The kinetics of maltose hydrogenation using Ru-containing nanoparticles (NPs) formed in the pores of hypercrosslinked polystyrene (HPS) was studied in this work at 110-140 degrees C and 2-7 MPa. The concept of two sites and non-competitive adsorption of hydrogen and maltose was used due to large differences in the sizes of molecules. The proposed model was able to describe experimental data with sufficient accuracy. (C) 2015 Elsevier B.V. All rights reserved.
