| Abstract: | We have attempted to rationalize the preparation of metal/activated carbon catalysts, taking into account the surface properties of the support. The texture and structure of two commercial carbons, NORIT SX-1 and CECA BGP and of a third one C2, obtained from almond shell, have been fully characterized. These data were used for choosing the optimum conditions for the active phase incorporation. In this way, a fairly good loading and dispersion of ∼- 1% Rh on the supports have been obtained by adsorption from solution, using acetone and 4:1 benzene-ethanol as the suspension media. Some general considerations about the preparation of metal/activated carbon catalysts are given. |
