“…To date, a great deal of progress has been made in upgrading heavy oils (such as oil sand [28,29], oil shale [30,31], Bitumen [26,32,33], residues [34], and heavy oil [35]) in SCW. To understand the current status of upgrading heavy oil in SCW, a timely sorting and summary of the progress made for the processes of heavy oil upgrading in SCW are necessary.…”

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.

“…A positive synergistic effect was reported on benzene-soluble oils. 16 Krasulina et al studied the co-liquefaction of Kukersite oil shale with pine bark in an autoclave at a fixed blend ratio of 1:1 (based on organic matter), and temperature range of 340−420 °C for 2 h with and without solvents (1.5 g/g water or benzene). 17 The use of either solvent (benzene) or water increased oil yields in every single feedstock, as well as in their blends.…”

The co-hydrothermal liquefaction of black pine wood (BPW) with Kukersite oil shale (KOS) at different blend ratios of BPW/KOS (1:1, 1:2, and 2:1) was conducted at 300 °C for 30 min. No synergistic effects on oil yields from the co-hydrothermal processing have been observed. However, when the methanol was substituted with hot compressed water as the solvent, positive synergistic effects on the oil yields were observed for all blend ratios, but the heating values of the oils from hydrothermal processing were higher than those from supercritical methanol processing under identical conditions. Co-hydrothermal liquefaction of BPW with KOS produced oils with less oxygen than those from co-supercritical methanol processing of BPW with KOS under identical conditions. The highest heating value from co-processing was 30.22 MJ/kg, which was obtained from the co-hydrothermal liquefaction of BPW with KOS at a blend ratio of 1:2. Oils from the co-hydrothermal liquefaction of BPW with KOS contained phenols, acids, ketones, and aldehydes. Guaiacol was the primary compound detected in the oils from co-hydrothermal processing. The relative yield of this compound was highest at a blend ratio of 1:2 (BPW/ KOS). The prominent compounds in oils from the co-supercritical methanol processing were esters and phenols.
