Abstract

The study investigated the correlation between the physicochemical properties of certain BEA, MFI, and FAU zeolites and their catalytic activity in conversions of n-heptane, hept-1-ene, and hydrocarbon mixtures with different compositions at 170–260°C. X-ray diffraction, IR spectroscopy, and integrated thermal analysis were utilized for the study purposes. The study identified regularities of hydrocarbon conversions over zeolites within the selected temperature range. In particular, cracking of C₇ hydrocarbons was found to occur through intermediate oligomer formation. It was shown that, under certain conditions, oxygen is recovered from the zeolite lattice to form carbon oxides as reaction products.

在170–260°C时沸石上的烃类催化转化

摘要

这项研究研究了某些BEA，MFI和FAU沸石的理化性质与其在170-260°C下具有不同组成的正庚烷，庚-1-烯和碳氢化合物混合物转化时的催化活性之间的相关性。X射线衍射，IR光谱和集成热分析用于研究目的。该研究确定了在选定温度范围内烃类上烃转化的规律性。特别地，发现通过中间低聚物形成发生C ₇烃的裂化。结果表明，在一定条件下，从沸石晶格中回收了氧，形成了作为反应产物的碳氧化物。
