Název v původním jazyce

Hydrotreating of middle petroleum distillates and rapeseed oil blend over Ni-Mo catalyst

Popis výsledku v původním jazyce

Hydrotreating of feedstock consisting of 90 wt% of straight run gas oil and 10 wt% of light cycle oil, which are used for diesel fuel production, with addition of rapeseed oil in amount of 0, 5, 10, 15 or 20 wt% was studied. Hydrotreating of the feedstocks was carried out in a laboratory flow reactor using Ni-Mo/Al2O3 catalyst at a temperature of 345 oC, under a pressure of 4.0 and 8.0 MPa, WHSV of 1.0 h-1 and hydrogen to feedstock ratio of 230 m3BULLET OPERATORm-3. It was found that the dominant products of rapeseed oil conversion were C17 and C18 n-alkanes, as expected. All liquid products met EU diesel fuel specification for sulphur content (<10 mgBULLET OPERATORkg-1). The content of aromatics was very low due to high hydrogenation activity of the catalyst and total conversion of rapeseed oil into saturated hydrocarbons. Addition of depressant did not affect the cold filter plugging point of the products. Larger amount of n-C17 than n-C18 alkanes suggested that hydrodecarboxylation and hydrodecarbonylation reactions took place preferentially than hydrodeoxygenation one.
