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 ...

Continuous Synthesis of Nanominerals in Supercritical Water [PDF]
Chemistry – A European Journal, 2019 AbstractThe synthesis of minerals should play a crucial role in the development of new and advanced materials. Since 2016, a renewal of interest to enlarge the mineral synthesis towards industrial requirements has been observed, especially thanks to three main recent papers.

Catalytic biodiesel synthesis under supercritical conditions [PDF]
Mendeleev Communications, 2021 The constant increase in greenhouse gases in the environment is forcing people to look for different ways to reduce such pollution. One of these ways is the use of biodiesel for road transport. Conventional biodiesel production involves the catalytic triglyceride transesterification process.

Synthesis of Amides and Lactams in Supercritical Carbon Dioxide [PDF]
The Journal of Organic Chemistry, 2009 Supercritical carbon dioxide can be employed as an environmentally friendly alternative to conventional organic solvents for the synthesis of a variety of carboxylic amides. The addition of amines to ketenes generated in situ via the retro-ene reaction of alkynyl ethers provides amides in good yield, in many cases with ethylene or isobutylene as the ...

Fischer-Tropsch Synthesis in Supercritical Phase.
Journal of The Japan Petroleum Institute, 1995 Fischer-Tropsch synthesis in supercritical phase was developed and its reactional behavior and mass transfer phenomenon were analyzed by both experimental and simulation methods. The same reaction apparatus and catalysts were used for both gas-phase reaction and liquid-phase F-T reactions to correctly compare characteristic features of diffusion ...

Supercritical Fluid Synthesis of Magnetic Hexagonal Nanoplatelets of Magnetite
Journal of the American Chemical Society, 2010 A supercritical fluid technique was used to prepare hexagonal nanoplatelets of magnetite. Ferrocene was used as the Fe source, and sc-CO(2) acted as both a solvent and oxygen source in the process. Powder X-ray diffraction, transmission electron microscopy, X-ray photoelectron spectroscopy, and magnetic measurements were used to characterize the ...

Continuous supercritical hydrothermal synthesis of nanomaterials
, 2019 The synthesis of minerals has been pushed in the last decade by their insertion into new and advanced materials as mineral fillers in ceramic, polymer, paper, cosmetic, pharmaceutical, cements … [1]. Up to now, the main synthesis method was the conventional batch synthesis characterized by long reaction times (few hours).
