An Euler–Euler approach to modeling biomass fast pyrolysis in fluidized-bed reactors – Focusing on the gas phase

A numerical study on biomass fast pyrolysis process: A comparison between full lumped modeling and hybrid modeling combined with CFD

“…Therefore, many experimental studies have been conducted to determine the optimum conditions to obtain oil of higher yield and good quality (Bok et al, 2012(Bok et al, , 2013Choi et al, 2012;Ellens and Brown, 2012;Kim et al, 2014;Salehi et al, 2011;Wilson et al, 2013). For numerical studies, basic studies using computational fluid dynamics (hereinafter abbreviated as CFD) were carried out for the fast pyrolysis of biomass (Boateng and Mtui, 2012;Bruchmuller et al, 2012;Choi et al, 2009;Choi, 2011;Mellin et al, 2013;Papadikis et al, 2009a,b,c;Xiong et al, 2013aXiong et al, ,b, 2014Xue et al, 2011Xue et al, , 2012. Although lumped model study on mass analysis of fast pyrolysis is common, investigations on process analysis (using lumped model) is rare (Wright et al, 2010).…”

Co-production of pyrolysis oil and district cooling in biomass-based CHP plants: Utilizing sequential vapour condensation heat as driving force in an absorption cooling machine

“…A 10% change in the fluidization gas altered the condenser heat in condenser 1 by 4% and the amount of electrical power produced by 0.4%. Mellin et al [26] did an experimental investigation where they found out that the fluidization flow rate only had a moderate influence on the pyrolysis oil yield. The fluidization flow's moderate influence on the condenser heat and on the pyrolysis oil yield, combined with the lack of published material, were the main reasons for not pursuing any further investigation.…”

Detailed CFD modelling of fast pyrolysis of different biomass types in fluidized bed reactors

“…The use of computational fluid dynamics (CFD) coupled with a kinetic model to simulate fast pyrolysis of biomass is a convenient method . Much simulation work has been done to investigate fast pyrolysis of biomass.…”

“…In another simulation work of Xue et al, they compared the product yields of five different biomass types to investigate the relationships between biomass components and product yields . Mellin et al modelled biomass fast pyrolysis in different reaction atmospheres, and the composition of pyrolysis products were given and discussed in detail . Ranganathan and Gu simulated the fast pyrolysis of three different types of biomass, and the product yields were given and analyzed in their study …”
