CA 2650552

The present invention provides a process for the preparation of propylene from a hydrocarbon feed containing one or more C5 and/or C6 cycloalkanes, wherein the hydrocarbon feed containing one or more C5 and /or C6 cycloalkanes is contacted under cracking conditions with a one-dimensional zeolite having 10-membered ring channels and a silica to alumina ratio in the range from 1 to 500. The invention further provides an industrial set-up for such a process.

La présente invention a trait à un procédé permettant de préparer du propylène à partir d'une charge d'hydrocarbures contenant un ou plusieurs cycloalcanes C5 et/ou C6, qui consiste à mettre, dans des conditions de craquage, ladite charge d'hydrocarbures contenant un ou plusieurs cycloalcanes C5 et/ou C6 en contact avec une zéolite unidimensionnelle possédant des canaux à cycle à 10 chaînons et un rapport silice-alumine compris entre 1 et 500. L'invention concerne également une installation industrielle permettant de mettre en oeuvre un tel procédé.
