ABSTRACT:
There is disclosed a method for the modification of a natural clinoptilolite by acid treatment using a mineral acid at a suitable temperature and for a suitable period of time, followed by calcination, to produce a modified clinoptilolite which may be used as a catalyst in a reaction for the preparation of or transformation of hydrocarbons, e.g. the cracking of hydrocarbon products. There is also disclosed a method of regenerating the deactivated modified catalyst after use by treatment in the presence of nitrous oxide.
