摘要

文章展示了通过用锌盐水溶液浸渍然后热分解的方法合成沉积在颗粒状（upgamma -{text{AI}}_{2}{text{O}}_{3}/）基底上的氧化锌基硫化学吸附剂的可能性。通过低温氮吸附、X 射线衍射和扫描电子显微镜研究了所得吸附剂的强度和纹理特性。与天然气处理中使用的传统氧化锌吸附剂相比，合成的吸附剂具有更高的强度和更有效的表面利用率。与工业用锌基吸附剂相比，所提出的吸附剂具有相对较高的（{text{H}}_{2}\text{S}）静态硫吸附容量。

Granular Chemisorbent Based on Zinc Oxide Supported on γ – AI2O3

The article shows the possibility of synthesizing a ZnO-based sulfur chemisorbent deposited on a granular \(\upgamma -{\text{AI}}_{2}{\text{O}}_{3}\) substrate by impregnating it with an aqueous zinc salt solution followed by thermal decomposition. The strength and textural properties of the obtained sorbent were studied via low-temperature nitrogen adsorption, x-ray diffraction, and scanning electron microscopy. The synthesized adsorbent exhibits higher strength and more efficient use of the surface than conventional ZnO-based sorbents used in natural gas processing. The proposed sorbent showed relatively high static sulfur capacity for \({\text{H}}_{2}\text{S}\) adsorption as compared to industrial zinc-based counterparts.
