Chromic acid dealumination of zeolites [PDF]
Commercial zeolites with CHA, MFI, and LTL framework topology are subjected to acid treatment with chromic acid (H2CrO4) solutions with concentrations ranging between 0.1 and 10 w/%. As chromic acid forms polymeric species as a function of concentration, specific effects were obtained with these three zeolites, differing by their framework topology ...
