AlPO(4)-31 molecular sieve was synthesized by microwave irradiation using aluminum isopropoxide, orthophosphoric acid, and di-n-butylamine as sources of aluminum, phosphorus, and template, respectively. The crystallization conditions of AlPO(4)-31 were optimized. SAPO-31 molecular sieve samples with different silicon contents were synthesized at the optimal conditions. The structure and acidity of the samples were characterized by X-ray diffraction, N(2) physical adsorption, scanning electron microscopy, (29)Si MAS NMR, NH(3) temperature-programmed desorption, FT-IR of adsorbed pyridine. The catalytic performance of Pd/SAPO-31 bifunctional catalyst for hydroisomerization of n-decane was investigated. The results indicated that the AlPO(4)-31 and SAPO-31 molecular sieves with pure crystal phase and higher crystallinity assigned to ATO topology structure were obtained at 170 degrees C for 2 h by microwave irradiation. The BET surface area and micropore volume were increased because of the introduction of Si to the framework of AlPO(4)-31. The distribution of Si in the framework and the acidity of the SAPO-31 molecular sieve were varied by changing the composition of the reaction mixture. The bifunctional catalyst Pd/SAPO-31 with suitable acidity showed high activity and selectivity for hydroisomerization of n-decane.
