Project 1, Acid-base & redox properties of promoted sulfated zirconia
Abstract:
During the calcination procedure that is necessary to obtain sulfated zirconia catalysts from hydroxide precursors an exothermic reaction occurs in the heat-up period which can lead to a rapid overheating ('glow') of the sample bed; the batch size is identified as a critical parameter that influences heat transfer and thus the extent of the temperature overshoot and the catalytic activity of the product.
