本文应用了研究相图与床层温差评价催化活性的方法,研究了在催化深度氧化环己烷或苯的反应中,铜、锰、钴三元氧化物催化剂体系的组成与催化活性的关系.用反应物在催化剂上起燃温度的等温图,描绘出该体系氧化物催化剂对环己烷或苯的催化氧化活性的分布.所得结果指导了用于净化苯系物废气所需催化剂的研制. In this paper, the method of studying the catalytic activity of phase diagram and bed temperature difference was used to evaluate the catalytic activity of Cu, Mn and Co ternary oxide catalysts for catalytic depth oxidation of cyclohexane or benzene. The isothermal plot of the light-off temperature of the reactants on the catalyst is used to characterize the catalytic oxidation activity of the system oxide catalyst for cyclohexane or benzene. The results obtained guide the development of a catalyst for purifying benzene-based exhaust gases.
