Hydrogenation of Birch Wood in Supercritical Ethanol with Iridium and Palladium-Iridium Catalysts

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