英文摘要	pd-siw12/sio2 catalysts were investigated to elucidate the effect of preparation procedure on the direct oxidation of ethylene to acetic acid. pd-siw12/sio2 catalysts with a fixed amount of pd and siw12 were prepared in various ways. the order in which pd and siw12 were loaded on the sio2 support and the treatment conditions for the supported pd have a significant influence on the dispersion of pd on the pd-siw12/sio2 catalysts, but no influence on the concentration of b acid sites. the pd-siw12/sio2 catalyst prepared by simultaneously loading pd and siw12 on the sio2 support showed the best catalytic activity. the dispersion of pd was the main factor in the catalytic activity.
