Bioethanol Production From Hydrolyzed Lignocellulosic After Detoxification Via Adsorption With Activated Carbon and Dried Air Stripping.

摘要: Bioethanol production has been presented as an alternative for supplying energy demand and minimizing greenhouse gases effects. However, due to abrasively conditions employed on the biomass during pretreatment hydrolysis processes, inhibitors fermentation phase such acetic acid others can be generated. Based this problem, aim of work was evaluate adsorption microporous activated carbon investigate stripping same component with dried air. For process, three concentrations (5, 10, 20%) were analyzed by kinetics isotherms (Langmuir Freundlich models). Pseudo-second order model showed fit better when compared Pseudo-first model.
