Pd catalyst

Type HX palladium catalyst is mainly used as deoxygenant for purifying gases such as H2, N2, Ar, With activated alumina as palladium carrier, it is safe and facile to operate and can work efficiently. Technical Parameter: Item Unit Target Appearance Gray-black Sphere Size mm 3-4；3-5 Palladium content(wt) % 0.3-0.5 Bulk density g/ml ≥0.70 Crushing strength N/P ≥59 　　Deoxygenating depth: ● Nitrogen or argon separated from air could be purified to 1 ppm oxygen content after one deoxygenating step. ● The content of oxygen can be reduced to 0.1 ppm possibly. 　　Operation instruction: ● The product is already activated and could be loaded and used directly. ● The space speed should be between 5000 to 10000/hr. ● It’s necessary to add hydrogen into the raw gas according to the oxygen content in gas. ● Whether should the deoxygenant de pre-heated(to 50-80℃) or not depends on the oxygen content in raw gas. ● The working temperature should be lower than 500℃. 　　Packing: Iron drum. 　　Attention: Avoid being disabled by sulfide, chioride or water, otherwise it should be re-activated with heated hydrogen around 200℃ for 4 hours.
