A process for the production of an olefin comprising partially combusting in a reaction zone a mixture of a hydrocarbon and an oxygen-containing gas in the presence of a catalyst which is capable of supporting combustion beyond the fuel rich limit of flammability to produce the olefin, wherein the superficial feed velocity of said mixture is at least 250 cm s-1 at standard temperature and operating pressure with the proviso that where the catalyst is an unsupported catalyst, the superficial feed velocity of said mixture is at least 300 cm s-1 at standard temperature and operating pressure.

L'invention concerne un procédé permettant de produire une oléfine. Ce procédé consiste à brûler partiellement, dans une zone de réaction, un mélange comprenant un hydrocarbure et un gaz contenant de l'oxygène, en présence d'un catalyseur capable de supporter la combustion au delà de la limite d'inflammabilité du mélange riche en combustible, afin de produire une oléfine. La vitesse d'alimentation superficielle de ce mélange est d'au moins 250cm s?-1¿, à une température et à une pression effectives normales, et si le catalyseur est un catalyseur non supporté, la vitesse d'alimentation superficielle du mélange est d'au moins 300 cm s?-1¿ à une température et à une pression effectives normales.
