摘要

以一种全新的物质——阻燃的FR-1型酚醛树脂电路板基板的真空热解炭渣为原料

采用CO2和KOH活化法制备高性能的活性炭。分别研究了CO2活化法中的活化温度和KOH活化法中的碱炭比对活性炭产品性能的影响。用氮气吸附表征了活性炭的孔结构性质

并检测了产品的亚甲基蓝值和碘值。结果表明

KOH活化所得活性炭有更高的亚甲基蓝值(928.3 mg·g-1 vs 231.5 mg·g-1)、碘值(2442.2 mg·g-1 vs 946.6 mg·g-1)、比表面积(2289 m2·g-1 vs 1198 m2·g-1)和孔体积(1.317 cm3·g-1 vs 0.703 cm3·g-1)。所得产品均达到国家一级品标准。用这种原料制备高性能活性炭不仅解决了废弃物资源化的问题

还开发出一种新的、廉价的制备高性能活性炭的原料和方法工艺。

Abstract

Vacuum pyrolysis residue of flame retardant FR-1 phenolic resin laminated board was used to prepare high quality activated carbons(ACs)by CO2 and KOH activation

respectively.The effects of activation temperature by CO2 activation and KOH/char ratio by KOH activation on the properties of obtained ACs were investigated.The pore structures were characterized by N2 adsorption.Methylene blue(MB)and iodine(I2)adsorption capacities were also measured.The results showed that ACs obtained by KOH activation had a higher I2 adsorption value(2442.2 mg穏-1 vs 946.6 mg穏-1)

MB adsorption value(928.3 mg穏-1 vs 231.5 mg穏-1)

specific surface area(2289 m2穏-1 vs 1198 m2穏-1)

and larger total pore volume(1.317 cm3穏-1 vs 0.703 cm3穏-1).All the products reached the national first class standard.A double benefit may be obtained by this study

for it not only achieves the purpose of utilization of pyrolysis residue of waste printed circuit board

but also finds a novel and cheap material for the preparation of high quality ACs.
