摘要
利用自行设计的新型煤气化炉,实现了不同碳质原料的气化实验.分析了气化对载能材料的纯度、晶体形态及产量的影响,研究了烟煤的高温孔隙结构和焦炭的高温表面碳微粉对6H-SiC多型含量的影响,指出气化对载能材料质量无影响,烟煤高温孔隙率高、断面结构复杂及烟煤焦炭的高温表面碳微粉是造成6H-SiC多型含量高的主要原因.
Self-inventing new coal gasification furnace is used to complete gasified experi- ment of varied carbonaceous material. The effects of gasification on purity, crystal morphosis and yield of energy carrier material were analysed. The effects of micro-porosity of bituminite at high temperature and fine powdered carbon in the surface of coke at high temperature on the content of 6H-SiC were studied. It is found that new coal gasification has no effect on the quality of energy carrier material and the high porosity, complexed sectional structure and fine powdered carbon in the surface of coke at high temperature are main reasons for the high content of 6H-SiC.
