The possible use of supercritical fluid extraction (SFE) of coal to obtain cleaner, more versatile fluid products is of significant interest. Some fluids have the opportunity to participate as reactants at process conditions, which may yield extracts of very different compositions than those obtained from other treatments and which will be dependent on the fluid used. Thermodynamic consideratio...

In this paper the layout of pilot plant (100 kg/h) for the supercritical water gasification (SCWG) of biomass is proposed. The proposed layout involves a reactor, units to separate water and hydrogen, a burner and several heat exchangers. This scheme was also simulated by means of the commercial software Aspen Plus (Aspen Tech, Inc.) in order to state the influence of different parameters such ...

A high-performance liquid chromatographic method is developed for use in the electrospray mass spectrometric (MS)-MS analysis of alkaloids contained in Cephalotaxus harringtonia leaves. Nine alkaloids having ester groups can be separated and detected with good sensitivity. The MS and MS-MS spectra obtained provides information on their chemical structures. Supercritical fluid extraction is also...

A one-step synthesis of monoterpene alcohols such as lavandulol, linalool and geraniol/nerol from hemiterpene alcohols proceeds efficiently in supercritical water (scH2O) without any catalyst. Our device of a microreaction (μ-reaction) system achieves the production of lavandulol in 82% selectivity and 59% yield, respectively, even at a short reaction time of 7.7 s at 30 MPa and 375 in the near...
