英文摘要: Four molecular sieves of ALPO-11 and SAPO-5, 11, 34 were synthesized and characterized. The results showed the differences of acidity and porous structure. The four samples were modified by Pd and used in the direct transformation of n-butane to isobutene. Pd/AIPO-11, Pd/SAPO-5 and Pd/SAPO-34 showed low catalytic activity and poor selectivity for isobutene, while Pd/SAPO-11 showed relatively high activity and high isobutene selectivity. The effect of acidity and porous structure on the support Pd and the catalytic performance were discussed. Medium strong acidity and suitable pore geometry were necessary in this reaction.
