Abstract
The paper comparatively assesses the physicochemical properties of natural aluminosilicate nanotubes (halloysite) provided by domestic (HNT-Ch) vs. foreign (HNT-A) manufacturers, as well as the catalytic activity of ruthenium catalysts synthesized therefrom. The composition, structure, and textural properties of the materials were measured by a combination of physicochemical methods, such as TEM, ED–XRF, low-temperature nitrogen adsorption/desorption, and H2–TPR. The activity of the synthetic catalysts was examined in benzene hydrogenation at 80°C and a hydrogen pressure of 3 MPa in both a hydrocarbon and aqueous–hydrocarbon system. The catalysts supported on HNT-Ch and HNT-A were found to have similar physicochemical properties and to exhibit high activity in benzene hydrogenation, both in the monophasic and biphasic systems, thus ensuring quantitative substrate conversion with 100% cyclohexane selectivity.

基于不同来源埃洛石硅铝酸盐纳米管的含钌催化剂苯加氢
摘要
论文比较了国内（HNT-Ch）与国外（HNT-A）厂家提供的天然铝硅酸盐纳米管（埃洛石）的理化性质，以及由此合成的钌催化剂的催化活性。材料的组成、结构和质地特性通过物理化学方法的组合测量，例如 TEM、ED-XRF、低温氮气吸附/解吸和 H 2-TPR。在 80°C 和 3 MPa 的氢气压力下，在碳氢化合物和水-碳氢化合物体系中，在苯加氢反应中检测了合成催化剂的活性。发现负载在 HNT-Ch 和 HNT-A 上的催化剂具有相似的物理化学性质，并在苯加氢中表现出高活性，无论是在单相系统还是双相系统中，从而确保以 100% 环己烷选择性进行定量底物转化。
