摘要: 分别经过低于723K氧化再生,753K空气中焙烧3h,在氢气气氛673K还原2h及723K空气中氧化4h,可使失活NiMo/γ-Al2O3工业加氢脱硫催化剂得到再生,某些再生催化剂样品的加氢脱硫活性甚至超过新鲜催化剂样品.

关键词: NiMo/γ-Al2O3, 加氢脱硫催化剂, 再生, 还原-氧化, 焙烧

Abstract: The hydrodesulfurization(HDS) catalytic activity of spent industrial catalyst NiMo/γ-Al2O3 can be regenerated through oxidation below 723 K, calcination in air at 753 K for 3 h, and reduction at 673 K in H2 for 2 h and oxidation at 723 K in air for 4 h successively. The activity for HDS of some regenerated samples can even be higher than that of the fresh catalyst sample.

Key words: NiMo/γ-Al2O3, hydrodesulfurization catalyst, regeneration, reduction-oxidation, calcination
