Abstract
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.
