    The effect of pressure on hydrotreating of rapeseed oil

  • Original language description

    The main reason for production and application of biofuels is environment protection. Biomass containing triglycerides (i.e. vegetable oils, animal fats, used cooking oils and oils from microalgae) constitute a very attractive feedstock due to its favourable composition. At present, these feedstocks are processed mainly by transesterification (biodiesel production) and seldom by hydrotreating. When hydrotreating is used, product with a better thermo-oxidative stability and higher energy content is obtained in comparison with biodiesel. Hydrotreating of vegetable oils is usually carried out at temperatures of 300 ? 370 °C and pressures of 2 ? 10 MPa. Sulfidic (mainly Ni-Mo, Co-Mo and Ni-W) or metal (Pt, Pd, Ni) catalysts supported on alumina are commonly used. In this work, the influence of reaction temperature and pressure on the composition and properties of products from hydrotreating of rapeseed oil was evaluated. A sulfidic Ni-Mo/?-Al2O3 catalyst, temperatures of 260, 280 and 300 °C and pressures of 0.5, 1, 2, 4 and 8 MPa were used. Obtained results showed that a complete conversion of rapeseed oil into hydrocarbons was achieved only at the highest tested temperature. The content of unreacted triglycerides in products decreased with increasing reaction temperature and pressure as expected. The content of oxygen-containing intermediates in products (palmitic and stearic acid, octadecan-1-ol) was the highest at 280 °C. Hydrodeoxygenation was preferred at the expense of hydrodecarbonylation/hydrodecarboxylation at higher pressures, which was evident from the decreasing C17/C18 hydrocarbons ratio with increasing hydrogen pressure.
