石油焦系超级活性炭的孔结构控制
Structure modification of ultra activated carbon from petroleum coke
摘要
Abstract
Heat treatment (HTT), chemical vapor deposition (CVD) and HNO3 oxidation were employed to modify the surface and pore structure of ultra activated carbon (UAC) prepared from Daqing petroleum coke using KOH as an activating agent. It was found that the surface area and mesopore ratio of carbon source. The UAC modified by CVD also show an enhanced molecular sieving capability manifested by enhanced adsorption for CO2 over CH4 from oxidation, and the number of carboxyl functional groups on the surface of UAC after HNO3 oxidation for 60min is about 9 times as much as that for 20min oxidation.关键词
