Review
The effects of promoters, active metals and catalyst support material on deoxygenation of rapeseed oil were investigated. At 250 and 270 °C and various flow rates (W/F = 0.25, 0.50, 1.00 h), Ni-promoted catalysts were found more active than Co-promoted ones. NiMo catalyst was found as the most active metal combination, while CoW was the least active one. High selectivity for hydrodeoxygenation reaction pathway (total hydrogenation) was observed for CoMo type catalysts. Co addition into NiMo type catalyst resulted in conversion decrease, nevertheless selectivity was not affected. From the support-type point of view, alumina-supported NiMo was identified as the most active. SBA-15 support modified the product selectivity to increased formation of the hydrodeoxygenation products in comparison with the ordinary SiO2 support.
