| 520 | _ | _ | |a The EU project GICO ("Gasification Integrated with CO2 capture and conversion", Grant Agreement No 101006656) focuses on the development of small to medium scale residual biomass plants based on sorption enhanced gasification. The use of CaO sorbents in a low-temperature-fluidised-bed-gasifier shifts the thermodynamic equilibrium towards higher H2 concentrations (from approximately 40% H2 to 75% H2) which is beneficial for the operation of a high temperature fuel cell. Simultaneously, a CO2-rich gas stream is produced by calcination of the resulting calcium carbonate allowing for carbon capture and utilisation.To remove harmful inorganic trace substances (sour gases and alkali compounds) from synthe-sis gases derived from residual biomass, suitable sorbents were first selected for the gasifier (650 °C) and the calciner (920 °C) based on literature and thermodynamic calculations. Several metals/metal oxides, aluminosilicates and alkaline earth compounds were considered. Equilibrium calculations with FactSage showed that aluminosilicates, Sr-, and Ba-based sorbents could reduce the alkali, respectively sour gas (H2S/SO2, HCl) concentration to sub ppmv levels. Condensation calculations revealed the need for temperature-resistant H2S sorbents since conventional ones, e.g. zinc oxide, tend to evaporate at the intended operation temperature, leading to the condensation of unwanted salts and oxides in colder parts of the plant. According to the calculations, unsaturated H2S/HCl sorption material from the gasifier such as BaCO3 and SrCO3 can be reused as SO2/ HCl sorbents on the calciner side.The sorption efficiency and capacity of aluminosilicates, alkaline earth, and rare earths-based sorbents was determined by mass spectrometry (MS) in fixed bed lab-scale investigations with simulated syngas. The investigations showed that aluminosilicates are suitable for alkali removal. Furthermore, the results indicate that Ca-stabilized Sr- and Ba-sorbents reduce H2S sufficiently. In both cases, concentrations could be brought below 1 ppmv.Based on both thermodynamic calculations as well as experimental results, hot gas cleaning concepts for the entire process are proposed. |
