将大量粒径小于3mm的废弃兰炭粉末制气化型煤既可以降低气化型煤的成本，也充分利用了资源。本文采用常温加压成型工艺，重点研究了不同黏结剂对型煤性能的影响，并考察了添加阻熔剂后兰炭灰渣熔点的变化情况。结果表明，在相同添加量下，有机黏结剂制备的型煤落下强度大，但热稳定性差；而以无机黏结剂制备的型煤落下强度小，影响型煤热值，但热稳定性好。黏土1（wAl2O3>60%）既有黏结性能，又能很好地提高煤灰熔融特性。将腐殖酸钠、淀粉、黏土1复合黏结剂可以使兰炭型煤落下强度和灰熔点满足气化型煤的要求。

A large quantity of semi-coke powder with particle size less than 3mm are used to make gasification briquette,which can not only reduce the cost of gasification briquette,but also make full use of resources. Briquette coal is molded at room temperature and under pressure. This paper focuses on the influence of different binders upon the properties of briquette coal and the change of ash melting temperature of semi-coke when refractory agent is added. With the same amount of binder,the briquette coal with organic binder has higher falling shatter strength and higher calorific value than that with inorganic binder,but its thermal stability is poor. Clay 1 (wAl2O3>60%) not only has bonding capability,but also increases the melting point of coal ash. The composite binder,containing sodium humate,starch,clay 1,can make the falling shatter strength and ash melting point of semi-coke meet the requirements of gasification briquette.
