Abstract
Embodiments of the disclosure provide a method for producing light olefins from a hydrocarbon feed. The hydrocarbon feed and a water feed are introduced to a reactor to produce an effluent stream. The reactor is operated at a temperature and pressure such that cracking reactions occur in the reactor. The reactor includes a catalyst bed including a nanoscale zeolite catalyst having a crystal size ranging between 10 nm and 300 nm. The effluent stream includes the light olefins. The effluent stream is introduced to a first separator to produce a gas phase fraction and a liquid phase fraction. The gas phase fraction includes the light olefins. The liquid phase fraction is introduced to a second separator to produce a liquid hydrocarbon stream and a spent water stream.
