The natural gas can be considered as the main raw material for fertilizer and petrochemical industries, in addition of being the main source of gas fuel. Hydrogen sulfide is poison material with unpleasant odor and corrosive in addition of being poison for most industrial catalysts. Unfortunately, hydrogen sulfide is present in an appropriate amount in natural gas that affect the efficiency of catalysts used in fertilizer production. Accordingly it must be removed it from the feedstock. Several chemical methods have been employed for hydrogen sulfide removal such as phosphate method, iron oxide method, the hydroxide method, activated carbon adsorption method, promoted molecular sieve method and the zinc oxide method.
AOKTEC offer ZnO catalyst, Ferric oxide desulfurizer, MnO based sulfur removal adsorbent, CuO based sulfur removal catalyst, Promoted activated carbon, Promoted zeolite for desulfurization of gas & liquid phase feed which can work under wide ranges of working temperature,
