HYDROTHERMAL DEGRADATION

Pt on alumina and activated carbon also show high activity, whereas Pt supported on Si02-Al203 and Zr02 show moderate catalytic activity for H2 production. Lower activity has been observed for Pt supported on Ce02 and ZnO, mainly due to the deactivation caused by hydrothermal degradation of the supports. [Pg.217]

It was proved that the lignin degradation can follow the Arrhenius equation [6]. Therefore, for model 1 to be used to predict lignin hydrothermal degradation, it is necessary to further estimate the pre-exponential factor ( o) and the activation energy E in the Arrhenius equation... [Pg.493]

The interphase has a significant effect on the mechanical properties and the failure mode of FRP composites (Benzarti et al, 2001). It may also affect long-term behaviour by controlling resistance to hydrothermal degradations. [Pg.365]

Studies have been reported on the hydrothermal degradation of silane coupling agents on E-glass fibres and polyester resin polymerization containing such fibres using Fourier-transform infrared spectroscopy, and the data show that there is a remarkable resistance to desorption when a highly ordered siloxane interphase is achieved. [Pg.165]

The effect of water absorption on the viscoelastic properties of glass fibre reinforced polyester and polyvinyl ester composites has been investigated using DMA by Fraga et al [ 481. These workers contrasted the water absorption behaviour of the pure, unfilled polymers with composites at two temperatures (40°C and 80°C) and evaluated the relative degree of hydrothermal degradation that occurred. [Pg.224]
