Abstract

"FLUIDO DE FLUIDIFICAçãO". A invenção refere-se a um recipiente ativador de catalisador para condicionamento por calor de um catalisador. O recipiente ativador inclui recipientes interno e externo, uma placa de grade perfurada normalmente geralmente horizontal (16) dentro do recipiente interno, e uma trajetória de fluido que estende-se através da placa de grade dentro do recipiente. O recipiente interno pode ter um diâmetro interno de pelo menos 1,27m (50 polegadas). O espaço entre os recipientes interno e externo define uma tubulação. A placa de grade perfurada dentro do recipiente interno pode ter uma superfície superior perfurada com um perfil de depressões de sobreposição geralmente cónicas (54) e uma superfície inferior, opcionalmente de sobreposição por pelo menos 17%. A trajetória de fluido estende-se para cima através da placa de grelha perfurada e é um conduto ao longo do qual um fluido flui através da placa de grade. O fluido fluidificará um material particulado, tal como um catalisador, disposto acima da placa de grade no recipiente.
