Resumen:
It has been demonstrated that using low-cost materials and a relatively simple process, complex
supports with a mixed inorganicorganic structure can be synthesized. These supports combine
hydrophilichydrophobic dual properties and are especially suited for preparing egg-shell supported
metal catalysts to be used in highly exothermal catalytic reactions or in systems of consecutive reactions
where diffusive problems decrease the selectivity. The synthesized supports have an extremely
thin active layer. They also proved to be more mechanically resistant than other commercial supports
thus being amenable for use in continuous processes with long packed beds. Pd catalysts supported over
the new composite materials were found to be highly active for the selective hydrogenation of styrene,
a representative compound of pyrolisis gasolines. They also displayed smaller diffusive constraints than
other Pd catalysts prepared from commercial supports.
