ABSTRACT

Among other filters such as light filter, wave filter, air filter, ultra filter and filter paper, a novel adsorption filter from thermostable polyester nonwoven fabrics immobilized with functional super activated carbon by means of quinoline soluble, activateable isotropic pitch binder were developed in this study. The activated carbon precursor is available in the market branded as coconut shell based activated carbon(CCS-AC) produced by Dongyang Carbon Co. Ltd. BET-surface area of this precursor was 1,355 m2/g, after KOH-activation it increased over 2,970 m2/g and was named as super activated carbon. In the preliminary research, this precursor was impregnated with PdCl2(0.188 wt%) KMnO4(3 wt%) and redox-agent(CuCl2, 0.577 wt%) in order to promote TOF up to 100/h and Selectivity up 99% and patented as a functional AC for the ethylene adsorption. The enhancement of the isotropic pitch binder to the AC-immobilized adsorption filter was BET-surface area upgraded by 266 m2/g and promoted the Iodine- and MB-adsorption by 1.4 times, respectively and also micro pore wide ranges <5Å~30 Å>.
