摘　　要：随着废弃香烟过滤嘴(UCF)产生量的逐年增加,其高效处理和转化成为了研究热点.本研究以UCF的资源化利用为目的,通过微波辅助热解方法实现其高效转化.利用红外光谱法(FTIR)、气相色谱-质谱联用法(GC-MS)等手段对其热解液体产物生物油进行了分析,利用场发射扫描电子显微镜(FE-SEM)以及氮气吸附法(BET)对其热解固体产物生物炭进行了分析.结果表明,UCF热解生成的生物油产率为48.28%,生物油中的酯类、芳烃类、酚类和醚类相对含量明显提高.UCF热解生物油中乙酸甲酯的选择性高达53.86%.UCF生物炭具有较高的比表面积(316.7 m2/g)和介孔孔隙结构(4.24 nm),表明其在吸附、催化、电化学等领域有一定的应用潜力.将为UCF的减量化和高值化利用提供了一种新途径.With the increasing production of used cigarette filter(UCF),its efficient treatment and conversion has become a research hot topic today.This study is aimed to efficient conversion of UCF(used cigarette filter)into value-added chemicals by microwave-assisted depolymerization method.The liquid product of bio-oil was analyzed by FTIR and GC-MS.The solid product of bio-char was characterized by FE-SEM and BET.Results showed that the yield of bio-oil obtained from UCF was 48.28%.The esters,aromatics,phenols and ethers in bio-oil showed the high selectivity.The selectivity of methyl acetate in bio-oil reached to 53.86%.UCF bio-char presented high specific surface area(316.7 m2/g)and mesoporous pore structure(4.24 nm),which indicated that it has certain application potential in adsorption,catalysis and electrochemistry.This study will provide a new way for the reduction and high value utilization of UCF.
