管状钯膜反应器中的脱氢反应与氢气分离

讨论了钯膜反应器的实验装置及环己烷的脱氢反应实验方法。对环己烷的脱氢反应及氢气通过钯膜的渗透建立了扩散模型，使用状态－变量法求解偏微分方程组，得出反应物和生成物的组分浓度分布，进而求出反应转化率。同实验结果对比表明，扩散模型能较好地计算脱氢反应及氢气的分离过程。

オaotsugu　Itoh(National　Institute　of　Materials　and　Chemical　Research,Japan)The　experimental　apparatus　of　palladium　membrane　reactors　and　the　dehydrogenation　of　cyclohexane　are　discussed　herein.A　diffusion　model　is　proposed　to　the　processes　of　the　dehydrogenation　and　separation　of　hydrogen　through　the　palladium　membrane.　The　distributions　of　the　concentrations　of　all　the　reactants　and　products,and　then　the　reaction　rate,are　obtained　by　solving　the　partial　differential　equations　with　the　numerical　State Variable　Algorithm.　Compared　with　the　results　of　experiments,it　is　found　that　the　diffusion　model　can　successfully　simulate　the　processes　in　the　reactor.
