Abstract
The effect of the zeolite type (SAPO-11, ZSM-22, ZSM-23 and ZSM-12) in the support (the zeolite to Al2О3 ratio of 30 : 70) on physicochemical properties of Pt/Al2О3-zeolite catalysts as well as on the yield and composition of the products of sunflower oil hydrodeoxygenation over these catalysts was studied. The possibility of complete hydrodeoxygenation of sunflower oil at temperatures 320–350 °C, pressure 4 MPa, and mass flow rate 1 h–1 with the yield of liquid products 75–82 % was demonstrated. The fraction of isoalkanes and the yield of products from direct hydrodeoxygenation increase with the concentration of Broensted acid sites in the catalyst in the following series: 1%Pt/Al2O3-ZSM-22 < < 1%Pt/Al2O3-ZSM-12 < 1%Pt/Al2O3-ZSM-23 < 1%Pt/Al2O3-SAPO-11.
