Resumen:
The activity (TOF) and selectivity for methanol and methane syntheses from CO/H2 using Pd supported onto structurally different silicas (macro and microporous, DAVISON G-59 and G-03 types, resp.) has been evaluated. Reaction tests followed a careful follow-up of each of the preparation steps leading to the final catalysts. CH3OH is the main product on Pd/G-59 but with Pd/G-03 methane selectivity is much higher. In general the TOFCH3OH decreases smoothly, but TOFCH4 shows a marked descent, by increasing the exposed metal fraction (FE) of Pd.
