摘要
综述了铁元素对褐煤热解及气化的影响方面的研究进展,在褐煤中植入铁元素对褐煤热解和气化的半焦产物、气体产物的影响,分析了铁在褐煤热解和气化过程中的迁移和转化,并与褐煤中植入的其他金属元素产生的影响进行了简单对比。
Poly-generation system based on coal pyrolysis and gasification is one of the options of clean and efficient utilization of coal in China. In this paper, an overview of current status and progress of studies on the effects of iron loading on the pyrolysis and gasification features of brown coals upon heating has been provided with the changes in char and gaseous products because of iron-loading were summarized. The transformation of iron species during pyrolysis and gasification processes is discussed. The effect of iron-loading is also compared with that of oth,r metals loaded iuto the brown coal.
