We determined that with the application of LCO in the feedstocks the density of the products can be increased. With the formed n- and isoparaffins (from the WCO content of the feedstocks) the higher aromatic content (lower cetane index) of the products—caused by the unconverted LCO components—could be partly compensated and the second generation biocomponent content can be assured. On the pre-sulphided catalyst the best products could be produced in case of T=360°C, P=30bar, LHSV=1.0h−1, H2/feedstock ratio=420Nm3/m3 process parameters and 10-15% WCO content of feedstocks. The polyaromatic content of the main products was under 8w/w% applying the advantageous process parameters, even though the LCO content of the feedstocks. The cetane indexes of the main products changed between 48 and 50, their sulphur content was under 10mg/kg until blending 10% of WCO, in case of 15% WCO content was still just 13mg/kg. We concluded, that increasing the triglyceride content of feedstocks above 15% is not recommended, because of the increased oxygen content the sulphur removal reactions are forced back. The cause of this is that the sulphur- and oxygen removal reactions are occuring on the same active sites of the catalyst, as well as the aromatic hydrogenation reactions, which are contributing to achieve the high degree of desulphurization.
