Studies on kinetic anal. and process modeling are important and necessary for the development of novel and efficient technol. for cellulose utilization. In this study, a kinetic model for the batch reactor was described for catalytic cellulose degradation in cooperative ionic liquid pairs based on an intensive anal. of the exptl. parameters. Our fitting results show that the proposed model agrees well with the exptl. data. The kinetic parameters obtained from the above model were subsequently applied to the continuous stirred tank reactor (CSTR) by constructing a math. process model for the continuous operation of cellulose degradation combined with product separation The effects of reaction temperature, retention time, extract flow rate and distribution coefficients were intensively investigated. The numerical results demonstrate that relatively high temperature and larger retention time are favorable in cellulose conversion, whereas the product distribution coefficient and extract flow rate mainly affect the concentration of the hexane-soluble fraction (volatile chems.).
