The heterogeneous NO reduction characteristics with biomass char and coal char blends in a microfluidized bed reaction analyzer (MFBRA) and its kinetic analysis were investigated. Sawdust char had better and longer NO reduction activity compared with those of the other two samples. The order of total reduction ability is sawdust char > rice husk char > coal char. Kinetic analysis of the NO–char reaction showed that coal char had the minimum activation energy, E, and pre-exponential factor, A, while rice husk char had the maximum kinetic parameters. The kinetic parameters of sawdust char were between those of coal char and rice husk char. By comparing the real NO–char reactivity with the calculated kinetic parameters, it can be concluded that the reactivity is represented by both E and A. Moreover, sawdust char/coal char mixing ratios had a linear relationship with E and an exponential relationship with A.

微流化床反应分析仪中生物质炭和煤焦混合物非均相还原NO的研究

研究了微流化床反应分析仪（MFBRA）中生物质炭和煤焦混合物的异质NO还原特性及其动力学分析。与其他两个样品相比，木屑炭具有更好，更长的NO还原活性。总还原能力的顺序是锯末炭>稻壳炭>煤焦。NO–char反应的动力学分析表明，煤焦具有最小的活化能E和前指数因子A，而稻壳焦具有最大的动力学参数。木屑炭的动力学参数介于煤焦和稻壳炭之间。通过将实际的NO-char反应性与计算出的动力学参数进行比较，可以得出结论，反应性由两种形式表示Ë和一个。此外，木屑炭/煤炭混合比与E呈线性关系，与A呈指数关系。
