Adsorptive Removal of Organic Acids and Furans from Hydrothermal Treatment Process of Biomass
Hydrothermal treatment of plant biomass using subcritical water is one of the pretreatment methods for producing valuable chemicals such as D-glucose for producing bio-alcohol. However, this treatment causes side reactions and produces by-products such as organic acids and furans which
may inhibit the production of alcohols in the following step. In this study, the adsorption process is applied to remove by-products from products solution. As adsorbents, Cellufine A-200, A-800, DIAION WA21J, and activated carbon were used. Among them, Cellufine A-200 selectively adsorbed
organic acids and activated carbon showed the best adsorption performance for furans. DIAION WA21J adsorbed both organic acids and furans.
