Description: Das Projekt "Vergasung von Kohle geringer Qualitaet in der Wirbelschicht: Ein neuartiges Verfahren der gesetuerten Zufuhr von sauerstoffangereicherter Luft mittels Gastrennmembranen" wird vom Umweltbundesamt gefördert und von GKSS-Forschungszentrum Geesthacht, Standort Geesthacht, Institut für Chemie durchgeführt. The proposed project is focused on the development of new technology of processing of low quality, high ash coals, their mixtures, as well as organic wastes like timber in order to obtain improved energy parameters in gasification and combustion processes. An important feature of the proposed project is the use of lower temperature regimes of fluidized bed gasification, for which melting of ash components and, hence, diffusion limitations are prevented. However, in order to overcome a difficulty related to reduced reaction rate in this regime, controlled injection of oxygen into gasification unit is accomplished, what permits to intensify the process and decrease atmospheric discharge of solid particulate in flue gas. It is also relevant that oxygen enriched streams will be obtained via flexible membrane gas separation technique. Thus the proposal implies close collaboration of the specialists in fossil fuels gasification and membrane technology. This is the first attempt to apply membrane technology in this industrial area. The results of this research can be important for both NIS/CCE and EU countries, because reserves of lower quality coals are available in all these regions and will certainly be used in next century. The proposed R and D project can be divided into the following main research tasks, namely: 1. Experimental study of gasification process in the presence of oxygen enriched air and development of the model of gasification process in intensified regime. 2. Choice of membranes and membrane apparatuses for oxygen enrichment of air for coal gasification; selection of optimized regime of the joint work of membrane and gasification units. 3. Tests of the process on a demonstration (pilot plant) unit with development of recommendations for further practical application of the process for gasification of different types of feedstock (coals, lignites, solid wastes, mixed feedstocks). The interest from industry to this process is shown. The research tasks in this projects will be carried out by six different organizations, two from EU and four from Russian and Ukraine. Three in-profit institutes (from Germany, Italy, and Russian) and an industrial partner from Ukraine are involved; in addition, two non-profit institutes from Russian will take part in this project.
