The 6th International Hydrogen Technologies Congress (IHTEC-2022), Çanakkale, Türkiye, 23 - 26 Ocak 2022
Although
the Aspen Plus process simulator is widely used to model biomass gasification
processes, to our best knowledge, no study has yet been reported for the cattle
manure downdraft gasification process. This study presents downdraft
gasification characteristics of the cattle manure by performing sensitivity
analysis in the Aspen Plus process simulator. Effects of gasifier
temperature (between 600-1000 °C) and steam/biomass ratio (between 0.5-2.0) on
syngas composition and syngas lower heating value (LHV) were discussed. Sensitivity
analysis results indicated the higher ratios of steam/biomass and gasifier
temperature of 750 °C are the optimum conditions to produce H2-rich syngas
(more than 50% on dry basis). On the other hand, high
gasification temperatures and low steam/biomass ratios should be preferred in
order to obtain syngas with high calorific value.
