采用脉冲微型反应色谱研究了甲醇的分解反应。甲醇在HNaY沸石上的分解活性随着钠离子被交换程度的增加而增加。当交换度小于60%时,甲醇的脱水和脱氢反应同时发生,并以脱水反应为主;当交换度超过80%时,HNaY沸石的脱氢活性消失。在含有碱金属离子的Pd/MY(M=碱金属)沸石上,甲醇的主要分解产物是CO和H_2。与LiY、NaY、KY和CsY沸石相比较,载钯后沸石在脱氢反应中活性明显增高,其活性顺序如下:Pd/CsY>Pd/NaY>Pd/LiY>Pd/KY The reaction of methanol was studied by pulsed microreaction. The decomposition activity of methanol on HNaY zeolite increases with the exchange of sodium ions. When the degree of exchange is less than 60%, the dehydration and dehydrogenation reactions of methanol occur simultaneously, and the dehydration reaction is the main one. When the exchange degree exceeds 80%, the dehydrogenation activity of HNaY zeolite disappears. On Pd / MY (M = alkali metal) zeolites containing alkali metal ions, the major decomposition products of methanol are CO and H 2. Compared with LiY, NaY, KY and CsY zeolites, the activity of zeolites loaded with Pd in ​​dehydrogenation reactions was significantly increased compared to LiY, NaY, KY and CsY zeolites. The order of their activity is as follows: Pd / CsY> Pd / NaY> Pd / LiY> Pd / KY
