Surface kinetics, effect upon hydrogen

Deuteration is the exchange of surface silanol hydrogen atoms for deuterium. This process has been used to study the surface and structural properties of silica and their variation upon modification. The isotopic exchange of H for D is highly favoured by the kinetic isotope effect, because the mass of the D atom is double that of the H atom. [Pg.68]

In this work, the effect of the activation temperature upon the kinetic behaviour of the catalyst has been studied The physicochemical characterization has been carried out by XPS and TPR, and the variation of the surface properties has been related to the observed hydrogenation and coke formation kinetics. [Pg.558]
