摘　　要：新型对苯二甲酸加氢精制催化剂——CTP-Ⅴ型钯炭催化剂在首次工业应用试验中稳定运行一段时间后突然失活,通过对卸出的催化剂及装置中相关原料与辅料的分析研究,确定精制单元排气洗涤塔回收水中存在的多种异物及杂质进入反应系统,尤其是碱洗钯炭催化剂时碱液中的硫化物进入系统,是导致新型催化剂最终失活的主要原因,并提出了针对性的优化措施。In view that the new type catalyst for hydrofining of terephthalic acid- CTP- V type Pd / C catalyst was deactivated accidently after a period of stable operation in the first industrial application test,the main causes were found to be inflowing of various impurities to the system from the recycled water of vent scrubber,especially the sulphides in alkali liquid for cleaning Pd / C catalyst. Pointed countermeasures were raised for optimization.
