Abstract
A process and apparatus for heating catalyst is presented. Cooler catalyst is removed from a reactor and heated with a hot gas in a riser, heated in a heating tube or heated in a heating chamber. Heated catalyst is disengaged from the hot gas if necessary and returned to the reactor. The process and apparatus can be used for producing light olefins. The hot gas may be a flue gas from an FCC regenerator or a combustion gas from a heater.

A reactor apparatus comprising:
- a reactor vessel comprising a hydrocarbon feed inlet, a catalyst outlet in the reactor vessel, a product outlet in the reactor vessel and a catalyst inlet to the reactor vessel;
- a heating chamber in direct communication with the catalyst outlet and a source of gas;
- a riser in downstream communication with said catalyst outlet at a first end and said heating chamber in direct communication with a second end of said riser;
- said catalyst inlet in downstream communication with said second end of said riser.
