The role of the ‘glow phenomenon’ in the preparation of sulfated zirconia catalystsElectronic supplementary information (ESI) available: boats used for calcination. See http://www.rsc.org/suppdata/cc/b1/b100364j/

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.
