“…The effects of reaction conditions on the extract yield and the extract constituent of SCW have been reported by many researchers [30,37,39,55]. As expected, increasing temperature would transform more asphaltenes and polarities into paraffins and aromatics, and increase the oil yield.…”

Abstract:With the growing demand for energy and the depletion of conventional crude oil, heavy oil in huge reserve has attracted extensive attention. However, heavy oil cannot be directly refined by existing processes unless they are upgraded due to its complex composition and high concentration of heteroatoms (N, S, Ni, V, etc.). Of the variety of techniques for heavy oil upgrading, supercritical water (SCW) is gaining popularity because of its excellent ability to convert heavy oil into valued, clean light oil by the suppression of coke formation and the removal of heteroatoms. Based on the current status of this research around the world, heavy oil upgrading in SCW is summarized from three aspects: Transformation of hydrocarbons, suppression of coke, and removal of heteroatoms. In this work, the challenge and future development of the orientation of upgrading heavy oil in SCW are pointed out.

“…The results showed that SCW extraction gave the highest oil yield, but this oil contained a high proportion of asphaltenes and polar compounds because of the extraction of SCW, and the reaction of SCW with the oil shale kerogens [39].…”

“…Turkish (Beypazari) oil shales were extracted with water at 623 (subcritical) to 698 K, with the asphaltene fraction diminishing but the polar fraction of the produced oil increasing in this temperature range [52]. Supercritical water applied to Moroccan oil shales at 653 K to 673 K yielded oils with increasing yields and diminishing fractions of asphaltenes [53]. Jordanian (El-Lajjun) oil shales were subjected to retorting and supercritical extraction with CO2 and with water.…”

Hot, subcritical and supercritical water, methanol, ethanol and their binary mixtures have been employed to treat fuels (desulfurize coal and recover liquid fuels from coal and oil shales) and to extract valuable solutes from biomass. The properties of these solvents that are relevant to their extraction abilities are presented. Various extraction methods: accelerated solvent extraction (ASE), pressurized liquid extraction (PLE), supercritical fluid extraction (SFE, but excluding supercritical carbon dioxide) with these solvents, including microwave-and ultrasound-assisted extraction, are dealt with. The extraction systems are extensively illustrated and discussed.
