Production of Synthesis Gas from Biomass Residues by Staged Fixed-bed Gasification - Results from Pilot Test Campaigns

Fluidized-bed and entrained-flow gasification systems are developed for large-scale synthesis gas applications with at least 100 MW biomass input. However, there is also a market need for smaller-scale plants, which could be better integrated into energy production systems and local biomass logistic...
