Simultaneous Removing COS and H2S by Using Activated Carbon Fibre in Feedstock of Carbon Dioxide

FANG Lei1,ZHANG Yong-chun1,ZHOU Jin-xia1,DING Wei2(1.State Key Laboratory of Fine Chemical,Dilian University of Technology,Dalian 116012,China)(2.Academy of Dilian University of Technology,Liaohe Petroleum Exploration Bureau 124010,China)  
The activated carbon fibres were modified with some alkali and ions such as NaOH,KOH,Na2CO3,K2CO3 and Co2+,Fe3+ by the impregnation method and some factors which may affect the performance of removing COS and H2S such as kinds and concentration of alkali and metal ions,the components of feed gas,and reaction temperature were investigated on the fixed-bed reactor.The results showed that the activated carbon fibres modified with alkali had a higher sulfur capacity than the modified activated carbon fibres,and the activated carbon fibres modified with metal ion had a higher sulfur capacity than other modified activated carbon fibres.In addition,the activated carbon fibres modified with Co2+ had a better efficiency of simultaneous removal of COS and H2S than the others.
