失活NiMo/γ-Al2O3工业加氢催化剂的再生
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/V-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.

Regeneration of Spent Industrial NiMo/γ-Al2O3 Catalysts for HDS
Abstract:
The hydrodesulfurization(HDS) catalytic activity of spent industrial catalyst Ni-Mo/V-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.
