The research results were published in《Water Research》 in 2020.Recommanded Product: 6-Aminonicotinamide The article conveys some information:
The critical challenge of hydrothermal liquefaction (HTL) for bio-oil production from biomass is the production of large amounts of aqueous products (HTL-AP) with high organic contents. The present study investigated the anaerobic digestion (AD) performances of HTL-AP under both thermophilic and mesophilic conditions, and mol. and metabolic anal. were conducted to provide insights into the different performances. The results showed that thermophilic AD had lower COD removal efficiency compared to mesophilic AD (45.0% vs. 61.6%). Liquid chromatog. coupled with organic carbon detection and organic nitrogen (LC-OCD-OND) anal. showed that both high mol. weight (HMW) and low mol. weight (LMW) compounds were degraded to some extent and more LMW acids (LMWA) and recalcitrant aromatic compounds were degraded in the mesophilic reactor, which was the main reason of higher COD removal efficiency. Ph compounds (e.g. phenol and 2 methoxyphenol), furans and pyrazines were the recalcitrant chems. detected through GC-MS anal. Fourier transform ion cyclone resonance mass spectrometry (FT-ICR-MS) anal. demonstrated the complexity of HTL-AP and the proportions of phenolic or condensed aromatic compounds increased especially in the thermophilic effluents. Metabolites anal. showed that the reasons contributing to the differences of mesophilic and thermophilic AD were not only related to the degradation of organic compounds (e.g. benzoate degradation via CoA ligation) in HTL-AP but also related to the microbial autogenesis (e.g. fatty acid biosynthesis) as well as the environmental information processing. In addition, the enrichment of Mesotoga, responsible for the high degradation efficiency of LMWA, and Pelolinea, involved in the degradation of Ph compounds, were found in mesophilic reactor, which was consistent with higher removal of corresponding organics To complete the study, the researchers used 6-Aminonicotinamide (cas: 329-89-5) .
6-Aminonicotinamide (cas:329-89-5)Recommanded Product: 6-Aminonicotinamide is a monocarboxylic acid amide resulting from the formal condensation of the carboxy group of 6-aminonicotinic acid with ammonia. An inhibitor of the NADP(+)-dependent enzyme,6-phosphogluconate dehydrogenase, it interferes with glycolysis.
