摘要
随着木材加工行业的快速发展,松木废屑的大量产生带来了资源浪费与环境污染问题。本研究以松木废屑为原料,通过高温炭化和磷酸活化法制备了松木基生物炭,并通过热重、扫面电子显微镜、元素分析、傅里叶红外光谱和BET比表面积等表征方法系统分析了以松木废屑为原料制备生物炭的机理及理论工艺参数。研究结果表明,松木富含C、O、Si三种元素,且其自有的管状结构为制备高性能生物炭提供了有利的活化通道,且磷酸活化有利于提高松木废屑的收率,制备的生物炭比表面积达1090.245 m^(2)·g^(-1),总孔容0.412 cm^(3)·g^(-1),平均孔径3.087 nm。本研究不仅为松木废屑的资源化利用提供了新的思路,也为生物炭在环境治理和能源领域的应用拓展提供了理论支持与实践指导,具有重要的环境和经济价值。
With the rapid development of wood processing industry,the large amount of pine waste brings the waste and environmental pollution.Taking pine scrap as raw material,pine biochar was prepared using high temperature carbonization and phosphoric acid activation method.Through the thermal weight,scanning electron microscopy,element analysis,fourier infrared spectroscopy and BET specific surface area characterization method,the preparation of pine scrap biological carbon mechanism and theoretical process parameters were analyzed.The results showed that pine was rich in C,O and Si,and its own tubular structure provided a favorable activation channel for the preparation of high performance biochar,and phosphoric acid activation was beneficial to improve the yield of pine scrap.The specific surface area reached 1090.245 m^(2)·g^(-1),the total pore capacity was 0.412 cm^(3)·g^(-1),and the average pore diameter was 3.087 nm.This study not only provided a new idea for the resource utilization of pine scrap,but also provided theoretical support and practical guidance for the application of biochar in environmental governance and energy field,which had important environmental and economic value.
