Zusammenfassung:	A supported palladium catalyst having a palladium content of from 0.001 to 2 wt %, in which palladium is present, substantially in the absence of promotor metal, in the form of a layer having a thickness of less than 5000 nm forming a shell around the support, in which the palladium is applied in the form of a sol to a support by impregnation, or by spraying on to a heated support, and the use of said catalyst for the hydrogenation of acetylenes and dienes.
