Phenomenological modeling and evaluation of formic acid pretreatment of wheat straw with an extended combined severity factor for biomass fractionation and enzymatic saccharification to produce bioethanol

摘要: Abstract Chemical pretreatment of lignocellulosic biomass is a complex system involving heterogeneity and complicated reactions. Rigorous kinetic modeling this not possible, but phenomenological with parameter severity factor (SF) may provide useful information in wide operational range. In the present work, an extended combined ( CSF ext ) was defined by contribution solvent concentration for evaluating formic acid wheat straw order to achieve fractionation components improve cellulose digestibility bioethanol production. Two models based on classical Arrhenius modified Logistic equations were developed describe solubilization polymeric components. Although determined values somewhat different models, tendency component respect similar. With integrated consideration solubilization, formylation enzymatic glucan conversion, condition suggested be controlled at Arrhenius-based 23–24 or Logistic-based 25–26. thus can applied as temperature, time reaction process.
