Abstract
A paraffin having 5 to 10 carbon atoms is catalytically cracked in the presence of a catalytically cracking catalyst having a strong acidity, especially a rare earth metal ion-exchanged mordenite or a dealuminized mordenite, to form a paraffin having 3 or 4 carbon atoms. The formed paraffin is contacted with a dehydrogenation catalyst to obtain an olefin having 3 or 4 carbon atoms.
