Microporous silicoaluminophosphate molecular sieves SAPO-5 are considered promising acidic catalysts for hydrocarbon conversion processes. However, their catalytic performance is hindered by diffusion limitations, which can be mitigated by reducing crystal size and fine-tuning the acidic properties. The effect of the initial SiO2/Al2O3 ratio in the synthesis gel on the structural and acidic features of SAPO-5 was investigated using XPS, XRD, SEM, N2 adsorption–desorption, NH3-TPD, and IR spectroscopy. An increase in silicon content was found to decrease crystal size and enhance the external surface area. The concentration of Brønsted acid sites reaches a maximum, suggesting limited Si incorporation into the framework. In the hydroisomerization of n-hexadecane, the highest catalytic activity and selectivity towards isoparaffins were observed for the SAPO-5 sample with the smallest crystals and the highest acidity. These findings demonstrate that the structural and acidic properties of SAPO-5 can be effectively controlled through adjustment of the synthesis gel composition.
