A method wherein a gas stream containing a methyl mercaptan is passed in contact with a catalyst comprising a supported metal oxide or a bulk metal oxide in the presence of an oxidizing agent and for a time sufficient to convert at least a portion of the methyl mercaptan to formaldehyde (CH2O) and sulfur dioxide (SO2).

L'invention concerne un procédé par lequel un flux de gaz contenant un méthylmercaptant est mis au contact d'un catalyseur, qui comprend un oxyde métallique de support ou un oxyde métallique en vrac, en présence d'un agent d'oxydation pendant la durée nécessaire à la conversion d'au moins une partie du méthylmercaptan en formaldéhyde (CH¿2?O) et en dioxyde de soufre (SO¿2?).
