Supercritical Synthesis of Biodiesel [PDF]
Molecules, 2012 The synthesis of biodiesel fuel from lipids (vegetable oils and animal fats) has gained in importance as a possible source of renewable non-fossil energy in an attempt to reduce our dependence on petroleum-based fuels. The catalytic processes commonly used for the production of biodiesel fuel present a series of limitations and drawbacks, among them ...

Modelling and experimental study of separators for co-solvent recovery in a supercritical extraction process [PDF]
, 2006 Co-solvent recovery in supercritical extraction is addressed here through a theoretical description of the behaviour of a CO2 + co-solvent mixture into a cascade of cyclonic separators, such as those existing in conventional fractionation processes based

Supercritical Water is not Hydrogen Bonded [PDF]
Angewandte Chemie, 2020 AbstractThinking about water is inextricably linked to hydrogen bonds, which are highly directional in character and determine the unique structure of water, in particular its tetrahedral H‐bond network. Here, we assess if this common connotation also holds for supercritical water.

The effect of synthesis conditions and process parameters on aerogel properties
Frontiers in Chemistry, 2023 Aerogels are remarkable nanoporous materials with unique properties such as low density, high porosity, high specific surface area, and interconnected pore networks. In addition, their ability to be synthesized from various precursors such as inorganics,

Nature of the Supercritical Mesophase
Natural Science, 2014 It has been reported that at temperatures above the critical there is no “continuity of liquid and gas”, as originally hypothesized by van der Waals [1]. Rather, both gas and liquid phases, with characteristic properties as such, extend to supercritical temperatures [2]-[4]. Each phase is bounded by the locus of a percolation transition, i.e.
