ANALYSIS OF THE REMOVAL OF H_2S WITH IMPREGNATED ACTIVATED CARBON

摘要

A general mathematical model with its governing equations in dimensionless forms has been developed to describe the removal of hydrogen sulfide with impregnated activated carbon. An approximate relationship between the sulfur capacity and the reaction time in a single carbon pellet is obtained, and criterion to ascertain the rate controlling step of the process can then be deduced. In the meantime, the choice of the appropriate oxygen concentration and the principle to be followed are also described.
