碱化甘蔗渣制备型煤黏结剂的研究

传统甘蔗渣利用率低,不仅浪费资源,还污染环境,因此研究甘蔗渣的再利用对于保护环境、创造经济增长点具有重要意义。试验以NaOH碱化甘蔗渣为型煤黏结剂,研究了NaOH质量分数、加热时间、加热温度对型煤抗压强度和跌落强度的影响。结果表明:利用甘蔗渣制备型煤黏结剂的最佳条件为:NaOH质量分数3%,加热时间2 h,加热温度85℃;此时制备的型煤抗压强度为440.5 N/个,跌落强度78.2%。因此,利用甘蔗渣制备型煤黏结剂是对甘蔗渣利用的新尝试,经NaOH碱化的甘蔗渣稳定性好,制得型煤的抗压强度和跌落强度均较高,改善和保护环境的同时,增加了经济效益。 The ratio of traditional bagasse utilization is low,not only waste resources,also pollute the environment,so the study of bagasse efficient utilization is important for environmental protection and economic growth.Briquette binder was prepared via alkalizing bagasse using NaOH.The influence of NaOH concentration,heating time,heating temperature on compressive strength and drop strength were studied.The optimal preparation condition is,NaOH concentration is 3 percent,heating time are 2 h,heating temperature is 85 ℃,the compressive strength and drop strength of briquette can reach up to 440.5 N and 78.2 percent.Preparation of briquette binder is a new attempt to use bagasse,its stability becomes better by alkalizing with NaOH
