    • The present invention relates to a low temperature oxidation catalyst with improved water-stability for removing toxic gas and more specifically, to a low temperature oxidation catalyst for removing toxic gas which is used for the oxidation reaction for directly removing the toxic gas without a preprocessing step at a high temperature by putting water soluble salt of 8B class metal and copper metal used as an active component into a poly(styrene-vinyl benzene) copolymer carrier with moisture. The catalyst of the present invention has extended catalyst lifetime by not generating inactivation even in a condition with the moisture, and also the inactivated catalyst can be recycled after exposing to steam for one or two hours for the large scale processing of the toxic gas.

    • Adsorbent for removing aldehyde compounds is provided to enhance the adsorption force and the performance and persistence in adsorption. A poisonous gas such as acetic aldehyde and ammonia supplied from a gas cylinder(1) is transferred and mixed with oxygen. The diluted mixture gas is passed through the flowing meter controllers(3) and transferred into a fixed layer reactor(5) directly or after passing through the water. The amount and speed of each gas are controlled by the flowing meter controllers. Absorbent is mounted at the intermediate portion of the reactor as a granule type. The mixture gas is passed through an absorbent layer and adsorbed by activation components carried in a carrier and then the adsorbent is measured by a detector.
