Abstract:
Gasification enables the conversion of solid biomass into syngas. “Syngas”, also called “biosyngas” or “synthesis gas” is a fuel which contains H2 and CO among other things. It presents advantages regarding homogeneity, fuel handling and energy density, and offers the opportunity to use promising energy conversion processes. Nowadays gasification is still not a competitive solution due to techno-economical considerations, especially concerning the presence of tar in the syngas. Tar production in current gasifiers is too high compared to the requirements of downstream processes. It makes an intermediary syngas cleaning system indispensable. Many partially satisfying systems already exist, based on tar removal or on tar cracking. EIFER has patented a tar cracking system, based on the circulation of the syngas in a molten salt reactor. Early experiments have given encouraging results. An important question still remains: which part of tar removal is due to thermal effect and which part is due to catalytic effect? Based on fundamental research, this paper describes relevant aspects of tar removal in molten salt in order to distinguish the share of thermal and catalytic effects in the process.
