Synthesis of High Si-containing SAPO-11 by Post-Si Method

High Si-containing SAPO-11 molecular sieve with enhanced SAPO domain has been successfully synthesized with diethylamine template by modified hydrothermal method. The sample was characterized with XRD, EDX, N2 adsorption, SEM, 29Si MAS NMR, NH3-TPD. Bifunctional hydroconversion of n-dodecane on Pd/S...

Description
Summary:High Si-containing SAPO-11 molecular sieve with enhanced SAPO domain has been successfully synthesized with diethylamine template by modified hydrothermal method. The sample was characterized with XRD, EDX, N2 adsorption, SEM, 29Si MAS NMR, NH3-TPD. Bifunctional hydroconversion of n-dodecane on Pd/SAPO-11 catalyst showed high hydroisomer conversion and selectivity compared with the results of catalyst prepared by the normal method. The enhanced SAPO domain improves the catalytic results.
