Review of Hydrogen Sulfide Removal from Various Industrial Gases by Zeolites

Hydrogen sulfide (H2S) removal from various industrial gases is crucial because it can cause huge damage to humans, the environment, and production. Zeolite possesses specific surface area well-developed pore structure, making a promising adsorbent for H2S removal. This review attempts comprehensively compile current studies in literature on gas purification processes using zeolites, including experimental simulation studies, mechanism theory, practical applications. Si/Al ratio, cations of zeolite, composition operating conditions, diffusion zeolites affect desulfurization performance. However, further efforts are still needed figure out influence rules factors above mechanisms. Based an extensive compilation literature, we attempt shed light new perspectives research future.
