Mass transfer limitations in binderless ZSM‐5 zeolite granules during adsorption of flavour compounds from aqueous streams

BACKGROUND Recently, a new process concept has been proposed to selectively adsorb wort off‐flavours, i.e. aldehydes, from alcohol‐free beers with hydrophobic zeolites. RESULTS In this work, we investigated the uptake of a mixture of wort flavour compounds (2‐methylpropanal, 2‐methylbutanal, 3‐methylbutanal, furfural, and methional), from a model solution onto binderless hydrophobic ZSM‐5 zeolite granules in order to quantify mass transfer...
