【摘要】 通过对煤在电弧等离子体中的热解行为和煤与活性物种的作用机理探讨，提出煤与电弧等离子体的作用是煤在等离子体中的热解、煤中的碳与活性物种、煤分子结构中的化学键和活性物种，以及热解挥发物和活性物种的综合作用结果。在氢电弧等离子体中，每种作用对煤转化及产物的生成都有贡献，然而作用机理不尽相同。其中氢原子在煤转化的过程中起了很重要的作用。更多还原

【Abstract】 The pyrolysis of coal and the interaction mechanism of coal with active species are discussed in this paper.It is put forward that the interaction of coal with plasma is the combination of them.The interaction of coal with plasma active species mainly consists of coal pyrolysis,that of carbon in coal with active species,that of bond in coal chemical structure with active species and that of primary volatile with plasma active species.Every one has contribution to the coal conversion and generation of hydrocarbon,while their mechanisms are different.It seems that the hydrogen atom plays a very improtant role in the process. \ \更多还原
