英文摘要：

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.
