摘要：农林废弃生物质与煤共气化通过充分利用两者的相似性和互补性,实现原料转化过程的节能、低碳、清洁高效。原料灰渣的理化特性是影响共气化稳定运行的关键因素之一,成为了共气化研究关注的重点。本综述主要从农林废弃生物质灰与煤灰的共性与差异、混合灰渣熔融与黏温特性、混合灰中碱/碱土金属对共气化反应性和结渣过程烧结行为的影响等方面,梳理了世界各国农林废弃生物质与煤共气化灰渣理化特性的研究现状。总结分析了添加农林废弃生物质对混合灰熔融流动、烧结行为的影响机制,归纳了混合灰熔融特征、黏温及结渣特性的预测模型与方法,并提出了农林废弃生物质与煤共气化灰渣的未来研究重点。
Co-gasification of agroforestry waste biomass and coal realizes energy-saving,low-carbon emission,clean and efficient raw material conversion by taking advantage of their similarities and complementarities.The physicochemical properties of ash slag for raw materials are one of the key factors affecting the stable operation of co-gasification.It is the focus of co-gasification research.This paper reviews the research status of physicochemical properties of ash slag from co-gasification of agroforestry waste biomass and coal.It mainly includes the similarity and difference between agroforestry waste biomass ash and coal ash,the fusion and viscosity-temperature characteristics of mixed ash,the effect of alkali/alkaline earth metals in mixed ash on co-gasification reactivity,and sintering behavior during the slagging process.The influence mechanism of adding agroforestry waste biomass on the melting flow and sintering behavior of mixed ash is discussed.The prediction models and methods of fusion characteristics,viscosity-temperature,and slagging characteristics of mixed ash are also summarized.Finally,the future research directions of ash slag from co-gasification of agroforestry waste biomass and coal are proposed.
