Abstract

SAPO-11 molecular sieves with acid site concentrations between 0. 07 and 0. 30 mmol/g were synthesized. The n-heptane hydroconversion over the palladium impregnated catalysts was investigated in the temperature range from 250°C to 350°C at a pressure of 3 bar. The increasing number of strong acid sites was reflected in an enhanced catalytic activity. The selectivity to isomerization was around 95% over the catalysts with high silicon content and decreased with decreasing acid site concentration.
