Several chemical methods have been employed for hydrogen sulfide removal such as phosphate, iron oxide, the hydroxide method, activated carbon adsorption, molecular sieve and the zinc oxide (ZnO) method. Among them ZnO catalyst method proved to be the most effective for sulfur compounds removal and H2S in particular. From the standpoint of high H2S removal efficiency, zinc oxide is more attractive than iron oxide because of more favorable sulfidation thermodynamics. Zinc oxide catalyst is used as a mixture of ZnO as a binder in addition to some fillers or binder materials.
