摘要
借助扫描电子显微镜研究了原煤及其各种树脂混合物经微型反应釜中350℃和400℃处理后所获残炭的形貌。结果表明:富氢煤的显微组分被分解,而丝炭和角质等煤的显微组分难分解。添加诸如高密、低密聚丙烯及聚苯乙烯等树脂后可加速煤的显微组分的分解,并改变了其残炭的显微形貌。
Carbonaceous residues obtained by carbonizing virgin and various coal-polymer mixtures in a micro autoclave at temperatures of 350℃ and 400℃ were investigated by scanning electron microscopy. Results show that hydrogen-rich macerals are disintegrated while other macerals like fusain, and exinite are resistant to disintegration. Addition of polymers like low & high density polypropylene and polystyrene leads to an increased disintegration of the macerals and alters the morphologies of the residues.
