摘要: During the calcination procedure that is necessary to obtain sulfated zirconia catalysts from hydroxide precursors an exothermic reaction occurs in heat-up period which can lead a rapid overheating (‘glow’) of sample bed; batch size identified as critical parameter influences heat transfer and thus extent temperature overshoot catalytic activity product.
