在非水体系中Fu-9沸石的合成及性质

SYNTHESIS OF Fu-9 IN NON-AQUEOUS SYSTEM AND ITS PROPERTIES

首次在非水体系中合成了Fu-9沸石;利用XRD、GEM,TG-DTA,NH_3-TPD和脉冲微反技术考察其性能。实验结果表明,不同有机物和有机物用量直接影响晶化产物的晶相;非水体系合成的Fu-9沸石表面仍存在两种不同强度的酸中心,并具有较好的二甲苯异构化性能。

Zeolite Fu-9 was synthesized from non-aqueous system for the first time. The properties of Fu-9 were examined with XRD, SEM,TG-DTA, NH_3-TPD and pulsed-microreactor technology. These results show that different organic compounds and organic compound content directly affect the crystalline phase of product.There are also two kinds of acid sites of different strength on Fu-9 formed in non-aquous system. The catalytic properties of Fu-9 are suporior.
