摘　　要：粘结剂对生物质颗粒燃料结渣率有显著影响,并通过以木质素为基体,通过解聚、羟甲基化、胺化制备高性能的粘结剂,并通过与高岭土等无机矿物质复合来改善生物质颗粒燃料物理性能及易结渣的特性。结果表明:胺化木质素/高岭土为7∶3(wt%)时,生物质颗粒燃料的抗跌碎强度达95.67%,真实密度为0.97 g/cm^(3),结渣率下降到14.2%,相比只添加胺化木质素粘结剂的颗粒燃料的结渣率下降了42.51%。该复合粘结剂具有粘结强度高、抗结渣性好等性能,且成本低、工艺简单和环境友好等特点。The binder has a significant effect on the slagging rate of biomass pellet fuel.High-performance binder was prepared by depolymerization,hydroxymethylation and amination using lignin as the matrix,and the composite binder was constructed by combining the preparedbinder with inorganic minerals such as kaolin to improve the physical properties and slagging characteristics of biomass pellet fuelThe results showed that,when compounding kaolin with aminated lignin binder at the mass ratio of 7∶3(wt%),the composite binder also showed excellent performance.The crushing strength and the true density of biomass pellet fuel were 95.67%and 0.97 g/cm^(3),respectively,and the slagging rate drops to 14.2%,which decreased by 42.51%compared with that of pellet fuel with amine lignin binder only.The composite binder has high bonding strength,good slagging resistance,low cost,simple process and environmental friendliness.
