Abstract
A process is disclosed for enhancing the production of light olefins using a catalyst with small pores. The catalyst comprises a molecular sieve having 10 membered rings with channels of limited length. The molecular sieve has a high silica to alumina ratio and has pores sized to limit production of aromatics in the cracking process.
