ABSTRACT:
The present invention provides a process for the preparation of propylene from a hydrocarbon feed containing one or more C5and/or C6cycloalkanes, wherein the hydrocarbon feed containing one or more C5and/or C6cycloalkanes 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 wherein at least 50% w/w of the total amount of zeolite used is zeolite in the hydrogen form.
