The experimental results indicated that these metal oxide catalysts had better catalytic activities to the methylene chloride gas at low concentration, and the catalytic activities increased with the increase of temperature,but decreased with the increase of inlet gas concentration. The CrO3/potsherd catalytic activity was better than V2O5/potsherd, and the CrO3/potsherd catalyst displayed higher activity at the relative low temperature. When the reaction temperature was 320 ℃, the conversion rate could reach 99%, and the result of 100h catalyst stability experiment show that the catalytic activities have good stability.

实验结果表明此类金属氧化物催化剂对低浓度CH2Cl2气体有较好的催化活性，催化剂的活性随温度升高而升高，随入口废气浓度增大而降低，其中CrO3/陶瓷片催化剂的催化活性比V2O5/陶瓷片催化剂的活性好，CrO3/陶瓷片催化剂在较低温度下就表现出较高反应活性，在反应温度320℃时，转化率即达到99%，同时催化剂100h稳定性实验结果表明催化剂活性有很好稳定性，为进一步工业化应用提供理论和实践依据。
