Product Description

1. Features and Scope of Application Zinc Oxide Desulfurization Adsorbent T**5 is widely applicable to feedstock purification processes in production of hydrogen, ammonia, alcohols and organic chemicals. It can remove hydrogen sulfide from various feed gases (oils) to as low as less than 0.1ppm. Main reaction of the desulfurization process is as follows: H2S+ZnS=ZnS+H2O The adsorbent also is capable of converting and absorbing simple organic sulfur such as COS and CS2. Adsorbent T**5 is highly adaptable. It can work in severe conditions with high sulfur absorption capacity, high activity, high strength , good sustainability for activity and sulfur absorption capacity, and good tolerance to high steam to gas ratio. It can obtain satisfactory operation results both at higher ( about **0) and lower (about **0) temperature. ***** and Physical Properties Appearance : white or light-gray extrusions Particle size , mm : Φ4mm�***0mm Bulk density, kg/l : 1.**1.3 loss On Ignition, % : max2 Zinc oxide content, % : min*5 3.Quality Standard loss on abrasion : max6 Breakthrough sulfur capacity : min****0 min****0 ***** Operation Condition Feedstock: light oil , residue cracking gas, natural gas, synthesis gas, coal gas and shifted gas, with recommended hydrogen sulfide concentration of less than **0 ppm.
