- Аннотация: Physicochemical and catalytic properties of molecular sieves SAPO-11 and SAPO-41, which were granulated with a binder and promoted with 0.5 wt.% Pt, were studied in isodeparaffinization of hydrotreated diesel fraction. It was shown that the introduction of ca. 30 wt.% boehmite, which turns into alumina upon calcination, into the granules leads to a 50– 70 % decrease in the micropore volume and a 6–12 % growth of the external specific surface area of the material in comparison with highly dispersed samples of the indicated molecular sieves. Both samples of bifunctional catalysts make it possible to produce diesel fuel with the pour point of –42 °С and the yield of ca. 91–92 wt.% at 340 °С, 3 MPa, 2.0 h–1, and H2 /feedstock = 800 m3/m3.
