摘要: VO x /TiO 2 catalysts were prepared by precipitation-deposition and impregnation method using TiO support obtained sol-gel from titanium isopropoxide. The performance of the was investigated for selective oxidation hydrogen sulfide in stream containing both ammonia excess water. All showed good dispersion vanadium on surface they had high H S conversion without production sulfur dioxide. better catalytic activity compared to those method.
