通过分析焦炭N 与O 2、CO 2的反应，研究焦炭N 转化为含N 产物的化学过程和析出特性。实验在固定床反应器上进行，压力为0.1～1.0M Pa。结果表明：O2、CO2和N2等主要检测产物与反应气体有关。在较宽的压力和CO2体积分数范围内，焦炭N 与CO2反应生成N2的反应具有很高的选择性。以O2和CO2为反应气体时，反应压力对气化产物的分布影响较小。当O2作为气化剂时，NO 和HCN 是主要产物，而且其他检测产物会由这些主要产物在焦炭表面相互反应得到。

The chem istry of char-N release and conversion to nitrogen-containing products has been probed by studying its release and reactions w ith O 2 and CO2.T he experim ents w ere perform ed in a fixed bed flow reactor atpressures of up to 1.0 M Pa.T he results show thatthe m ajor nitrogen-containing products observed depend on the reactantgas;w ith O 2,N O ,and N 2 being the m ajor species observed. C har-N reaction w ith CO2 produces N 2 w ith very high selectivity over a broad range of pressures and CO2 concentrations.O bserved distributions of nitrogen-containing products are little affected by pressure w hen O 2 and CO2 are the reactantgases.T he results suggestthatN O and H C N are prim ary products w hen O 2 is used as the reactant gas,and thatthe otherobserved products arise from interactions ofthese prim ary products w ith the charsurface.
