Abstract
The authors study the effect of the type of zeolite (SAPO-11, ZSM-22, ZSM-23, and ZSM-12) in a support (ratio zeolite : Al2О3 = 30 : 70) on the physicochemical properties of Pt/Al2O3-zeolite catalysts and the composition of products from the hydrodeoxygenation of sunflower oil on them. The possibility of the complete hydrodeoxygenation of sunflower oil at temperatures of 320–350°C, a pressure of 4 MPa, and a weight hourly space velocity (WHSV) of 1 h−1 is shown with 75–82% yields of liquid products. The fraction of iso-alkanes and the yield of direct hydrodeoxygenation products grow along with the concentration of Brønsted acid sites in a catalyst in the order 1%Pt/Al2O3-ZSM-22 < 1%Pt/Al2O3-ZSM-12 < 1%Pt/Al2O3-ZSM-23 < 1%Pt/Al2O3-SAPO-11.
