Pd/Ga2O3–Al2O3 catalysts for the selective liquid-phase hydrogenation of acetylene to ethylene
The structure of Ga 2 O 3 –Al 2 O 3 supports and Pd/Ga 2 O 3 –Al 2 O 3 catalysts and the performance of these catalysts in liquid-phase acetylene hydrogenation have been investigated. The deposition of Ga(NO 3 ) 3 onto Al 2 O 3 by impregnation followed by calcination of the impregnated support at 60...
