Pretreatment of rice straw using microwave assisted FeCl3-H3PO4 system for ethanol and oligosaccharides generation

In this study, Box–Behnken design Response Surface Methodology (BBD-RSM) was used to develop microwave-assisted pretreatment (MAP) for Rice Straw (RS) using FeCl3-H3PO4 system. The concentration of FeCl3 and H3PO4, pretreatment temperature and time was used as independent variables and complex severity considering the effect of all variables were also calculated. Based on BBD-RSM, 57.5% of sugar yield per biomass was obtained for pretreated...
