在常压固定床微反装置上研究了顺酐加氢催化剂ＸＹＦ－５还原条件对反应结果的影响。结果表明，还原温度是影响催化剂活性的决定性因素，用氮气稀释氢浓度有利于还原温度的稳定，适当提高还原温度可以缩短还原时间
The effect of the reduction conditions of maleic anhydride hydrogenation catalyst XYF-5 on the reaction results was studied on an atmospheric fixed-bed micro-reactor. The results showed that the reduction temperature was the decisive factor affecting the catalyst activity. The dilution of hydrogen concentration with nitrogen was favorable to the stability of the reduction temperature. Appropriately increasing the reduction temperature could shorten the reduction time
