Abstract

Un procedimento di rimozione di un catalizzatore, in particolare di nichel di Raney, da un prodotto di una reazione catalitica, in particolare un prodotto di una reazione di idrogenazione, facendo passare il prodotto della reazione catalitica contenente il catalizzatore solido attraverso un mezzo filtrante tubolare cavo che comprende una trama non tessuta di fibre, che ha una distribuzione dei pori conica tale che le dimensioni dei pori nel mezzo filtrante diminuiscono nella direzione del flusso normale del fluido, e che è controlavabile.
