In this paper, the physicochemical and catalytic properties of SAPO-11 and SAPO-41 molecular sieves granulated with a binder material and promoted with 0.5 wt % Pt have been studied in the isodewaxing of a hydrotreated diesel fraction. It has been shown that the introduction of ~30 wt % of boehmite, which transforms into alumina under calcination, into the granules leads to a decrease in the micropore volume by 50–70% and an increase in the external specific surface area of the material by 6–12% as compared to the highly dispersed samples of the above molecular sieves. It has been found that, at 340°C, 3 MPa, 2.0 h−1, and H2/feedstock = 800 m3/m3, both samples of bifunctional catalysts provide the production of diesel fuel with a pour point of –42°C and a yield of ~91–92 wt %.
