Modelling and experimental studies on pyrolysis of biomass particles

Multiscale molecular modeling can be an effective tool to aid the development of biomass conversion technology: A perspective

“…Isolated experimental investigation into pyrolysis reactions and kinetics is extremely difficult due to several factors, such as, fast reactions, short residence times, high temperatures and transport limitations. Additionally, due to lack of knowledge of the reaction chemistry, studies investigating transport effects assumed few pseudo and lumped reactions (with fitted kinetic parameters) for pyrolysis (Blasi, 1996;Di Blasi, 1996;Hagge and Bryden, 2002;Chaurasia, 2004a, 2004b;Chaurasia and Kulkarni, 2007;Zabaniotou and Damartzis, 2007;Sadhukhan et al, 2008;Sreekanth and Leckner, 2008;Sadhukhan et al, 2009;Dufour et al, 2011;Haseli et al, 2011aHaseli et al, , 2011bHaseli et al, , 2012aHaseli et al, , 2012bPeters, 2011;Anca-Couce and Zobel, 2012;Blondeau and Jeanmart, 2012;Lin et al, 2012;Okekunle et al, 2012;Sharma et al, 2014). The prediction capability of such models remains very limited.…”

Numerical study of the conversion time of single pyrolyzing biomass particles at high heating conditions

“…The latter assumption has been previously adapted in several pyrolysis modeling studies; e.g. [5,[13][14][15][16][17][18][19][20], and it has been revealed that the main characteristics of the phenomenon could be captured by employing proper values for the kinetic data and the heat of reactions. Given that in some other studies shrinkage of particle during devolatilization has been modeled, Bellais et al [21], and Hagge and Bryden [22] have reported negligible impact of this effect on the process parameters.…”

“…Hence, in order to verify the accuracy of the pyrolysis model both heat and mass transport parameters need to be validated against measured data; see also Ref. [12,13,[18][19][20]29,30].…”

Numerical and Experimental Investigation of Intra-Particle Heat Transfer and Tar Decomposition during Pyrolysis of Wood Biomass

“…Therefore, it is important to discuss the effect of intra-partcle heat transfer on pyrolysis. Although researchers have investigated the effect of heat transfer during biomass pyrolysis (5)(6)(7) , numerical and experimental information available about the effect of heating rate on intra-particle transport phenomena is insufficient.…”
