Book Description
The characteristics and catalytic properties of solvothermal derived ZnAI [subscritp 2]O[subscript 4] supported palladium catalysts were investigated and compared in terms of catalytic activities for liquid-phase hydrogenation of 1-hetyne, 1-heptene selectivities and catalyst deactivation to those of solvothermal derived AI[subscript 2]O[subscript3] and ZnO supported Pd catalysts. It was found that the solvothermal derived ZnAI[subscript 2]O[subscript 3], ZnO formed single crystallite. The palladium catalysts supported on solvothermal derived ZnAI[subscript 2]O[subscript 4] and ZnAI[subscript 2]O[subscript 3] calcined at higher temperature exhibited better performances than those supported on the supports calcined at lower temperatures. Moreover, it was found that Pd catalyst support on solvothermal-derived alpha alumina exhibited the higher activity than those supported on commercial one. For catalyst deactivation, Pd catalysts on the supports calcined at high temperature showed lower amount of Pd leaching.
