摘要：

A highly active catalyst for the decomposition of N(2)O was prepared by the thermal treatment of CoLaAl-hydrotalcite. For this catalyst the reaction rate was determined at various partial pressures of N(2)O, O(2) and H(2)O in a temperature range from 573 K to 823 K. The kinetic simulation resulted in a mechanistic model. The energies of activation and rate coefficients are estimated for the main steps of the reaction. (C) 1998 Elsevier Science B.V.
