Abstract

"APARELHO E PROCESSO PARA O CRAQUEAMENTO CATALìTICO FLUIDO EM REATOR DE FLUXO DESCENDENTE". é descrito um aparelho para craqueamento catalítico em fluxo descendente que compreende um 'riser' (10) de catalisador regenerado que carrega catalisador regenerado e um fluido carreador, esses sendo dirigidos através de uma seção transversal (20) para um distribuidor (30) que centrifuga gás e separa catalisador do fluido carreador, o catalisador sendo dirigido para um reator de fluxo descendente (50) através de uma cesta distribuidora (35) dotada de perfurações (32). A parte superior do reator (50) é provida de injetores de carga (41), que atomizam a carga de modo que a vaporização da carga e a mistura carga e catalisador são otimizadas. Após a reação de craqueamento no reator de fluxo descendente (50), os produtos de reação são separados e catalisador gasto é dirigido para as seções de retificação e regeneração. O processo de FCC efetuado no aparelho da invenção também é descrito.
