| 摘 要： | 为了达到废印刷电路板(WPCB)热解油的脱溴和轻质化的目的,在废印刷电路板非金属粉末(WPCBNP)的热解中应用不同的添加剂(脱溴剂、脱溴剂+催化剂).首先,研究了WPCBNP的热解三相产物产率.其次,测定了热解液体产物中有机溴和无机溴的含量.最后,分析了热解油中碳原子的组成分布和组分含量.试验结果表明,使用Fe_3O_4+4A分子筛时,热解油回收率可达12.23%.热解液相产物中的无机溴含量从283.04 mg·g~(-1)减少到10.19 mg·g~(-1)(Fe_3O_4+Al_2O_3),去除率为90.47%,有机溴含量从151.13 mg·g~(-1)减少到11.07 mg·g~(-1)(Fe_3O_4+Al_2O_3),去除率分别为90.47%和92.68%.应用Fe_3O_4+Al_2O_3可将C6~C9组分(或汽油组分)含量从61.07%提高到76.75%,C10~C14组分(或柴油组分)含量从10.66%提高到13.95%,而≥C15(或重油组分)含量从28.27%降低至9.30%.通过分析热解油成分,可知油中主要含溴有机物是2-bromoPhenol和2,4-dibromo-Phenol.应用不同添加剂/组合添加剂,2-bromo-Phenol含量可降至1.22%,而2,4-dibromo-Phenol未被检出.结果表明,Fe_3O_4+Al_2O_3在WPCBNP热解油的脱溴和轻质化方面效果最好,对WPCB资源化利用具有显著的效益.
