A Comparison of Kinetic Modeling of Fermentable Sugar Production from Walnut Green Skin as a Source of Energy
The effect of process condition (acid concentration, solid content, temperature, and time) on fermentable sugar production by concentrated acid hydrolysis for green walnut skin pretreatment was studied. Dried WGS with solid to liquid ratio of 5%, 10%, 15% was treated with 20, 40, 60 wt% sulfuric acid at 65, 80,90°C for 2, 3, 4 hours and final solutions were analyzed by HPLC. The process was modeled by three models: first order reaction kinetics, using severity factor and a second order equation. The work indicates that the use of Walnut green skin may be a feasible option as a feed material for the production of glucose for biofuel synthesis.
