AI Technical Summary
Under high ammonia-to-diesel ratio conditions, existing technologies are ineffective in treating unburned ammonia and nitrogen oxides, and traditional devices cannot effectively remove high concentrations of ammonia and N2O.
A renewable ammonia adsorbent and a low-temperature ammonia decomposition catalyst are used to partially decompose high-concentration ammonia. Combined with an SCR catalyst and a low-temperature ammonia oxidation catalyst, unburned ammonia and nitrogen oxides are removed through a series reaction, avoiding the use of additional reducing agents.
It effectively reduces the concentration of unburned ammonia, removes nitrogen oxides and carbon monoxide to meet emission standards, has a simple structure, and provides good purification effect.
