| 摘要 |
A method of decreasing the concentration of nitrogen oxides in flue gases emitted into the atmosphere from combustion systems that burn carbonaceous materials which involves pretreating carbonaceous material particles with vanadium, titanium and ammonia. In the case of coal particles, vanadium, titanium dioxide and ammonium acetate are used to coat the coal particles. The vanadium and titanium dioxide are applied as substantially uniform coatings on the surfaces of the coal particles by incorporating the vanadium and titanium dioxide in emulsions or suspensions.
