Effects of heating rate and AAEM on the production of NH3 and HCN during pyrolysis of shengli brown coal
This study is to examine the effects of heating rate and AAEM (alkali and alkaline earth metallic species) on the generation of NH 3 and HCN during the pyrolysis of Shengli brown coals at two different temperatures of 773 and 1073 K. All the experiments were conducted in a fixed-bed/fluidised-bed q...

| description | This study is to examine the effects of heating rate and AAEM (alkali and alkaline earth metallic species) on the generation of NH 3 and HCN during the pyrolysis of Shengli brown coals at two different temperatures of 773 and 1073 K. All the experiments were conducted in a fixed-bed/fluidised-bed quartz reactor. The results show that high heating rate and high temperature have substantially promoted the formation of both NH 3 and HCN. By comparing the results from raw coal and acid-washed coal, it was found that reduction in AAEM (mainly Na and Ca in this case) could lead to less production of NH3, but more formation of HCN.
