Abstract

The aim of this work was to study the one-pot synthesis of sorbitol via hydrolysis-hydrogenation of cellulose in the presence of Ru-containing composites based on H<inf>3</inf>PW<inf>12</inf>O<inf>40</inf> supported on ZrO<inf>2</inf> and Nb<inf>2</inf>O<inf>5</inf> (Ru-PW/ZrO<inf>2</inf> and Ru-PW/Nb<inf>2</inf>O<inf>5</inf>). The main parameters impacted the reaction rate and yield of sorbitol, i.e. reaction conditions and type of catalyst were investigated. Ru-PW/ZrO<inf>2</inf> systems were more active than Ru-PW/Nb<inf>2</inf>O<inf>5</inf>. The yield of sorbitol was found to depend on the activation temperature of PW/ZrO<inf>2</inf> and PW/Nb<inf>2</inf>O<inf>5</inf> which affected textural properties, the amount of acid sites and size of Ru nanoparticles. The highest 66% sorbitol yield was observed in the presence of 3%Ru-PW/ZrO<inf>2</inf> activated at 550 °C and 1/1 of weight ratio of cellulose/catalyst, 180 °C, 7 MPa hydrogen pressure. This catalyst was stable for three cycles of the reaction without lost of it's activity.
