공업용 촉매(ICI57-4M)의 CH₄ 수증기 개질반응속도를 550-650℃, 전압 1-5atm의 조건에서 흐름 반응기를 사용하여 조사하였다. 반응속도식을 얻기 위한 실험은 반응기 입구의 CH₄, H₂ 및 H₂O의 분합을 조정하여 행하였다. 수소분압과 반응온도에 따라 수소의 저해효과가 있는 반응속도식과 그 효과가 없는 다음의 두 가지 반응속도식이 주어졌다._x000D_ -r=2.4×10¹¹exp(-45300/RT) [P₅-(P₃+P₄)(1-X_e)/X_e]/P₁_x000D_ -r=2.3×10⁸exp(-32000/RT) [P₅-(P₃+P₄)(1-X_e)/X_e]_x000D_ 수소 재해효과는 수소분압이 클 때 관찰되었으며 반응온도가 증가함에 따라 수소 저해효과가 시작되는 수소분압이 증가하였다. 또한 실험결과의 분석에 적용되는 반응속도식에 따라 계산된 활성화에너지와 반응속도에 미치는 반응물들의 영향에 대한 해석이 많이 달라질 수 있음을 보였다.

The kinetics of the methane steam reforming reaction over an industrial catalyst(ICI 57-4M) was investigated at emperatures 550-650℃ and at total pressures 1-5atm in a flow reactor. The experiments were performed by varying the inlet partial pressure of methane, hydrogen, and water. Depending on hydro-gen partial pressures and reaction temperatures, the following two rate equations, one with the hydrogen inhibition effects and the othe without the effects, were given:_x000D_ -r=2.4×10¹¹ exp(-45300/RT) [P₅-(P₃+P₄)(1-X_e)/X_e]/P₁_x000D_ -r=2.3×10⁸ exp(-32000/RT) [P₅-(P₃+P₄)(1-X_e)/X_e] _x000D_ The hydrogen inhibition effect was observed at high hydrogen partial pressures, and with increasing reaction temperature, the hydrogen partial pressure above which the inhibition effect became significant has increased. Depending on the rate expressions chosen for the analysis of the data, it was also shown that the activation energies and the interpretation on the role of the reactant species involved could be widely different.
