摘要：

The dealumination of a NH4NaY zeolite through hydrothermal treatment at 500 ° C and 650 ° C occurs apparently through a kinetic law of the second order with respect to aluminium. The kinetic order is actually equal to one when the hydrolyzable aluminium atoms only are taken into account i.e. those to which ammonium ions and not sodium ions are associated. © 1990 J.C.
