- Abstract
The paper presents data on the synthesis of ruthenium catalysts based on the zeolites HBeta, HΥ, HMordenite and HZSM‑5 and their testing in the hydrogenation reaction of levulinic acid to gamma- valerolactone in an aqueous medium at a temperature of 100 oC and partial hydrogen pressure of 1 MPa. For the initial zeolites and synthesized catalysts, physicochemical study was carried out using low- temperature nitrogen physisorption, XPS, DRIFT spectroscopy using CD3CN as a probe molecule, and electron microscopy. The dependence of the activity of Ru/zeolite composites on the surface content of RuO2 was established
