In this work, hydroxymatairesinol (extracted from Norway spruce knots) was hydrogenolyzed to matairesinol over palladium impregnated H-Beta-300, H-Beta-150, H-Beta-25, H-Beta-11, H-Y, H-Mordenite, H-MCM-41, H-ZSM-5, SiO ₂, and Al₂O₃. H-Beta-25 without palladium was also investigated. The hydrogenolysis was performed in 2-propanol at 70 °C under hydrogen and nitrogen atmospheres in a stirred glass reactor. The catalysts were characterized by nitrogen physisorption, direct current plasma atomic emission spectrometry, X-ray powder diffraction, CO pulse chemisorption, transmission electron microscopy, and Fourier transform infrared spectroscopy (pyridine adsorption). Palladium on H-Beta with different acidities was tested; the results showed that the reaction rate was inversely proportional to the acidity. However, Brønsted acid sites are needed for the reaction, because palladium on SiO₂ and Al₂O₃ is not active. In addition to the acidity, a metal is needed; the H-Beta-25 support without palladium displays no activity.
