Abstract An experimental technique of pure sulphidation in reducing H_2S-H_2 environment has been investigated. Equilibrium of two reactions H_2+1/2O_2=H_2O and H_2S=H_2+1/12S_2 can be reached by the apparatus employed through ceful control of the flow rate, i. e. the total flow rate of H_2S plus H_2 is kept lower than 60Oral/min. Under such a condition, oxygen partial pressure at the sample is very low. While the sulphur partial pressure can be accurately controlled within the range of 10~(-2) atm-10~(-10) atm by carefully regulating and controlling the flow rates of H_2S and H_2 respectively. Experiments demostrate that corrosion products are pure sulphides without oxides. It is feasible and reliable to study sulphidation by this technique.
