ABSTRACT:
Ammonia exchanged large port mordenite, which is subsequently mildly acid leached, and calcined, in which at least 95% of the exchangeable sodium has been removed and having from 0.38 to 0.8 milliequivalents of acid sites at least as strong as 48% sulfuric acid per gram (as measured by titration with butylamine, and employing dicinnamalacetone indicator) has been found to be highly active hydrocarbon isomerization catalyst. Incorporation of noble metal, e.g. palladium, on the catalyst improves the selectivity for isomerization of normal pentane to isopentane for highly active catalysts at high conversion rates.
