摘要：

For the first time, a mechanistic study of methane oxy-steam reforming and LNG (OSR-LNG) processes is presented using Fourier transform infrared (FTIR) spectroscopy. The FTIR measurements were carried out in the temperature range of 200-600 degrees C in the tested processes. The reaction mechanisms of oxy-steam reforming of CH4 or LNG were proposed from the results obtained. It was found that the dissociation of methane into carbon-containing molecules and/or into carbon molecules adsorbed on the catalyst surface is a crucial step in determining the reaction rate. The results can be used to design catalytic systems for natural gas reforming.
