Abstract

PURPOSE:To ensure a conversion of NO<->3 collected through the selective adsorption into an activated material with a contact reduction, by changing the adsorbent of the nitric acid ion in the solution into a specified inorganic compound carrier which carries the specified metal. CONSTITUTION:One or more kinds of the metal ions of the palladium, platinum, copper and iron are carried on the porous inorganic compound carrier composed of the alumina or titania. And then the metal is deposited onto the carrier through the heat reduction to obtain the absorbent. About >=0.5wt% of the whole absorbent is sufficient for the metal quantity to be carried. A proper amount of this absorbent is added into the solution and then standing it for about 1 or 2 hours at a room temperature -50 deg.C to carry out the adsorption. Then the hydrogen gas is allowed to pass into the solution of about 1l/min to carry out the reduction. As a result, the adsorbed NO<->3 can be converted into more activated material such as NH<+>4 or the like.
