This paper describes the chemistry of green materials synthesized with supercritical fluids. First, the properties and some specific features of supercritical water are summarized. Then, supercritical hydrothermal synthesis of nanoparticles is explained, and various applications of green materials are described. The surface control of nanoparticles in supercritical water is also explained. Green processes involving chemical recycling of waste polymers and a combination of hydrothermal synthesis
The extraction of essential oil from peppermint leaves with supercritical carbon dioxide was studied in a semibatch-flow extraction apparatus. The extraction rates of the major components, l-menthol and menthone, were measured at various conditions: 313–353 K, 8.83–19.6 MPa. The exit concentration of l-menthol extracted from peppermint leaves was much smaller than the solubility of l-menthol. The extraction curves at various flow rates coincide in the plot of yield versus quantity of CO2 consume
Abstract BACKGROUND: Chlorella vulgaris is a green microalgae that contains various pigment components of carotenoids and chlorophylls. Supercritical CO 2 is widely used for extraction of pharmaceutical compounds because it is non‐oxic and easily separated from extracted material by simply depressurizing. In this work, pharmaceutical compounds from Chlorella vulgaris have been extracted using supercritical CO 2 with or without entrainer at various extraction conditions. RESULTS: Based on high pe
Supercritical water oxidation was applied to the destruction of municipal excess sewage sludge and alcohol distillery wastewater of molasses. The reaction was carried out in a batch reactor with hydrogen peroxide as an oxidant in the temperature range 673−773 K. Total organic carbon was measured as a function of reaction time. The dynamic data were analyzed by a first-order reaction model. The reaction rate constant coincides with those reported in the literature.
