Product Name: Zinc Oxide Desulfurizer for Hydrogen Sulfide Removal with ASTM Standard, Ds2 Series Model NO.: Biogas desulfurizer, DS2 series, ASTM standard Color: White Usage: Zinc Oxide Desulfurizer Appearance: White Formula: ZnO CAS No.: 1314-13-2 Zin Oxide Desulfurizer: 95% Trademark: Lerona Transport Package: 25 Kgs Woven Bag, Plastic Bucket Origin: China Product Description Zinc oxide desulfurizer for hydrogen sulfide removal with ASTM standard, DS2 seriesZinc oxide desulfurizer, Biogas desulfurizer, H2S removal, DS2 seriesUsage and FeaturesThe feed gas can be natural gas, petroleum gas, light oil gas, synthetic gas, coal gas, semi-water gas and other various gases. Usage of type DS2 zinc oxide desulfurizer at a low temperature can guarantee high purity of gases containing large amount of inorganic sulfur(1-2 g/m3) and small simple organic sulfur(such as COS,CS2). It's suitable to remove hydrogen sulfide both at high(350-450C and low temperatures(30-350C), while it's better for high temperature.Zinc oxide desulfurizer can also be used as a protective agent for synthesizing carbinol, hypoallergenic and methanation catalyst.The usage:Serve as raw material of fine desulfurization when using natural gas or light oil vapor gas conversion makes hydrogen or ammoniaServe as conversion catalyst to protect methane before conversion catalyst when coke-oven gas makes ammoniaServe as low transformation protectant before copper low temperature conversion catalyst when using natural gas or naphtha as raw material makes ammonia or hydrogenOther techniques for fine desulfurization Features of chemical equationZnO+H2S=ZnS+H2OCS2+4H2=2H2S+CH4COS+H2=H2S+COCOS+ZnO=ZnS+CO2Package:25 kgs woven bag, or plastic bucketProposed Application Direction:Temperature: 30~450C, renewable materialPressure: normal pressure to 0.1-4.0 MpaH2S content of air inflow:3000 ppm H2S content of air outflow:20 ppmHumidity: relative humidity 20~100%, water content in bed is strictly prohibitedBed layer height and tower diameter ratio: ≥2Physical properties TypeDS2-ADS2-BDS2-CAppearanceWhite cylindrical particlesGray cylindrical particlesGray cylindrical particlesSize, mmDiam:4-5mm, Length:5-15 mmDiam:4-5mm, Length:5-15 mmDiam:4-5mm, Length:5-15 mmBulk density,kg/l0.85-0.950.9-1.10.9-1.1Strength,N/cm35 min30 min30 minBET,m 2 /g60 min100 min100 minZnO,%80 min85 min85 min.Using conditionTypeDS2-ADS2-BDS2-CTemperatureRoom temper-200CRoom temper-450C430-800CPressure, Mpa5.05.05.0Airspeed500-1000/h500-1000/h500-1000/hSulfur species in materialH2SH2SCOSCS2H2SCOSCS2Total sulfur in material ,ppm≤10≤10≤10Sulfur capacity, %10-1515-2515-25Desulfurization precision,ppm≤0.05≤0.03≤0.03
