摘要:
选取浙江省宁波市本地适合制备生物炭的6种农业废弃物原料,采用不同热解条件制备获得生物炭,对自行制备的生物炭及大米加工副产物稻壳炭的成炭率、pH值、元素含量、比表面积和孔结构进行分析。结果表明,不同原料及热解条件下生物炭的产率分布在19.50%~45.40%之间,pH值为8.52~10.85,碳含量在432.50~778.62 g/kg 之间,其他元素含量在不同原料之间有所不同。自行制备生物炭的比表面积分布在1.01~7.63 m2/g之间,微孔面积分布在未检出~4.81 m2/g,低于稻壳炭的比表面积(48.35 m2/g)和微孔面积(24.06 m2/g)。扫描电镜(SEM)图显示自行制备的生物炭为蜂窝状孔隙结构,稻壳炭为网纹孔隙结构。
