dxy-1 type selective catalytic method catalyst main technical parameters:
(adaptation to gas source: acidic analysis gas containing h2s and conversion of h2s in co2)
physical properties
①the physical and chemical properties of the catalyst are strip-like φ5×(5-15).
② specific surface area greater than 100m2/g.
③pore volume greater than or equal to 0.2ml/g.
④the average crushing strength is greater than 80n/pc.
⑤the bulk density is 0.95~1.05kg/l.
⑥abrasion rate is less than 1.0% (m/m).
use process conditions
temperature: 180-280℃
air speed: 1500-2500h-1
pressure: normal pressure-6mpa
main characteristics
wide adaptability of catalyst: it can adapt to the desulfurization of gas with minimum 3000ppm and maximum 100000ppm of hydrogen sulfide.
high purification degree: gas with different sulfur content can be purified up to 30ppm or less, and the lowest can reach 2ppm.
good catalyst selectivity : capable of converting hydrogen sulfide in preference.
catalyst consumption: the catalyst can be used for 3-5 years in one charge, and the amount of one charge is less compared with other catalysts of the same type.
