The correlation between the physico-chemical properties of Nb-doped nickel supported on ordered mesoporous alumina catalysts and product distribution during hydrogenolysis of glycerol with in situ produced hydrogen in continuous was investigated. The synthesis of alumina was carried out by the evaporation induced self-assembly (EISA) method. To achieve different interaction strengths among Ni, Nb and Al, the catalysts were prepared by co-impregnation of Ni and Nb on alumina, successive impregnation on alumina, and Ni impregnation on Nb-modified alumina using a Ni/Nb atom ratio of 2. Catalytic runs were performed at 235 ºC/ 45 bar for 30 h TOS, at 12.2 h WHSV.

有序介孔氧化铝负载 Nb 掺杂 Ni 催化剂上无外部 H2 的甘油氢解

研究了有序介孔氧化铝负载铌掺杂镍催化剂的物理化学性质与原位连续制氢甘油氢解过程中产物分布之间的相关性。氧化铝的合成是通过蒸发诱导自组装（EISA）方法进行的。为了实现Ni、Nb和Al之间不同的相互作用强度，催化剂通过Ni和Nb在氧化铝上的共浸渍、在氧化铝上的连续浸渍以及Ni在Nb改性氧化铝上的浸渍（Ni/Nb原子比为2）来制备。催化运行在 235 ℃/45 bar 下进行 30 小时 TOS，12.2 小时 WHSV。
