 Abstract
In this study, we investigated kinetic model for the acid-catalyzed xylan hydrolysis at temperature . Also, we analyzed the kinetic parameters for xylose production and furfural decomposition. The hydrolysis of xylan and the degradation of xylose were promoted by high reaction temperature and acid concentration. The optimal hydrolysis condition for the highest reaction rate constants () was different depending on the acid catalysts. Among sulfuric, oxalic and maleic acid, the xylan reaction rate constants () to xylose had the highest value of when 100 mM sulfuric acid was used at . However, sulfuric acid induced more xylose degradation compared to oxalic and maleic acid hydrolysis. The activation energy for xylan degradation was the highest when sulfuric acid was used.
