Abstract

Patente de Invenção:<B>"TRANSPORTADOR AXIAL E REATOR DE CIRCUITO COMPLETO CONTENDO O DITO TRANSPORTADOR AXIAL"<D>. Um transportador axial é descrito, especificamente, para transportar dispersões de gás/líquido, no qual os elementos de transporte compreendem uma borda para varredura de parede, que aponta na direção do lado pressão dos elementos de transporte. O transportador axial é especialmente apropriado como um componente de circulação dentro dos reatores de circuito. Um processo compreendendo o transporte de dispersões de gás/líquido, bem como um processo para realizar reações químicas, diretamente, reagindo gás com gases não completamente dissolvidos em um meio líquido, ou, opcionalmente, na presença de sólidos finamente divididos, através do uso de um transportador axial, é também descoberto.
