Patent

CA 2379980

A process for producing propylene from a catalytically cracked or thermally cracked naphtha stream is disclosed herein. The naphtha stream is contacted with a catalyst containing from 10 to 50 wt.% of a crystalline zeolite having an average pore diameter less than 0.7 nanometers at reaction conditions which include temperatures from 500 ~C to 650 ~C and a hydrocarbon partial pressure from 10 to 40 psia. A separate stream containing aromatics may be cofed with the naphtha stream.

L'invention concerne un procédé de production de propylène à partir d'un flux de naphta soumis à un craquage catalytique ou thermique. Ce flux de naphta est mis en contact avec un catalyseur renfermant entre 10 et 50 % en poids d'une zéolite cristalline présentant un diamètre de pore moyen inférieur à 0,7 nanomètres dans des conditions de réaction comprenant des températures allant de 500 ·C à 650 ·C et une pression partielle de l'hydrocarbure comprise entre 10 et 40 psia. Un flux séparé contenant des aromatiques peut également être alimenté conjointement avec le flux de naphta.
