    摘要: The present invention refers to a catalytic system comprising a platinum compound on a solid carrier, wherein the content of the platinum species on the surface of the solid carrier is from 0.1 to 15 wt.-%, based on the dry weight of the solid carrier. The solid carrier is a precipitated calcium carbonate (PCC) and has a specific surface area of from 15 to 100 m 2 /g measured using nitrogen and the BET method according to ISO 9277:2010; and the platinum compound is selected from the group consisting of elemental platinum, platinum oxides and mixtures thereof. Furthermore, the present invention refers to a method for manufacturing the catalytic system, the use of the inventive catalytic system in a chemical reaction, the use of a solid carrier loaded with a platinum compound as a catalyst and to granules mouldings or extrudates comprising the catalytic system.
