Abstract Fast pyrolysis of pulverized coals (Highly Volatile Bituminous C-(HVBC) and Semi-anthracites (SA)) were studied in a novel hot plate reactor (HPR). The combined effect of the heating rate (HR) and the reaction environment inside the reactor on chars structure were detailed analyzed. The iso-conversional Flynn–Wall–Ozawa (FWO) methodology was utilized to study mass loss during fast pyrolysis of both coals. It was found that, at high HR, the mass loss rate during pyrolysis and the degree of microstructural ordering reached by the chars strongly depend on secondary reactions between carbonaceous structures, the volatiles and the reaction atmosphere.

新型热板反应器中煤颗粒的快速热解：反应气氛对反应性和炭化学结构的影响

摘要 在新型热板反应器 (HPR) 中研究了粉煤（高挥发性烟煤 C-（HVBC）和半无烟煤（SA））的快速热解。详细分析了加热速率（HR）和反应器内反应环境对炭结构的综合影响。等转化 Flynn-Wall-Ozawa (FWO) 方法被用来研究两种煤在快速热解过程中的质量损失。结果表明，在高 HR 条件下，热解过程中的质量损失率和炭达到的微观结构有序程度在很大程度上取决于碳质结构、挥发物和反应气氛之间的二次反应。
