FZJ: Forschungszentrum Jülich GmbH - Institute of Energy Research, IEF-2 - Germany

Forschungszentrum Jülich, FZJ, is one of the leading research institutions in Germany with about 4400 employees. The research programme consists of 4 main research topics health, key competencies, earth and environment, energy, and structure of matter, which are worked at in an interdisciplinary way. Advanced power plants, fuel cells, renewable energies, fusion devices and fission reactors are the important fields of the main research topic energy technology.
The research field advanced power plants is carried out by the Institute of Energy Research (IEF-2). Major projects in this research field focus on the development of plants with combined cycle technology and with steam technology with supercritical steam parameters. The work is carried out in close cooperation with industrial partners to bring the technology developed into the market. For about 10 years, hot gas chemistry is a main topic at IEF-2. Within several national funded projects, the release of trace elements, hot gas chemistry, chemical hot gas cleaning, high temperature corrosion and slagging and fouling in coal based conversion systems has been investigated. By way of example, alkali sorbents for different processes have been developed within these projects. IEF-2 coordinated the FP5-project "HIAL" (ENK5-CT2001-00517) on combustion of annual biomass with high alkali content. Technical aim of the project was the development of primary measures for achieving low SO2 emissions. In FP7, IEF-2 is partner in the CHRISGAS project (SES6-CT-2004-502587) on biomass gasification. IEF-2 is responsible for analysis of detrimental trace elements and development of primary measures for reduction of these elements.
Major method for the gas phase analysis is high pressure mass spectrometry, HPMS. The mass spectrometric equipment established at IEF-2 is unique in Europe. The two high pressure mass spectrometer systems enable a complete on-line analysis of the hot gas with emphasis on inorganics. The sampling via a molecular beam allows the real time analysis of condensable and non-condensable, stable and metastable gaseous species. High temperature flue gases (up to 1700 °C, 15 bar) can be analysed with a detection sensitivity of < 10 ppb. Different lab-scale reactors coupled with the mass spectrometers will be used in the experiments. In addition to the HPMS systems SEM, XRD (also high temperature XRD if needed) and STA are available for the characterisation of the condensed phase. Chemical analysis will be made using the full spectrum of analytical methods in the Central Analytical Laboratory of Forschungszentrum Jülich. FactSage and SimuSage will be used for thermodynamic calculations. Several data basis (e.g. Fact, SGTE) are available.
