2)  micro-pulverized coal
超细化煤粉
1.
In this paper, firstly, each of five kinds of mineral substances (NaOH, MgO, CaO, Al_ 2 O_ 3 and Fe_ 2 O_ 3 ) was mixed into three kinds of deashed micro-pulverized coals (obtained from Hegang, Tiefa, Zhungeer) to make experimental samples for the combustion experiments, respectively.
结果发现,经脱灰处理的超细化煤粉在氧气体积分数为20%时燃烧过程中NO的释放曲线是单峰曲线;NaOH、Al2O3对NO的还原反应均表现出不同程度的催化作用,NaOH的催化能力最强;Fe2O3、CaO和MgO对还原反应有催化或抑制作用,其作用的类别和大小与煤的种类和矿物质的含量有关,超细化可促进NO的还原。

性质:非水溶性染料或不易溶染料常采用的剂型。如分散染料、还原染料等对粒度及粒度分布均有一定要求,要求相对集中,过细、过粗,均对使用有不良影响。染料生产企业对本企业的产品均作了规定。这些染料产品一般多在2μm到上到4μm范围内,如对某些分散染料要求控制在1μm左右,分散性能4~5级,还原染料也与分散染料近似,故有超细粉之称。为使染料产品达到上述细度,常采用万能粉碎机或砂磨、球磨等进行粉碎。
