Impregnated activated carbon removes gaseous pollutants like Hydrogen sulfide can be effectively captured by impregnated activated carbon and converted to sulfur. Impregnated activated carbon removes gaseous pollutants via an irreversible reaction between the additives and pollutants. Hydrogen sulfide can be effectively captured by impregnated activated carbon and converted to sulfur when the operation temperature is between 24–170◦C.
Activated carbon impregnated with NaOH solution was shown to have the optimum H2S removal efficiency. H2S adsorption via Alkaline RXSOL CARBON was five times that of a corresponding fresh activated carbon.
The adsorption equivalent of H2S is nearly 1 (mol-H2S/mol-AOH). Which can be easily understood with this reaction H2S + AOH → AHS + H2O
Our experiment shows that adsorption capacity of activated carbon directly affected by specific surface area, pore size distribution, pore volume, and surface functional groups.
Hydrogen sulfide generated/emitted by petrochemical plants, food plant, processing plants, semiconductor plants, sewage treatment plants, or pharmaceutical plants. Generally, the effluent gases from such plants are treated by washing followed by neutralization with chemicals, adsorption onto activated carbon, condensation, masking, or direct or catalytic combustion. RXSOL impregnated activated carbons have been developed with superior deodorizing performance.
Impregnated Activated carbon are manufactured by carbonization of char - coal in the presence of activating agents such as CO2 or steam. And during Chemical activation following chemical agents used in the chemical process are normally alkali and alkaline earth metals or acids such as KOH, K2CO3, NaOH, Na2CO3, AlCl3, ZnCl2, MgCl2 and H3PO4 etc.
There are several impregnation solutions that may increase the adsorption capacity of H2S such as methulol-melamine-urea, n-butylamine, and urea. The adsorption capacity of H2S on impregnated activated carbon may be increased up to 1.5 times the value of raw activated carbon. Have used N-containing activated carbon to adsorb hydrogen sulfide and dimethyl sulfide.
