Abstract

The aim of our experiments was to investigate the applicability of an expediently modified NiMoW/Al2O3 catalyst for the conversion of specially pretreated Hungarian sunflower oil with high oleic acid (>90%) content which was ennobled for our experiments to produce motor fuels. The changes of the specific hydrocracking activity of the applied catalyst, the pathways of hydrodeoxygenation reactions and the effect of the process parameters on the yield and on the quality of the products were also investigated. It was concluded that on the investigated modified NiMoW/Al 2O3 catalyst products with high (>70%) paraffin content (T = 340-360 °C, p = 20-40 bar, LHSV = 1.0-1.5 h-1, H 2/sunflower oil volume ratio: 600 Nm3/m3) could be produced. In case of every investigated process parameter the C 17- and C18- paraffins were formed, i.e. on the applied catalyst both the HDO and the decarboxylation/decarbonylation (DECARB) reactions took place as a function of the process parameters. The gas oil boiling range target products had significantly higher isoparaffin-content than other transition metal/support catalysts derived products. Therefore the best quality product mixtures had large cetane number (71-76) and favorable CFPP value.
