products from co-processing contained less than 8 wt. % of polyaromatic hydrocarbons. This fraction also increased with increasing temperature and decreased with an increasing amount of rapeseed oil in the feedstock. The sulphur content in the products, that were obtained at temperatures of 380 °C and higher, met the standard ČSN EN 590. The physicochemical properties of all products from co-processing also met the standard.
