ABSTRACT:
The invention is a solid catalyst having acid strength H.sub.o less than -18. Such catalysts are characterized by the ability to react with very weak bases, such as butane, at relatively low temperatures, for example temperatures in the range from 20.degree. to 200.degree. C. The catalysts have exceptionally high activity for various hydrocarbon conversion processes, for example, because of their exceptionally high acid strength.
