Incipient wetness 含浸
WebThe Pd catalysts used in HDO reaction were prepared by the incipient wetness impregnation of different supports with the aqueous solution of PdCl 2. To facilitate the comparsion, the Pd content in all catalysts are fixed as 5 wt%. The catalysts were reduced by H 2 flow (60 mL min-1 gcat-1) at 623 K for 2 h, cooled down in WebTsukuba
