Abstract
Notice of Retraction
After careful and considered review of the content of this paper by a duly constituted expert committee, this paper has been found to be in violation of IEEE´s Publication Principles.
We hereby retract the content of this paper. Reasonable effort should be made to remove all past references to this paper.
The presenting author of this paper has the option to appeal this decision by contacting TPII@ieee.org.
The catalyst for carbonyl sulfide hydrolysis at moderate temperature was prepared by using γ-Al2O3 as a carrier and TiO2 as the modifying agent. The atmospheric effects for carbonyl sulfur hydrolysis at moderate temperature were carried out in simulated coal gas using a fixed-bed reactor. And the crystal phases of both fresh catalysts and used catalyst were characterized by using X-ray diffraction. The experimental results show that COS stable conversion was about 80% in simulated coal gas and less than that in N2 atmosphere. CO, CO2 and H2 in stimulated coal gas may decrease COS conversion due to these gases adsorption on surface activity site of catalyst. The conversion of COS has a maximum value with the change of the ratios of water vapor to COS concentration. Hydrolysis of COS is one-order reaction for COS concentration. There was no hydrogenlysis in H2-containing atmosphere for COS hydrolysis catalyst, and there was no poisoning for COS hydrolysis catalyst in simulated coal gas atmosphere.
