Abstract

Improved Method of Feeding Slurry Catalysts to a Gas Phase Reactor A method of controlling the size of drops of liquid catalyst entering a gas phase polymerization reactor is taught herein to prevent the formation of large flaky particles which might result from the use poorly distributed polymerization catalysts suspended in a slurry, particularly mineral oil slurry. Said control is affected by using a either perpendicular spray nozzle or a perpendicular effervescent nozzle which produce finer catalyst slurry droplet dispersions, resulting in smaller individual droplets of contained catalyst and slurry solvent which results in fewer agglomerates and better overall catalyst utilization.
