INFLUENCE OF H 2S ADSORPTION AND CONVERSION BEHAVIOR OVER ACF ON NANO SPACE OF ACF

The adsorption and conversion of hydrogen sulfide (H 2S) over ACF relate to a modification of the nano space structure of ACF. After the process, pore structure and surface micro structure make certain modifications, which retain even at higher temperature(350℃). As for pore structure, the ultramicropore volume decreases in the course of the adsorption and conversion process.After adsorption, some sulfur containing complexes, resulted from H 2S conversion, retain in micropore surface very stably, and can be removed only at higher temperature. Meanwhile, other surface complexes change to new chemical states due to the interaction between H 2S and these complexes. In all, the adsorption and conversion of H 2S create a nano space of new adsorption and catalytic properties.
