环境科学技术 解聚 Depolymerization of PS in supercritical benzene was also carried out at temperature ranging from 300-360℃, at different pressures of 4.5-10.7MPa, at reaction time of 10-50min, respectively. 此外,以苯作为解聚介质(临界温度为289.0℃,临界压力为4.90MPa),在温度300~360℃、压力4.5~10.7MPa及时间10~50min的条件下对聚苯乙烯颗粒进行解聚实验研究。 降解 In this research, a SCF reaction system was re-designed and constructed. The depolymerization behavior of high density polyethylene (HDPE) in supercritical water and effect of an additive, benzoyl peroxide (BPO) were studied. 本文自行组装和改进了一套超临界流体反应装置,并且使用这套装置开展了对高密度聚乙烯(High density polyethylene, HDPE)在超临界水中的降解行为和添加剂——过氧化苯甲酰(benzoyl peroxide,BPO)对该降解反应影响的一系列实验。
