Abstract

The physicochemical properties of a series of pelletized SAPO-11 molecular sieves differing in the binder (Al₂O₃) content were characterized; their activity and selectivity were investigated in the hydroisomerization of n-hexadecane. An increase in the binder content from 20 to 60 wt % was found to decrease the specific micropore volume and increase the external specific surface area as well as the mechanical strength, activity, and selectivity of Pt-containing samples in the hydroisomerization of n-hexadecane. The study proposes the formulations of pelletized SAPO-11 that ensure mechanical (axial crushing) strength of 9.9 to 15.1 N/mm² and the yield of C₁₆ isomers up to 78% in the hydroisomerization of n-hexadecane.
