ABSTRACT:
A dehydrogenation process using an improved noble metal containing catalyst is disclosed. The catalyst comprises a non-acidic molecular sieve having a three-dimensional microporous framework structure of tin, aluminum and silicon tetrahedral oxide units. The non-acidic molecular sieve has a noble metal such as platinum dispersed thereon. The molecular sieve is rendered non-acidic by treating it with an alkali or alkaline earth metal. At least 10% of the tin is in a reduced oxidation state.
