   Sammanfattning : The carbonaceous layer, formed on a Ni/SiO2 catalyst, and its influence on the selectivity in a hydrogenation reaction have been studied. The model reaction system studied was the consecutive hydrogenation of 2-ethyl-hexenal: Exposure of the catalyst to 2-ethyl-hexenal or cyclopentadiene at elevated temperatures before the hydrogenation, yielded an increased selectivity toward the formation of 2-ethyl-hexanal.
