摘 要: Cr—Co—O/D3520催化剂在催化氧化四氢萘中,其性能显著优于单组分Co或Cr催化剂。多种物理测试研究表明,金属间存在相互作用,增加了吸附O2-量,解释了其高活性原因。研究还表明,活性组分与我体D3520(吸附树脂)间存在弱相互作用,对金属组分的高分散性及较长的使用寿命给予了解释。 The activity of the Cr-Co-O/D3520 catalyst is obviously better than that of the Co3O4 / D3520 or Cr2O3 / D3520 catalyst in the oxidation of Tetralin. The various physical tests show that the intermetallic interaction results in the increase of adsorption of O2-,which is the cause of high activity of Cr-Co-O/D3520.The tests also indicate the high dispersivity of metallic composition and long life of catalyst, thus suggest the presence of the weak interaction between metal and D3520(adsorption resin).
