摘要
以聚乙烯(PE)这一广泛应用的塑料为例,从降解机理出发,综述了工艺条件包括温度、压力、停留时间、溶剂种类和溶剂/塑料(S/P)质量比对降解产物分布的影响.此外介绍了目前见诸报道的工业化装置,并展望了未来的研究方向.
Abstract
This paper reviewed the research progress in the influence of process conditions,including temperature,pres-sure,residence time,solvent type,and mass ratio of solvent to plastics,on the distribution of degraded products from the aspect of its degradation mechanisms by taking a widely used thermoplastic,polyethylene,as the example.In addi-tion,the industrialization devices reported currently for solvothermal liquefaction degradation were introduced,and the future research direction was prospected.
