Abstract

Recently, the issuing of more stringent specifications pertaining to several characteristics of modem base oils and the increasing demand for environmentally friendly fuel blending components (e.g. in the EU) have raised the interest of refining industries in hydroconversion processes of heavier feedstocks and longer chain normal paraffins to meet the market demand. These requirements and demands nowadays can be fulfilled practically only with the application of catalytic technologies. The main goals of our experiments were to select a catalytic system and to determine the advantageous process parameter combinations for the production of high quality base oils beside the production of modern fuel blending components with the hydrocracking of feedstock rich in n-paraffins (pour point: 50-54 °C, kinematical viscosity on 100 °C: 5.6 mm2/s, sulphur content: 15 mg/kg). The catalyst bed of the hydrogenating reactor contained Pt/SAPO-11 catalyst with enhanced acidity and NiMo/Al2O3 catalyst. The first catalyst helped the enaction of hydrocracking and isomerization reactions and the second catalyst was used for stabilizing the products of hydrocracking. Based on the results of the experiments carried out in a wide parameter range (temperature: 340-400 °C, pressure: 50-100 bar, LHSV: 0.75-3.0 h-1, hydrogen/hydrocarbon volume ratio: 500-1200) it can be concluded that base oils produced on advantageous process parameters had very good properties (viscosity index: 120-138, pour point: -10 (-) -16, low volatility and aromatic content), so they are suitable to produce environmentally friendly lube oils. The produced naphtha products have high isoparaffin (>70%) and low sulphur content (<2 mg/kg) and the gas oil products have high cetane number (62-65) and low sulphur content too (<3 mg/kg). These products can be applied as environmentally friendly fuel blending components.
