Modelling of biomass residence time distribution and xylan depolimerization kinetics analysis in a Pilot-Scale Pretreatment Continuous Tubular Reactor

摘要

An empirical mathematical model to describe the xylan depolymerisation in a pilot-scale pretreatment continuous tubular reactor(PCTR)is presented.The proposed model involves depolymerization kinetics and mass flow dynamics.Although the reactor was modelling as a set of reactors in series,typical impulse response delays,kinetic behaviours and disturbances in the initial concentration of xylans were successfully simulated with low computational cost.Tracer injection method and experimental runs using corn stover at different PCTR operational conditions were used for experimental validation.Additionally,the accuracy of the proposed model and the classic modelling method were compared.
