Statistically Optimal Parameters of Aluminum Sulfate Catalyzed Hydrolysis for Furfural Production from Birch Inner Bark in the Framework of the Biorefinery Concept
Brazdausks, P., Rizikovs, J., Puke, M., Tupciauskas, R.
The aim of this study is to determine the optimal aluminum sulfate catalyzed hydrolysis parameters for furfural production from birch inner bark using a central composite design coupled with the response surface methodology. The conditions of hydrolysis such as temperature (165–175 °C), catalyst concentration (12–16 %), catalyst amount (6–8 %), steam flow rate (150–210 mL/min) and initial moisture content (20–26 %) of birch inner bark were varied according to the factorial design. Under the optimal conditions, the maximum furfural yield could be 54.6 % of the theoretically possible amount.
