“…This water contains a large number of phenolics, as shown in previous studies (Zhang et al 2012;Pham et al 2013). Thus, it is a source of environmental pollution and is difficult to dispose of (Yu et al 2002;Arana et al 2001). Most of the research has been focused on how to render it safe, rather than on its utilization as a resource.…”

-oil and hydrochar were produced through the hydrothermal liquefaction (HTL) of Salix psammophila (SP) branch residues with recycled processing water, in order to address the lack of water in deserts or sandy lands and the difficulty of water treatment in a batch reactor. The results indicated that the recycling of the HTL processing water could significantly improve the yield of bio-oil from 30.3% to 46.9%. The gas chromatography and mass spectrometry analyses of the obtained bio-oil confirmed the presence of value-added chemicals, such as phenolics, acetic acid, and furans. The acetic acid in the processing water played a key role in the HTL. The heavy oil had a high content (maximum of 42.7 wt%) of the low boiling point fraction (<300 °C), indicating its potential for further applications. The higher heating value of the hydrochar was about 27 MJ/kg, equivalent to the heating value of medium-rank and high-rank coals. These results show that HTL using recycled processing water has great potential for utilization of desert biomass wastes.

“…A variety of analytical methods has been used in their studies, such as size exclusion chromatography (SEC), 4 thermogravimetic analysis (TGA), 5 scanning electron microscopy (SEM)/energy dispersive X-ray analysis (EDX) 6 and FTIR. 7 Among these, FTIR is a kind of very useful analytical technique to monitor the degradation process, especially when ATR accessory is used. With it the changes in the molecular structures can be monitored continuously on one sample at the same position, giving plentiful information about the polymers investigated during their degradation.…”

Photochemical Degradation Study of Polyurethanes as Relic Protection Materials by FTIR‐ATR

et al. 2005

Polyurethanes are one kind of relic protection materials commonly used. During artificial photo-ageing, three polyurethanes, HDI-based polyurethane, MDI-based polyurethane and TDI-based polyurethane, have been considered to undergo UV radiation. Photochemical degradation of the polyurethanes has been monitored by means of Fourier transform infrared spectroscopy with attenuated total reflection accessory (FTIR-ATR). It was proved that the mechanism of the photochemical degradation of polyurethanes might be the scissions of carbamate (urethane) groups and the re-reactions of radical groups formed in the scission reactions. From the experiment results HDI-based polyurethane, an aliphatic diisocyanate, could be considered to be more suitably used as relic protection materials among these three polyurethanes for its ageing products with less color.
