The present invention relates to a method of producing methanol from a methane source by oxidizing methane under conditions sufficient to a mixture of methanol and formaldehyde while minimizing the formation of formic acid and carbon dioxide. The oxidation step is followed by treatment step in which formaldehyde is converted into methanol and formic acid which itself can further be converted into methanol via catalytic hydrogenation of intermediately formed methyl formate.

La présente invention concerne un procédé pour produire du méthanol à partir d'une source de méthane, par oxydation du méthane dans des conditions suffisantes pour obtenir un mélange de méthanol et de formaldéhyde, tout en minimisant la formation d'acide formique et de dioxyde de carbone. L'étape d'oxydation est suivie d'une étape de traitement au cours de laquelle le formaldéhyde est converti en méthanol et en acide formique qui peut lui-même être converti en méthanol par hydrogénation catalytique de formate de méthyle formé de façon intermédiaire.
