Recebido em 23/1/09; aceito em 4/12/09; publicado na web em 8/4/10 Titania-supported Ir catalysts were used in the hydrogenation of furfural. Reactions were carried out in a stirred batch type reactor at 0.62MPa and 363K using a 0.10M solution of furfural in a 1:1 mixture n-heptane -ethanol as solvent. Catalysts containing 2 wt% of Ir were reduced in H 2 flow at different temperatures in the range 473-773K. The catalysts were characterized by H 2 chemisorption, TEM, TPR, TPD of NH 3 and XPS. Conversion of furfural is higher at lower reduction temperatures, but leads to byproducts whereas reduction at higher temperatures shows selectivity to furfuryl alcohol close to 100%.
