Experimental evaluation of manganese ores for chemical looping conversion of synthetic biomass volatiles in a 300 W reactor system

Two manganese ores with different iron content were investigated as oxygen carriers for chemical looping conversion of simulated biomass volatiles. The aim was to study the performance regards combustion and potential use chemical-looping gasification wood-based biomass. studied in a 300 W reactor system circulation between fluidized air fuel reactors. temperature 850–900 °C flow rates 0.6–3 Lmin−1. Mn ore higher showed significant release at 900 under inert conditions, well full CO, H2 methane low flow. other little poorer gases when compared similar flows. However, gas composition attained rather if overall conversion. Nonetheless, slightly syngas fraction CO ratio product stream obtained lower content. In all cases increased formation fines (attrition rate), particle size distribution, bulk density measured evaluate their mechanical properties during
