负载CeO2的改性活性炭吸附脱硫性能研究
Study on absorptive desulfurization performance of modified activated carbon loading CeO2
摘要
Abstract
Ceria-loaded carbon was prepared by dipping-calcining method,and its absorption capacity to dibenzothiophene (DBT) in model fuels was tested. The adsorbents and original materials were also characterized by means of nitrogen adsorption,FTIR,and Boe-hm titration. The results show that the optimal ceria loading capability of activated carbon is 1.29 % ( mass fraction), the maximum adsorption capacity of the sample to DBT was calculated according to Langmuir model,and it is nearly 139.2% of the adsorption capacity . of the original activated carbon. The texture and surface chemistry analysis of the modified activated carbon show that the improvement of its absorption capacity is mainly due to the increase of acidic sites on the adsorbent surface and the interaction between cerium ion and dibenzothiophene.关键词
