Abstract
Procedimiento para separar productos gaseosos de catalizador regenerado caliente con un gas de chimenea, antes del paso a una operación de conversión de hidrocarburo, que comprende pasar el catalizador regenerado caliente, con gas de chimenea arrastrado que contiene CO2, descendentemente, como corriente confinada, a una zona que comunica un flujo de catalizador anular centrífugo a la corriente confinada que fluye descendentemente, alrededor de una zona situada centralmente cerrada en su extremo superior pero abierta en su extremo inferior, poner en contacto la corriente de catalizador anular que fluye con gas combustible, y desplazar CO2 del catalizador, retirar gas combustible con CO2 desplazado a la zona situada centralmente, para retirarlo de la operación de separación, y retirar catalizador regenerado del que se ha desplazado CO2, por debajo de la zona situada centradamente, para transferencia a una zona de conversión de hidrocarburo.
