Abstract
Recently, hydrocarbon refrigerant isobutane (R600a) began to be carried in household refrigerator. The proper processing technology of isobutane is required in order to prepare for recycling of the refrigerator. Isobutane below the inflammable range is oxidized to CO_2 and H_2O by using a palladium catalyst. The catalyst temperature conditions for isobutene completely oxidation were clarified. The temperature distribution of catalyst showed that 60% or more of isobutene had oxidized near the catalyst inlet.
