¡ñ Na model crystal structure £¬ it is a kind of effective deoxidation-catalyst and it has an alias of A-model-molecular-sieve ¡£It is mainly applied to adsorb oxide in the production of H2 (which is produced by electrolyzing water) and mixed gas of nitrogen and hydrogen in normal temperature ¡£ Its high catalysis ability ¡¢low price and practicality is its main advantage.
¡ñ Size £º§æ3-5mm¡¢ §æ4-6mm£¬crystal structure ¡£
¡ñ Particulate size £º ¡Ý 98 %¡£
¡ñ Heap density £º¡Ý 0.68 g /ml ¡£
¡ñ Crush strength £º¡Ý 80 N/bead ¡£
¡ñ Wear rate £º¡Ü 0.3 %¡£
¡ñ Deoxidize-activity £ºthe remaining Oxygen will be less than 1PPM work is normal and the air speed is less than 3000-5000 H-1¡£
¡ñ It has not be deoxidized before leave factory,so it needs to deoxidize the filling container with stuff hydrogen or mixing gas of hydrogen and nitrogen ¡£
¡ñ The temperature should be controlled between 350 and 400 ¡æ ,the airspeed should be in the range of 200 and 300 H-1£¬after keeping 3 hours ,cool it to normal temperature for later use.
¡ñ in normal temperature ,once the deoxidization effect decrease ,we can regenerate it with the stuff hydrogen ,keep the temperature between 200 and 250 ¡æ ,and the airspeed between 200 to 300 H-1£¬and such state should be kept for 3 to 4 hours ¡£ Its activity does not change after regeneration.
¡ñ If the using temperature is between 100 and 102 ¡æ ,it can still work properly.
¡ñ Before the stuff gas is deoxidized ,molecular-sieve must be used ,the purpose of which is to keep its deoxidize activity ¡£
¡ñ 20Kg ¡¢25Kg paper box or steel bucket sealed, 2Kg vacuum aluminum foil bag ¡£
¡ñ Please do not expose it in the air in order to avoid adsorption of moisture ¡£
¡ñ It is not encouraged to catalyze stuff gas with chloride and sulfide in which,to avoid invalidation with toxicosis ¡£
