测量了焦炭表面氢气和一氧化碳催化还原“NO”的速率，并与焦炭非催化还原“NO”的速率进行了比较。以前报道的焦炭非催化还原“NO”的速率对煤的沸腾床燃烧器中的“NO”排放有显著影响。在氢气和一氧化碳存在下，表面催化还原NO控制了整个NO的破坏。因此，氢和一氧化碳的存在将碳的消耗降低到几乎为零。在沸腾床燃烧室所采用的温度范围内，氢气显著提高了燃烧速率。生成氨与消耗的“NO”的比率随着温度的升高而降低。
The rate of catalytic "NO" reduction by hydrogen and carbon monoxide over a char surface was measured and compared with the rate of noncatalytic "NO" reduction by char which has been previously reported to have a significant effect on "NO" emission control in a fluidized bed combustor of coal. In the presence of hydrogen and carbon monoxide, the surface catalyzed reduction of "NO" controlled the overall "NO" destruction. Thus the presence of hydrogen and carbon monoxide decreased the comsumption of carbon to nearly zero. The rate was significantly enhanced by hydrogen over the temperature range employed for the fluidized bed combustor. The ratio of formed ammonia to consumed "NO" is decreased with an increased temperature.
