Hemicellulose hydrolysate upgrading was performed over BEA zeolites containing Si/Al equal to 12 and 19. A model hydrolysate was prepared considering typical concentrations of xylose, arabinose, furfural and acetic acid representative of hemicellulose hydrolysate from Brazilian sugarcane bagasse. BEA zeolite showed to be an effective catalyst to promote the hydrolysate upgrade into platform molecules. Acetic acid participated in the reaction as a homogeneous Brønsted co-catalyst but BEA zeolite plays a decisive role as it strongly affects products distribution. Pentoses with different molecular configurations produced different products due to hydroxyls steric positions. The presence of acetic acid did not damage the catalyst.
