Abstract

The synthesis procedure of activated carbons with basic properties is optimized in order to prepare abasic solid with a high number of strong basic active sites on the surface of the carbon material. The basicsolid is obtained from biomass waste (olive stone) and present appropriate porous structure for beingused as heterogeneous catalyst. The acid/basic properties of the surface of the carbons are studied bypH titrations. These carbon materials are used for the isomerization of lactose to lactulose, which findsmany applications in both pharmaceutical and food industries. This reaction is a route for revalorization ofwhey (which contains lactose). The results show that these carbon materials are quite promising for beingused as heterogeneous catalysts for this reaction, avoiding the use of corrosive homogeneous catalystsand revalorizing two different biomass wastes (olive stone and whey).
