By selectively hydrogenating a feedstock containing two or more hydrocarbons selected from the group consisting of tricyclic aromatic hydrocarbons having an anthracene skeleton and tricyclic aromatic hydrocarbons having a phenanthrene skeleton to 1,2,3,4,5,6,7,8-octahydro bodies using, as a hydrogenation catalyst, a catalyst containing two or more active metals selected from the group consisting of nickel, molybdenum, cobalt, and tungsten and then, by oxidizing the 1,2,3,4,5,6,7,8-octahydro body using a metal oxide, a benzenetetracarboxylic acid can be efficiently manufactured.
通过选择性加氢含有蒽骨架三环芳烃和苯并芘骨架三环芳烃的混合原料,使用镍、钼、钴、钨等活性金属中的两种或两种以上作为加氢催化剂,将其加氢转化成1,2,3,4,5,6,7,8-八氢体。然后,通过使用金属氧化物将1,2,3,4,5,6,7,8-八氢体氧化,可以高效地制造苯四羧酸。
