Abstract  

Chronoamperometry(CA) was used to study the melt interface reaction in H2S/CO2 coexistence environment. The mathematic model for interface reaction of the process has been carried out. The action of adsorption, desorption and hydrogen absorption for interface reaction were analyzed using this model. The results demonstrated that when η=50 mV, the process of hydrogen adsorption is dominant and control whole interface reaction; when η>50 mV,the desorption process of pre-adsorption substance control whole interface reaction. CO2 increases contribution of absorption-feature hydrogen to the itotal,so promotes hydrogen absorption in all experimental η condition.

Key words:  H2S/CO2 coexistence environment      adsorption reaction      desorption reaction      chronoamperometry
