A999G sulphur tail gas hydrogenation catalyst

A999G sulphur tail gas hydrogenation catalyst at low temperature with TiO2 / Al2O3 as the carrier, such as Co - Mo catalyst hydrogenation process for active components, the catalyst has good activity at low temperature (hydrogenation temperature 220 ~ 240 ℃), large specific surface area, large pore volume, active components distribution uniformity, high hydrogenation activity and organic sulfur hydrolysis activity, good activity stability characteristics. For complex organic sulfides have higher conversion ability. Can be used for sulfur compounds of hydrogen sulfide in tail gas hydrogenation is converted to hydrogen sulfide, emissions in order to achieve environmental protection requirement.
