Research of performance of hydrogenation catalyst about DMT

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.
