Abstract:
Silicoaluminophosphates SAPO-31 varying in silica content were prepared by hydrothermal treatment of initial reaction mixture using di-n-pentylamine as a template. The obtained samples were examined by IRS of adsorbed CO molecules. It is found that concentration of strong acid sites increases along with the growth of Si content even at high Si/Al ratios. Catalytic properties of Pt-SAPO-31 were studied in hydroisomerization of n-octane in a temperature range 300–350°C. There is a direct dependence of the samples activity on their chemical composition and acidic properties. Selectivity to isomerized and cracked reaction products is influenced by both reaction conditions and Si content in the catalysts.
