As an unconventional organic pollutant, nitrogen-containing organic waste gas is usually highly toxic, and its clean treatment is becoming urgent under the increasingly strict environmental protection require-ments. The nitrogen-containing exhaust gas produced as tar precipitation after cooling down, and it is mostly eliminated by the combustion method to possibly recover heat, but it is easy to produce problems of NOx emission and incomplete combustion. Catalysts for tar oil to convert it as a syngas generally include natural ore materials, transition metals, alkali metals, etc. Synthetic catalysts have controllable physical and chemical properties and are favored because of their high catalytic activity and low price. For the development of an efficient nitrogen-containing organic waste gas to retrieve resources as syngas, the catalyst is a highly important part. The development of catalysts and its process in this aspect is scarce and thus we combed here to provide meaningful guidance for the blossom of catalytic cracking approach.
