Investigation of Product Gas Quality During Absorption Enhanced Reforming of Different Biomass Fuels

N. Poboß, C. Hawthorne, M. Zieba & G. Scheffknecht
A gasification product gas with a H2 content over 75 vol-% and an heating value of 13 MJ/m³stp-dry basis has been obtained with the absorption enhanced reforming of biomass. The Absorption Enhanced Reforming (AER) process involves two coupled fluidised beds: a gasifier and a regenerator (calciner). The in-situ absorption of carbon dioxide by a sorbent (CaO) during steam gasification in the AER reactor provides the heat necessary for the endothermic gasification reactions. Due to the...
