Flow Reaction

Catalytic production of CH3OH by direct oxidation of CH4 with O2 was performed using Cu zeolites in a CH4/O2/H2O flow reaction, where Cu-MOR exhibited relatively high CH3OH production with the redox of Cu(i)/Cu(ii) species.

Alternative Routes

AbstractThis paper analyses alternative routes for production of chemicals from different hydrocarbon gases by their direct, without syngas production, oxidative conversion to oxygenates or ethylene. Main of these routes are direct oxidation of methane to methanol (DMTM) and selective oxy-cracking of heavier natural or associated petroleum gas components which can be used for production of high value-added petrochemicals (in combination with carbonylation processes) and fuel gases, useful for gas piston engines. The advantages and practical capabilities of such technologies are discussed.

Base Properties

The surface redox and the weakly basic properties of FePO4 nanoparticles would contribute to the selective CH4 oxidation to HCHO and the suppression of over-oxidation, respectively.
