将少量硫化合物与氮化合物分别加入环己烷或正庚烷中,在铂重整条件下进行反应,发现硫化合物与氮化合物具有明显不同的中毒作用.硫化合物阻抑脱氢、加速异构化反应,氮化合物阻抑异构化而加速脱氢.这个结果说明脱氢与异构化反应是受催化剂表面的复合活性中心(活性集团)中不同原子的作用而进行的。考察了五种不同的硫化合物与两种不同的氮化合物对环己烷脱氢及正庚烷异构化的影响.也考察了反应条件对于硫化合物对环己烷脱氢以及氮化合物对正庚烷异构化的中毒影响.
A small amount of sulfur compounds and nitrogen compounds were added to cyclohexane or n-heptane, respectively, and the reaction was carried out under the condition of platinum reforming, and it was found that sulfur compounds and nitrogen compounds had significantly different poisoning effects.Sulfur compounds inhibited dehydrogenation and accelerated isomerization The dehydrogenation and isomerization reactions are accelerated by the isomerization of the nitrogen compounds and are inhibited by the isomerization of the nitrogen compounds. This result indicates that the dehydrogenation and isomerization reactions are carried out by the action of different atoms in the complex active center (active group) on the catalyst surface. The effects of five different sulfur compounds and two different nitrogen compounds on the dehydrogenation of cyclohexane and the isomerization of n-heptane were also investigated. The effects of reaction conditions on the dehydrogenation of cyclohexane to cyclohexane and the alignment of nitrogen compounds Toxic effects of heptane isomerization.
