Determination of sulfur capacity (hydrogen sulfide) for Coal Based Activated Carbon
Under certain experimental conditions, the porous nature of activated carbon is utilized to adsorb hydrogen sulfide gas. In the presence of oxygen and ammonia, a catalytic reduction reaction occurs, and the precipitated elemental sulfur adheres to the activated carbon until adsorption saturation is reached.
Penetration sulfur capacity measurement is the process of using the porosity of activated carbon to adsorb a certain concentration of hydrogen sulfide gas under certain experimental conditions. When the concentration of hydrogen sulfide gas passing through the activated carbon sample layer reaches a volume fraction of 50 × 10- ⁶, the mass of hydrogen sulfide gas adsorbed per gram of activated carbon during this period is the penetration sulfur capacity of activated carbon.
The sulfur capacity mainly characterizes the desulfurization performance of activated carbon in the flue gas purification process.
