低共熔溶剂预处理棕榈壳微波热解制备碳纳米管
Preparation of carbon nanotubes by microwave pyrolysis of palm kernel shell pretreated with deep eutectic solvents
摘要
Abstract
As a rich renewable energy source,the graded conversion and efficient high-value utilization of wood cellulose biomass contribute to the achievement of China's"dual carbon"goals.Palm shells are a common waste material,which is rich in cellulose,lignin and other substances.In this paper,the palm kernel shell(PKS)as the raw material was pretreated with deep eutectic solvents(DESs)to obtain cellulose components,and carbon nanotubes were directly prepared using the microwave pyrolysis device.The pretreatment process parameters of palm shell were opti-mized by BBD(box Behnken design)response surface methodology,and the pyrolysis products were analyzed by scan-ning electron microscopy(SEM),high-resolution transmission electron microscopy(HRTEM),X-ray diffraction(XRD),Raman spectroscopy(Raman),thermogravimetric analysis(TGA)and other methods.The results show that when the pretreatment temperature is 120℃,the pretreatment time is 3 h,and the hydrogen bond donor molar ratio was 1∶5,the removal rate of lignin is the highest and the yield of cellulose is the highest.The optimization results of process parameters show that the degree of influence of pairwise interactive influencing factors on the remo-val rate of lignin from pretreated palm shell is ranked as follows:pretreatment temperature>hydrogen bond donor molar ratio>pretreatment time.Palm shell cellulose can be thermally decomposed by microwave to produce struc-turally intact carbon nanotubes in one step.关键词
