Abstract
A Raney type copper catalyst was prepared from a layer of Cu-Al alloy produced along the boundary of a copper plate and aluminum plates by hot-rolling. The fine particle catalyst of.0.03-0.09 pm diameter with the specific surface area of 317 BET m2/m2 attained the rate of 10.0 mol/h·m2 for 2-propanol dehydrogenation at 300°C, whereas a cleaned copper plate catalyst gave only 0.5 mol/h·m2. The catalyst structure and activity were changed by sintering and oxidation-reduction pretreatments (Table 1), which was compared with the thermogravity change for the representative catalysts (Fig.4).
