The deactivation of a copper–zinc oxide catalyst has been studied in a set of parallel tests which covered a range of space-times with equal flow and variable catalyst quantity, from 1/8th bed to full bed. The activation–deactivation trends over

The unique feature of the zeolite catalysts is the presence of catalytically active acidic hydroxyls, also known as Bronsted acid sites (BAS), in the zeolite micropores of molecular dimensions. The accessibility and catalytic properties of BAS depend

The method of decreasing conversion, constant space−time (DCCST) is sometimes used for empirical determination of catalyst decay kinetics in fixed beds. The method of constant conversion, increasing space−time (CCIST) is used infrequently. Althou
