REPORT SUMMARISING THE LITERATURE REVIEW for Selection of Representative Syngas Compositions including Organic and Inorganic Contaminants

Within the BLAZE project, an SOFC from SOLIDpower will be integrated with a bubbled fluidised bed steam gasifier developed by UNIVAQ, USGM and WALTER TOSTO. This report has been made in order to understand if there are potential risks if the producer gas is fed to the SOFC. After an introduction in chapter 2, the current level of understanding what will be the gas quality, considering both relatively clean biomass feedstock (e.g. almond shells) and relatively dirty biodegradable waste (e.g. municipal solid waste) are considered and will be given in chapter 3. Then, chapter 4 summarises in a broad sense what is known about the operation of SOFCs with carbonaceous gases as well as the impact of contaminants that might exist in bio-syngas arriving from a BFB steam gasifier. Chapter 5 concludes with giving recommendations about the experiments that need to be carried out in work package 3 in order to successfully demonstrate the integrated system in WP 6. This deliverable is related to milestone MS3 “Selection of the test conditions for the experimental work” The indicators of success are the identification of at least 5 experimental and 5 simulative international peer reviewed papers on gasifiers/hot gas conditioning systems in order to select at least 2 representative compositions and 2 organic and 3 inorganic representative contaminants levels. This report identified 83 papers (mostly experimental) instead of 10, and 1 representative composition (owing to the decision to focus only on the steam gasification tested at pilot scale) and 2 organic (toluene and naphthalene) and 3 inorganic (H2S, KCl; HCl) representative contaminants levels.
