摘　　要：苎麻作为我国的特产,长期以来人们对占90%以上的麻骨等副产品没有很好利用。苎麻麻骨的化学成分符合制备炭材料所需原料的基本要求,以苎麻骨炭为载体进行碱性负载制备出固体碱催化剂。采用苎麻骨制备碱性负载固体催化剂,IR和XRD分析表明,引入的负载物KF、Na2SiO3等可能是以无定形态吸附在炭的孔隙中,所得催化剂对PET具有显著的降解效果,降解率可达100%,降解产物为BHET。醇解废弃PET材料,实现资源的再利用。Ramie is an important textile fibers crops in our country. There are more than 90% accounts of the ramie bone byproduct bar that can not be well used. The ramie bone is fitted to prepare fbr the activated carbon according to its chemical composition, and the ac- tive carbon can be used as the carrier to load the alkaline solid alkali to obtain catalyst. In this paper, solid catalysts based on the ramie bone are prepared and characterized by IR and XRD analysis. It shows that the load KF or Na2SiO3 may be adsorbed in the pores of amorphous carbon obtained from ramie bone. The catalysts are significant degradation for PET with 100% degradation rate. The degradation products are BHET. We can re-use ramie bone resources by alcohol of the waste PET material.
