An assumption could be derived from the variation of coal-char sizes that there maybe exist an optimal coal-char size range that made abundant porosity and bigger pore specific areas to enhance the gasification reaction.
在一定的气化工况下,煤焦可能存在一个合适的颗粒尺寸范围,使得挥发分的析出比较彻底,煤焦气化反应进行得比较充分,半焦颗粒的比表面积、孔比表面积和孔容积都能得到充分的发展。
