In 2020,Energies (Basel, Switzerland) included an article by Shah, Ayaz A.; Toor, Saqib S.; Seehar, Tahir H.; Nielsen, Rasmus S.; Nielsen, Asbjoern H.; Pedersen, Thomas H.; Rosendahl, Lasse A.. Application of 826-36-8. The article was titled 《Bio-crude production through aqueous phase recycling of hydrothermal liquefaction of sewage sludge》. The information in the text is summarized as follows:
Hydrothermal liquefaction (HTL) is a promising technol. for the production of bio-crude. However, some unresolved issues still exist within HTL, which need to be resolved before its promotion on a com. scale. The management of the aqueous phase is one of the leading challenges related to HTL. In this study, the sewage sludge has been liquefied at 350°C with and without catalyst (K2CO3). Subsequently, aqueous phase recycling was applied to investigate the effect of recycling on bio-crude properties. Obtained results showed that the energy recovery in the form of bio-crude increased by 50% via aqueous phase recirculation, whereas nitrogen content in the bio-crude was approx. doubled after eight rounds of recycling. GCMS characterization of the aqueous phase indicated acetic acid as a major water-soluble compound, which employed as a catalyst (0.56 M), and resulted in a negligible increase in bio-crude yield. ICP-AES highlighted that the majority of the inorganics were transferred to the solid phase, while the higher accumulation of potassium and sodium was found in the aqueous phase via successive rounds of recycling. In addition to this study using Triacetonamine, there are many other studies that have used Triacetonamine(cas: 826-36-8Application of 826-36-8) was used in this study.
Triacetonamine(cas: 826-36-8) is a member of piperidine. Piperidine is ubiquitous structural motif widely occurred in diverse synthetically and naturally occurring bioactive molecules. Piperidines are an immensely important class of compounds medicinally: the piperidine ring is the most common heterocyclic subunit among FDA approved drugs.Application of 826-36-8
