Iridium and palladium-iridium catalysts on carbon nanotubes were obtained by the hydrothermal method. The effect of the resulting catalysts on the yield and composition of birch wood hydrogenation products obtained in supercritical ethanol at 250 °C for 3 hours was studied. The influence of iridium and iridium-palladium catalysts in the process of hydrogenation of birch wood on the yield and composition of products has been established. The use of iridium-palladium catalysts in the process of hydrogenation of birch wood leads to an increase in its conversion by 40 wt. %, the yield of liquid products by 8 wt. %, while reducing the yield of solid products by 3 wt. % and gaseous products by 6 wt. %. In the presence of catalysts during the hydrogenation of birch wood, the yield of monomeric methoxyphenols increases to 47 wt. %
