OP-II-3

PP-III-31It was concluded that on the investigated catalyst products with high (>60%)paraffin content having boiling points similar to diesel fraction (T = 360-380°C,p = 60-90 bar, LHSV = 1.0-1.5 h –1 , H 2 /sunflower oil volume ratio: 500 Nm 3 /m 3 ) couldbe produced. In case of every investigated process parameter the C 18 -, C 16 -, C 17 -and C 15 - paraffins were formed, i.e. on the applied catalyst both the HDO and thedecarboxylation/decarbonylation (DECARB) reactions took place.References[1].
