摘要: Dual fluidized bed (DFB) gasification of biomass generates numerous species with large differences in size and boiling point. At the heavier (tar) end, produced range from benzene to coronene. In this work, a method for elucidating pathways tar evolution is applied previously presented measurements that satisfy carbon balance Chalmers 2–4-MW DFB gasifier. addition quantifying cold gas tar, yield information regarding amount C, O, H composition unknown condensable (UCS). The reaction were identified by means fitting model performed measurements. employed solver varies freely rate coefficients three global reactions (mimicking dissociation hydrogen steam) per modeled group, as well distribution within predefined scheme. mature (excluding primary tar) spectrum divided into phenols, furans, benzene, naphthalene, pyre...
