Influencing factors for catalytic oxidation of mine gas to methanol in liquid phase

The influencing factors for liquid phase catalytic oxidation of mine gas to methanol (in form of CH₃COOCH₃) are studied using the self-established experimental apparatus. The results show that CH₃COOCH₃ (target product) is obtained by using CH₃COOH as reaction solvent, and the yield of target product increases with the increasing of reaction temperature, gas pressure and reaction time. In the mine gas-Pd(OAc)₂-CH₃COOH system, the yield of CH₃COOCH₃ increases with the increasing of addition of Pd(OAc)₂ which is redox catalyst for mine gas conversion. The yield of CH₃COOCH₃ will be greatly improved by composite additional oxidant which is obtained by equimolar mix of p-benzoquinone with NO₂.
