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.

Application
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 which can get very low outlet concentration. Zinc oxide catalyst(ZnO) is widely used in deep desulfurization application for gas phase like syngas, natural gas, off gas, bio gas, coke gas and liquid phase such as polypropylene, naphtha or other light hydrocarbon etc.

The metal oxides or akali within the activated carbon pores can react with the sulfur compounds to form sulfides and sulfates. So the promoted activated carbon can are widely used in sulfur removal which can be regenerated in situ with hot gas containing traces of oxygen to restore the impregnants to the metal oxide form. If large amounts of undesirable high molecular weight organics are present in the feed gas, a guard bed of un-impregnated activated carbon is used.
