Gasification processes for polygeneration and including biochar and classification model
Gas Extraction and Gas Cleaning from a Novel Biomass Conversion Plant Based on Updraft Gasification
Short Introductive summary
The EU Horizon Europe project Clean bioenergy for industry (CBE4I) aims at the development of a novel, fuel-flexible biomass updraft gasification based technology for a highly energy efficient, almost zero emission and zero waste process heat supply for flexible implementation at industrial settings. Among others, this technology shall provide process heat and a clean product gas for utilisation in gas burners for direct heating. This paper focuses on the latter application. Approximately 40 wt% of the product gas derived from an air-blown, fixed-bed updraft gasifier is extracted directly from above the fuel bed, while the remaining portion is combusted in a multi-stage gas burner. To remove tars present in the extracted product gas, a combination of thermal tar reforming and high-temperature catalytic tar reforming using a novel catalyst is applied. The paper presents this newly developed technology and discusses results obtained from test runs performed at a 400 kW (fuel power based on NCV) testing plant.
