Abstract

The isomerization of heptane and hexane and their mixtures in the presence of Pt/WO3–ZrO2 catalysts with a tungsten oxide content of 10–35 wt % has been studied. It has been shown that the best parameters of the isomerization of a mixture of C6–C7 alkanes are achieved in the presence of catalysts containing 15–20 wt % WO3. According to temperature-programmed desorption of ammonia, this range of tungsten oxide content is characterized by an increase in the number of acid sites, which, according to IR spectroscopy of adsorbed CO molecules, occurs mostly due to an increase in the number of Brønsted acid sites.

含铂钨氧化锆催化剂存在下正己烷和庚烷混合物的异构化
研究了在氧化钨含量为10 ~ 35wt %的Pt/ WO3-ZrO2催化剂存在下,庚烷和己烷及其混合物的异构化反应。结果表明,C6-C7烷烃混合物异构化的最佳参数是在WO3含量为15-20 wt %的催化剂中实现的。根据氨的程序升温解吸,该范围内氧化钨含量的特征是酸位的增加,根据吸附CO分子的红外光谱,这主要是由于Brønsted酸位的增加。
