C-21: Novel Hydrogen Storage Reaction Pathway of LiBH4+MgH2 Mixtures Enabled by Ball Milling and Aerosol Spraying: Zhao Ding1; Leon L. Shaw1; Jie Li1; 1Illinois Institute of Technology
We have proved previously, that reaction between LiBH4 and MgH2 can indeed occur during ball milling with aerosol spraying at room temperature. In this study, the nanoscale MgH2 + LiBH4 mixtures are obtained by ball milling with aerosol spraying under ice-water cooling system (0℃). The amount of H2 released in the solid state from 25 to 265℃ reaches 3.88 wt.%, which is substantially higher than 0.75 wt.% and 0.1 wt.% H2 released by bulk LiBH4 and MgH2, respectively. Hydrogen uptake, although slower than release, can also reach 3.78 wt.% in solid state. All of these enhancements are achieved without any catalysts, which underscores the effectiveness of nanoengineering and mechanical activation as well as the opportunity for future improvements in the future.
C-22: Pyrolysis of Different Wood Species Investigated by TGA-GC-MS: Ekkehard Post1; 1NETZSCH Geraetebau GmbH
Wood is an important energy source with a zero carbon dioxide balance. This means the carbon dioxide produced during combustion was originally captured by the plants. Instead of firing the wood in air, it could also be heated up in inert gas atmosphere to produce charcoal and also gaseous organic products. The pyrolysis of different wood species was investigated by a thermo balance connected to a gas chromatograph with mass spectrometer (TGA-GC-MS). This instrument combination allows measuring the mass change of the substances versus temperature and time. By GC-MS the gaseous products were identified in real time (quasi-continuous), giving a direct correlation to actual temperature, time and mass. Alternatively, the gaseous products were collected in a “cryo-trap” at -50°C and analyzed after the TGA measurement by high resolution GC-MS analysis.The TGA-GC-MS results will be shown and explained for selected wood samples.
