CA 2343272

This invention relates to a process for the production of olefins from a hydrocarbon, said process comprising the steps of: a) providing a first feed stream comprising a gaseous fuel and an oxygen-containing gas, b) contacting said first feed stream with a first catalyst under conditions so as to produce a product stream and unreacted oxygen, c) providing a second feed stream comprising a hydrocarbon feedstock, and d) contacting said second feed stream, said product stream of step b) and said unreacted oxygen of step b) with a second catalyst which is capable of supporting oxidation, thereby consuming at least a part of the unreacted oxygen to produce an olefin product.

L'invention porte sur un procédé de production d'oléfines à partir d'hydrocarbures comportant les étapes suivantes: (a) apport d'un premier courant d'un combustible gazeux et d'un gaz riche en oxygène; (b) mise en contact dudit premier courant avec un catalyseur dans des conditions donnant un courant de produit et de l'oxygène n'ayant pas réagi; (c) apport d'un deuxième courant constitué par une source d'hydrocarbure; et (d) mise en contact dudit deuxième courant avec le courant de produit de l'étape (b), avec l'oxygène n'ayant pas réagi, et avec un deuxième catalyseur pouvant supporter l'oxygène, ce qui consume au moins une partie de l'oxygène n'ayant pas réagi et donne une oléfine.
