Abstract:It is generally accepted that predictive models play crucial role in process optimization and continuous improvement in thermo-chemical conversion of biomass to fuels and chemicals. Several researchers have tried to develop a model that can predict the yield and composition of biomass fast pyrolysis . The predictive models developed so far are limited to lignocellulosic biomass such as pine and beech wood, where the ash content is limited to 5 wt%. To the best knowledge of the author, no model has been reported that can model waste paper sludge, where the ash content is significantly higher. The aim of this paper is to develop a kinetic model capable of predicting the yield and composition of waste paper fast pyrolysis. The model is based mainly on the multistep kinetics proposed by Ranzi et al. [1]. Intraparticle secondary cracking and experimental based catalytic minimodels are included to model other fast pyrolysis phenomenon. Compared with the experimental fast pyrolysis of waste paper sludge and other lignocellulosic biomass, the model seems to predict the yield and composition with an acceptable error margin. As a first attempt to model fast pyrolysis of waste paper sludge, this paper provides an innovative approach in extending the flexibility of kinetic models to handle a wide range of feed Keywords: Aspen plus, waste paper sludge fast pyrolysis, kinetic reactor model, Predictive model, Process modeling, fast pyrolysis oil refinery
