摘要：在开发甲醇氧化羰化ＣｕＣｌ２／Ｃ催化剂的基础上，研究了该催化剂的失活与再生。采用ＸＲＤ、ＡＥＳ及孔结构测试等手段，对催化剂的结构变化情况进行表征，发现催化剂失活的原因是活性组分中氯流失所致。为此，选择了一种有机化合物再生催化剂，经过数次再生，催化剂可保持原有活性。
Based on the development of the direct oxidationand carbonylation of vapor phase methanol for DMC production, the deactivation and regeneration of the catalyst has been studied. Methods of surface analysis such as XRD, AES and pore structure analysis, were used to characterize the catalyst. Deactivation of the catalyst was attributed to the loss of chlorine, the result is comparied with simulated experiments. An organic substance is elaborately selected to regenerate the deactivated catalyst. After several times of regeneration, the activity remains unchanged
