摘要：

A new technique has been developed which can be used to determine the coverage-dependent heat of adsorption on supported catalysts from pulse experiments using a packed-bed adsorption column. This development is based on the theory of nonlinear wave propagation applied to a transient adsorption system. The unique feature of this technique is that the coverage-dependent heat of adsorption can be determined solely from the measurement of the column-average propagation speed of the adsorbate pulse, without any knowledge on the details of the pulse shape.
