Adsorption Temperature

The Mn loaded ACF (ACF-Mn), prepared by impregnation method combined with activation method under high temperature, can be used to adsorb the low concentration SO2. The modified ACF was characterized by iodine value and functional groups. The adsorption properties of low concentration SO2 on ACF-Mn-Cu50 were also studied. The result showed that the adsorption properties were improved with the granular Cu. Amount of Mn particles attached to the surface of ACF and the desulfurization rate of ACF-Mn-Cu50 both increased after second modification when the adsorption temperature was 60°C, the air velocity was Q1=0.3 L/min and Q2=0.4 L/min respectively and the concentration of SO2 was 0.62×10-4 μg/ml.

Surface Modified

Activated carbon fiber (ACF) was used as a model of commercial activated carbons to examine the effect of surface chemistry on the attachment behavior of bacterial biomass. Surface acidity was found to enhance the biomass-ACF interaction. When ACFs were applied as biomass support media in a continuous stirred tank reactor, surface acidity of the carbon resulted in faster biomass growth in the start-up phase. The start-up phase was simulated by a simple biomass attachment kinetics model. Experimental and calculated data show a reasonable agreement, with the exception of the hydrogenated specimen, which was interpreted by assuming that the hydrogen-reduced surface is highly reactive and then may undergo oxidation in the initial phase of operation so that the adsorption characteristics are altered.
