Abstract
DISPOSITIVO E PROCESSO PARA DISTRIBUIçãO DE CARGAS MISTAS SOBRE LEITOS FIXOS DE CATALISADOR EM REATORES DE FLUXO DESCENDENTE. A presente invenção trata de um dispositivo e respectivo processo para distribuição de cargas mistas que compreende uma bandeja plana em forma de disco, vazada por uma série de tubos coletores, localizada acima da superficie de leitos fixos de catalisadores, capaz de promover a homogeneização e distribuição de cargas através do dito dispositivo. Esses tubos coletores, montados desta forma, têm por objetivo restringir e reorientar o fluxo de cargas mistas, multiplicando os pontos de queda das mesmas, principalmente da fase liquida por sobre os leitos de catalisadores. Para fazer isto, esses dutos coletores, que são segmentos de tubos, que se distribuem por toda a superficie da bandeja possuem tampas, afixadas na extremidade superior dos mesmos, que impedem o fluxo direto da carga sobre o leito de catalisador e criam um reservatório de liquido sobre a bandeja, o qual é escoado posteriormente dispositivo abaixo de uma forma mais controlada.
