Реферат:
Ni-phosphide catalyst on composite Al2O3-SAPO-11 support was studied in the hydrodeoxygenation-isomerization (hydroconversion) of methyl esters with different amount of carbon atoms in the chain and different number of double bounds: C16 ∶0-methyl palmitate, C18 ∶0-methyl stearate, C18 ∶1-methyl oleate, C18 ∶ 2-methyl linoleate, and C18 ∶ 3-methyl linolenate. The catalyst was synthesized by impregnation of the support with aqueous solution of Ni hypophosphite with subsequent reduction in H2 flow. The catalyst was characterized by ICP-AES analysis, N2 physisorption, H2-TPR, NH3-TPD, XRD, and 27Al MAS NMR. The hydroconversion experiments were carried out in a flow reactor at 310-340 ℃, 2. 0 MPa, 5. 3 h-1. 100% conversion of all esters was achieved. The number of carbon atoms was shown to influence the selectivity to iso-alkanes (at 340 ℃ for C16 ester it was ~ 22%, and for C18 esters it was ~ 30%), but the number of double bonds did not show any impact on the selectivity of iso-alkanes.
