Chistyakov A., Gubanov M., Tsodikov M., 2013, The Direct Conversion of Rapeseed Oil Towards Hydrocarbons over Industrial Catalysts, Chemical Engineering Transactions, 32, 1093-1098.
The current study presents rapeseed oil conversion investigation over industrial Pt/?-Al2O3 and Pd- Zn/MFI/?-Al2O3 catalysts. During reductive pre-treatment of Pt/?-Al2O3 catalyst got new properties that results in the direct hydrogenative treatment of rape seed oil towards alkanes with total yield reached up to 90 wt.% and conversion about 100%. Via temperature varying one may adjust process selectivity towards hydrocarbons either gasoline or diesel fractions. It’s noteworthy that initial oil contained acids with carbon number not exceeds 22, but products composition contained alkanes C23+. The total yield of extra heavy alkanes C23+ was 0.5-5 wt.% depending on process conditions. Obtained data suggested the possibility of intermolecular cross-coupling reaction of glycerol fragments with acid fragments took place.
