摘要
通过浸渍法制备β-Al2O3负载重金属催化剂,并考察了其对于DMT一段加氢生成DMCD的催化性能.研究发现:当活性β-Al2O3负载重金属Pd或Ru时,加氢反应的转化率和选择性效果理想.并且对加氢催化剂进行了表征,确定了影响催化剂活性的因素.
The supported heavy metal β-Al2O3 catalysts were prepared through dip coating method, and all the different catalysts were evaluated on their catalytic properties for the first stage hydrogenation of DMT to DMCD. It is found that Pd or Ru shows the excellent catalytic activity both at conversion and selectivity. The prepared samples were characterized by the nitrogen adsorption-desorption experiment, the main factors which affected catalyst activity were determined.
