| Abstract: | Palladium catalysts supported on silica gel were prepared. The catalytic behaviour ofthe catalysts in the hydrogenation of methyl acrylate was investigated. Several factors influ-encing the activity of the catatysts were examined. The results showed that the catalystspossess a high catalytic bydrogenation activity and good reusability. |
