“…Currently, with the rapid development of the economy and the dramatic growth of population, the demand for fuel oil is decreasing while the demand for light oil is increasing [6,7]. Unfortunately, the reserves of conventional crude oil suitable for the production of light oil is scarce and insufficient to meet the ever-growing energy demand [8,9]. To reduce the energy gap, taking the heavy oils as an oil substitute, and converting them into light fractions, may be an alternative choice [2,3,10,11].…”

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.

“…Very limited number of studies, if any, have been conducted so far to address the leakage of the subsurface, thermogenic methane as a stray, and contaminant gas. Studies on reducing leakage of gases from a subsurface environment have been predominantly focused on CO2 449 leakage via carbon capture and storage (CCS) operations and enhanced oil recovery processes 450 [48][49][50][51][52][53]. Thus, research conducted on the reduction of CO2 leakage will be documented and used as a base to design a suitable experimental analysis addressing methane leakage.…”

Shale gas extraction is seen to be a bridge fuel to the future due to lower GHG emissions compared to oil. However, it is also one of the most controversial topics due to the involvement of fracking in their production. Based on the analysis performed in this review we found that despite hydraulic fracture propagation being a possible conduit of methane leakage, the major cause of gas leakage is through leaking wells within the vicinity of fracturing sites. Remedial attempts have revealed promising yet inconsistent results, with no concrete method established for the methane leakage mitigation from shale gas wells.

“…With the continuously growing demand for petroleum and decreasing reserve of regular crude oil, there has been much interest in the utilization − and upconversion of heavy oil (≥100 cP). − Current upgrading technologies are based on carbon rejection and hydrogen addition routes, which also contain limitations . The carbon rejection route has a relatively low recovery of liquid, along with the generation of a large amount of coke, while in the latter route, the expensive catalysts tend to deactivate easily.…”

Computational studies at the M06/6-311G(d,p) and M06-2X/6-311+G(d,p) levels were performed to explore the detailed mechanism of isoquinoline ring-opening and denitrogenation in a supercritical water system. Three reaction paths with the same product, 2-(2-oxoethyl) benzaldehyde, were supported by the computational results. The rate-limiting step in the major degradation reaction is an addition reaction at the N position. H2O is added to both the 1C–2N double bond (1C–2N addition reaction) and the 2N–3C double bond (2N–3C addition reaction) of the isoquinoline molecule, where the oxygen of H2O is added to the carbon atom. The energy barrier of the 1C–2N addition reaction is 52.7 kcal/mol, while that of 2N–3C addition (from Path 6) is 60.1 kcal/mol. From catalysis by two water molecules, the barrier of 1C–2N addition (Reaction (1)) is reduced to 27.5 kcal/mol. Catalysis from water molecule clusters is shown to considerably affect the process of isoquinoline ring-opening and denitrogenation, as indicated by comparing the reaction energy barrier heights with and without water catalysts.
