本文研究了甲醇和苯蒸气在Ａｇ、Ｃｕ、Ｆｅ、Ｃｏ、Ｎｉ、Ｍｎ氧化物催化剂上催化燃 烧的情况，讨论了催化剂活性变化的规律。用有机物转化率大于９９％时的反应温度 ｔｃ的倒数对各种金属氧化物的分解温度ｔｄ作图，在两种情况下都得到“火山型”曲 线． 制备了一种含ＭｎＯ_２的催化剂，在１３０°及空速１３００时－１的条件下可将空气 中的甲醇蒸气完全清除．此催化剂对于清除乙醛、丙酮和其它醇类蒸气也相当有效。 In this paper, the catalytic combustion of methanol and benzene vapor over Ag, Cu, Fe, Co, Ni and Mn oxide catalysts was studied. The variation of catalyst activity was discussed. The decomposition temperature td of the various metal oxides was plotted as the reciprocal of the reaction temperature tc with a conversion of organics greater than 99%, yielding a “volcano” curve in both cases. A MnO 2 -containing catalyst was prepared to completely remove the methanol vapor in the air at 130 ° and airspeed of 1300 h -1. This catalyst is also quite effective at removing acetaldehyde, acetone and other alcohol vapors.
