Electrochemical degradation of per- and polyfluoroalkyl ...

1. Introduction. The global presence of per- and polyfluorinated substances (PFASs) in the environment is a topic of major concern due to their persistency, toxicity, and bio-accumulative potential (Niu et al., 2016; Ochoa-Herrera and Sierra-Alvarez, 2008; D. Zhang et al., 2016).The presence of multiple, highly stable carbon-fluorine bonds (bond dissociation energy up to …

Biorefinery and Bioethanol Production. Fossil resources are still primary energy and chemical sources; around 75% is used for heat and energy production, about 20% as fuel, and just a few percent for the production of chemicals and materials ().Natural regeneration of fossil resources through the carbon cycle is significantly slower than their current rate of exploitation.

Feb 22, 2022 Hydrogenations and hydrodeoxygenations represent two of the most important reactions in the production of both bulk and fine chemicals. Despite the wide and long use of metal-based catalysts for this reaction, there is still some uncertainty with respect to the properties governing the catalyst activity. Using the hydrogenation of benzaldehyde as a model reaction, …

Jan 11, 2021 Hydrothermal carbonization (HTC) is a thermochemical conversion process that uses heat to convert wet biomass feedstocks to hydrochar. HTC is performed in a reactor at temperatures ranging from 356 to 482F, i.e., 180 to 250C, under autogenous (automatically generated) pressure, with feedstock residence time ranging from 0.5 to 8 hours [1,2].

The power of such explosions was seen in the Chernobyl disaster, although the water involved did not come from fire-fighting at that time but the reactor's own water cooling system. A steam explosion occurred when the extreme overheating of the core caused water to flash into steam.
