Abstract

Un método para tratar un reactor de lecho fluidizado de fase gaseosa y un método para polimerizar olefinas en un reactor de lecho fluidizado de fase gaseosa en presencia de un catalizador propenso a provocar laminacion, introduciendo un compuestocon contenido de cromo al reactor y formando un recubrimiento polimérico de alto peso molecular sobre las paredes del reactor. Más aun, un dispositivo y método para introducir el compuesto con contenido de cromo al reactor de lecho fluidizado en unapluralidad de lugares proximos a la seccion inferior de la pared de la seccion del lecho del reactor de lecho fluidizado, y formar un recubrimiento polimérico de alto peso molecular sobre la pared de la seccion del lecho.
