Effects of pore structure on anti-sulfur poisoning of the catalyst for high concentration carbonyl sulfide hydrolysis
Abstract:A series of COS hydrolysis catalyst were prepared by using polymer or cellulose or inorganic salts,or any mixtures of these three kinds of material as pore-forming agent.The pore structure of catalysts were characterized by mercury porosity method and correlated with the conversion and sulfur deposit of catalyst.The results show that the catalyst using the mixtures of all these three kind of material as pore-forming agent has the maximal pore volume and surface area as well as the optimum tortuosity channel,in favor of the diffusing of H2S in catalyst,and hence exhibit the super ability of anti-sulfur poisoning.
