The article presents data on the use of heterogeneous catalytic systems in the process of fructose hydrogenation to polyols – sorbitol and mannitol, which are of great industrial importance. The results of kinetic testing of a ruthenium-containing catalyst synthesized using hyper-crosslinked polystyrene grade MN100 are presented. It was found that it is characterized by high activity in fructose hydrogenation, capable of carrying out the hydrogenation process with almost 100 % substrate conversion. The hydrogenation products were only sorbitol and mannitol, the yield of mannitol was slightly lower than sorbitol and amounted to 47 %. A comparison of the 5% Ru/MN100 catalyst with the commercial 5 % Ru/C in terms of fructose conversion and mannitol yield was carried out. It is shown that the catalyst used in the article exceeds 5 % Ru/C not only in activity, but also in mannitol yield.
