摘要

本文的目的是研究石油的正构烷烃异构化反应是如何在固体纳米催化剂表面发生的。在这个实验中,富芳烃原油的异构化被研究作为辐射暴露的结果。研究发现,产自Alpoid矿床的富钠膨润土-固体酸可作为精炼石油的催化剂。用红外光谱和气相色谱法研究了正构烷烃转化为支链烃的放射性催化反应的可能机理。提出了纳米膨润土的酸性类型对路易斯酸的影响,以解释观察到的结果。纳米膨润土体积所产生的额外辐射能,使富芳石油的辐射分解过程更加有效。同时,研究了支链烃量随剂量变化的动力学特性。本研究的主要目的之一是提高固相吸附束能向体系的转化效率,改善原油中烃类异构化反应。根据固体中受激发电子的行为讨论了碳氢化合物转化的结果。新型的生态友好型纳米催化剂为具有多支结构的碳氢化合物创造了新的机会。

Radiation-induced isomerization reaction mechanism of hydrocarbons on the surface of solid acid
This paper's goal is to investigate how petroleum's n-alkane isomerization reaction occurs on the surface of a solid nanocatalyst. In this experiment, the isomerization of aromatic-rich crude oil is being studied as a result of radiation exposure. It was discovered that sodium-rich bentonite –solid acid, from the Alpoid deposit works well as a catalyst for refining petroleum. Possible mechanisms of the radio-catalytic reaction that converts n-alkanes to branched hydrocarbons have been researched by methods of FT- IR spectroscopy and gas chromatography. The effect of acidity type of the nanostructured bentonite clay on Lewis acid cites is proposed to explain observed results. Additional radiation energy, which is mainly generated due to the nanobentonite volume, results in a more efficient aromatic- rich petroleum radiolysis process. Also, it was investigated the dynamics of dose –dependent changes in the amount of branched hydrocarbons. One of the primary objectives of this research work is increasing the efficiency of transformation of adsorbed beam energy in solid phase to the system and improvement of hydrocarbon isomerization reactions in crude oil. The results of hydrocarbon transformations are discussed in terms of the behavior of excited electrons in solids. Novel eco-friendly nanocatalyst creates new opportunities for hydrocarbons with multi- branched structures.
