Abstract: This invention provides a nozzle for discharging a relatively small amount of a metals passivating agent into a catalytic cracking unit at a relatively high velocity through a relatively large diameter opening. This invention further provides a process for discharging a relatively small amount of a metals passivating agent into a high-temperature zone of a catalytic cracking unit, wherein the temperature range of the high-temperature zone exceeds the melting point of the particular passivating agent, through the utilization of a metals passivating agent injection nozzle which disperses the passivating agent, prior to discharging the agent into a catalytic cracking system, and accelerates this dispersed metals passivating agent to a maximum discharge velocity by injecting a dispersing agent into the novel nozzle at a location behind that at which the passivating agent is injected, and then discharging the dispersed metals passivating agent at a relatively high velocity through a passage having a relatively large inside diameter.
