Gasification
Gasification aims to convert biomass into a gas which can be used in a fuel cell producing electricity.
In general, four gasification technologies can be differentiated: entrained flow, staged, fixed-bed and fluidised-bed gasification but there are also deviations between gasifiers from the same type. This project concentrates on six different gasifiers all over europe.
The gas mixture, produced in gasifiers, is called producer gas or syngas which comes from synthethis gas.
The gasification process operates at temperatures between 700 and 900°C by adding a controlled amount of oxygen and / or steam without any combustion. This leads to two output streams: producer gas and solid residues in form of vegetable coals and ashes.
Compared to combustion with gasification there is mainly carbon monoxide instead of carbon dioxide in the output. Other components are e.g. hydrogen, methane and steam. But also some components which hinder the further processing can be contained in this producer gas. The extraction of those are the crucial point of the research in the working package „gas treatment“.
