Abstract
In this study, the preparation conditions for a TiO2-based vanadium-based catalyst for oxidizing hydrogen sulfide at room temperature were optimized. Four types of commercial TiO2 were used as a catalyst support and the performance evaluation of hydrogen sulfide oxidation at room temperature of V/TiO2 by varying vanadium contents prepared using the impregnation method was performed. Among the types of TiO2 tested, it was confirmed that the catalyst with the vanadium content of 5% and based on TiO2(A) has the best hydrogen sulfide conversion rate of 58%. By comparing the physical and chemical properties of the catalyst, the specific surface area of the support and the species of dominant vanadium are the major factor in catalyst performance. In order to confirm the regeneration characteristics of the catalyst with reduced activity, heat treatment was performed at 400 ℃ for 2 h, and the amount of hydrogen sulfide oxidation decreased by 10% due to the partial deposition of sulfur in the regenerated catalyst, but it was confirmed that the initial performance was similar.
