Abstract
We prepared sodium carbonate impregnated activated carbon fiber and evaluated its availability for hydrogen sulfide removal by the comparison with the counterpart, sodium carbonate granular impregnated activated carbon. The sodium carbonate impregnated concentration and immersion duration were chosen as two primary parameters. First, the hydrogen sulfide adsorption capacity increased in proportion to the impregnated concentration up to 3 wt%, above which the sodium carbonate impregnated amount rarely showed an increase due to the pore filling effect for both cases. The optimal impregnated concentration was thus set to 3 wt%. Meanwhile, impregnated activated carbon fiber required only half of the immersion duration compared with granular impregnated activated carbon, while showing a 30% increase on the hydrogen sulfide removal capacity. The greater specific area of impregnated activated carbon fiber explained it. In conclusion, we evaluated advantage of preparation time and improved hydrogen sulfide adsorption capacity by impregnate sodium carbonate, which is capable of reacting with hydrogen sulfide chemically, onto the activated carbon fiber with improved specific area.
