    Abstract
  • A self-made experimental system was used to study the catalytic oxidation of low-concentration coal mine gases to methanol in acetic acid solution.With Pd(OAc)2 as catalyst, addition of p-benzoquinone or chloranil in the reaction system provides a beneficial environment for activation of methane, and chloranil shows a more positive effect.Chloranil amount and reaction temperature and pressure are the key factors influencing the catalytic properties.The target product yield has a positive relationship with these three factors.CH3OH is formed from the reaction of generated H2O2 and CH4.CH3COOCH3 is generated via two routes;one is direct oxidation of Pd2+ and CH4, the other is esterification of CH3OH and CH3COOH.
