Abstract:

The aim of this work is to find a new heterogeneous catalyst to convert the abundant methane gas in a direct route (one step) reaction into useful and transportable oxygenates using hydrogen peroxide as clean and efficient oxidation agent at mild conditions without using organic solvent. For this purpose, several catalysts have been selected and tested to oxidize methane to its oxygenates using hydrogen peroxide as oxidation agent. These catalysts were Al2O3, TiO2, TS-1, H-ZSM-5, Al-MCM-41, Ti- SBA-15 and Ti-MCM-41. Surprisingly, among all these catalysts, H-ZSM-5 (25) zeolite catalyst showed high activity and very good selectivity. Methane conversion over H-ZSM-5 (25) catalyst was much higher than over all other catalysts. About 85 mole% formic acid selectivity (based on methane conversion) and about 78 mole% (based on H2O2 conversion) at 21 mole% methane conversion were achieved over the self-synthesized HZSM-5 catalyst having SiO2/Al2O3=15 molar ratio. The by-product is only CO2. From catalyst performance testing and characterization results, it was concluded and proved that the Brönsted acid sites are the important and needed for this reaction.
