摘要：
A catalyst for low-temperature decomposition of dmitrogen oxide in tail gases from a nitric acid plant based on cobalt oxide comprises, calculated as simple oxides: cobalt oxide at the level of 45.00-99.97 weight %, nickel oxide at the level of 0.01-30.00 weight %, zinc oxide at the level of 0.01-20.00 weight % as principal structural components and activity promoters in the form of alkali metals, such as Na and/or K, at the level of 0.01-5.00 weight % and shape-facilitating alkaline earth metal oxides, such as Ca and/or Mg, at the level of 0.01-5.00 weight %. The invention provides also a process for the preparation of a catalyst.
