Conversion of d-xylose into furfural with aluminum and hafnium pillared clays as catalyst

The industrial practice used to produce furfural is the dehydration of pentoses, which is carried out using highly corrosive and contaminating mineral acid catalysts. Because of the ecological and toxicological threats of this process and the complexity of product separation associated with these su...
