摘要

在280 ~ 390℃的温度范围内,在不同的甲基环己烷:氧:氮比、气体混合物空速1000 ~ 3000 h-1和常压条件下,研究了不同过渡元素阳离子和非过渡元素阳离子改性的合成沸石和天然沸石在甲基环己烷氧化脱氢制甲基环己二烯1,3的气相反应中的催化性能。研究发现,天然斜沸石与阳离子Co2+结合;量为0,5的Cr3+;分别为0.25% wt.,是甲基环己烷氧化脱氢生成甲基环己二烯-1,3的活性催化剂。

OXIDATIVE DEHYDROGENATION OF METHYLCYCLOHEXANE OVER MODIFIED ZEOLITES
In the temperature range 280-390°C, at different ratios of methylcyclohexane:oxygen:nitrogen, space velocity of the gas mixture 1000-3000 h-1 and at atmospheric pressure it has been investigated the catalytic properties of synthetic and natural zeolites modified with various cations of transition and non-transition elements in the vapor-phase reaction of oxidative dehydrogenation of methylcyclohexane to methylcyclohexadiene-1,3. It has been found that the natural clinoptilolite with a combination of cations Co2+; Cr3+ in amounts of 0,5; and 0,25% wt., respectively, is an active catalyst for the oxidative dehydrogenation of methylcyclohexane to metylcyclohexadiene-1,3.
