Resumen:
Wet proofed catalysts were prepared by successive immersion steps of
conventional 37% CuO/Al2O3 samples in a PTFE fibres
suspension. Conventional and hydrophobic catalysts were tested for the
oxidation of phenol solutions (5g/L), at 140ºC and 7 atm of O2 pressure,
in a trickle bed reactor. For the conventional catalyst, phenol conversion
decreased with reaction time. However, for the wet proofed catalysts, phenol
conversion levels remained almost constant with usage. The hydrophobic layer
improved catalyst stability and minimized the solubilization of Cu2+.
