Реферат:
A series of bifunctional 1%Pt/SAPO-31 catalysts were prepared by the impregnation of SAPO material with H2PtCl6 solution followed by calcination at temperatures ranging from 250 to 650 °C. Their performance in the one-stage sunflower oil transformation was studied. The high iso-alkanes yield was obtained only over samples calcined at 450–550 °C. The decrease in calcination temperature as well as its increase results in a significantly lower iso-alkanes amount in the final product. The properties of the metal component in 1%Pt/SAPO-31 catalysts was characterized by XPS, TPR, SEM, TEM, H2 chemisorption and studied in benzene hydrogenation. The acidic properties were evaluated by FTIR of adsorbed pyridine and tested in the hydroconversion of n-decane and 2,2,4-trimethylpentane (TMP). Despite the same chemical composition of 1%Pt/SAPO-31 catalysts, the variation of calcination temperature leads to observable change in Pt dispersion and surface acidity of SAPO material.
