Item type:Publication, Access status: with files , Diskrete-Elemente-Modellierung der pyrolytischen Zersetzung und Fragmentierung von Holzpellets im Chemical-Looping Vergasungsprozess(2024); To enable a more accurate prediction of breakage and attrition for the chemical looping gasification of biomass, a numerical model for the behavior of devolatilized wood pellets was developed. Experimental investigations revealed the generation of a macro-porous structure during devolatilized. Under mechanical loads, this results in complex failure behavior. Based on these findings the bonded-particle model has been extended to predict the thermochemical conversion and the induced structural changes. Subsequent mechanical simulations show good agreement with the experiments and demonstrate the possibility of modeling the breakage of the pellets in a gasification reactor.Publicationtype: Doctoral Thesis43 335 - Some of the metrics are blocked by yourconsent settings
