Process and apparatus for distributing hydrocarbon feed and catalyst

摘要

A process and apparatus for fluid catalytic cracking feeds catalyst to a chamber of a riser. The catalyst exits the chamber and passes through a plenum and into a reaction zone through a plurality of tubes which distribute the catalyst uniformly over a cross section of the reaction zone of the riser. A hydrocarbon feed is fed to the plenum. The hydrocarbon feed passes from the plenum into the reaction zone through a plate comprising a multiplicity of openings which distribute the hydrocarbon feed uniformly over a cross section of the reaction zone of the riser. The feed is contacted with the catalyst in a reaction zone of the riser.

1. A process for fluid catalytic cracking comprising:
passing catalyst to a reaction zone of a riser through a plurality of tubes which distribute said catalyst uniformly over a cross section of said reaction zone of said riser through a plate; feeding hydrocarbon feed to the reaction of a riser through said plate; and contacting the feed with the catalyst in a reaction zone of the riser. said catalyst exits from said chamber through a tube.
