ABSTRACT:
This invention provides for a process for hydrocarbon conversion in which a partially dehydrated hydrocarbon feedstock is contacted with at least two different molecular sieve materials, including a first molecular sieve having a Si/Al molar ratio of less than about 5 and a second molecular sieve having a Si/Al molar ratio of greater than about 5. Also, this invention includes such processes in which such feedstocks are contacted with a first molecular sieve having pores of at least about 6 Angstroms and a second molecular sieve having pores of less than about 6 Angstroms.
