PROCESS FOR THE MODIFICATION OF A NATURAL ZEOLITE TO PRODUCE A MODIFIED ZEOLITE FOR USE IN A REACTION FOR THE TRANSFORMATION OF MODIFIED HYDROCARBONS, CLINOPTILOLITE AND ZEOLITE

摘要

There is disclosed a method for the modification of a natural zeolite such as clinoptilolite by treatment with a suitable alkali, followed by washing, and then treatment with a suitable mineral acid, followed by calcination, to produce a modified zeolite which may be used in a process for the oligomerisation of propene to produce hydrocarbon products.
