Abstract
A hydrocarbon feed injection method is provided in which concentric inlet conduits carry hydrocarbon liquid and steam. Small nozzles located on the outer steam-carrying conduit discharge steam in the direction of the inner wall of the transfer line reactor to protect the inner wall from carbonaceous deposits. The hydrocarbon feed nozzles are staged along a line parallel to the longitudinal axis of the transfer line.
