Upgrading of heavy oil using supercritical water (SCW) has attracted a lot of attention
recently due to the unique properties of SCW to act as hydrogen donor source and good …

The generation of hydrogen from unconventional oil is expected to increase significantly
during the next decade. It is commonly known that hydrogen is an environmentally friendly …

In this work, the effect of synthesized Ferrocene-based ligand catalysts, including Mono-, Di-
and Tri-Ferrocene, as additives for promoting the catalytic in-situ hydrothermal upgrading of …

Nowadays, with the increase in the rhythm of life, the relevance of using express diagnostics
methods for human health state estimation has significantly increased. We present a new …

Crude oils are extremely complex organic mixtures, composed of various constituents
ranging in size, shape and polarity. Obtaining a detailed insight into the petroleum …

The gas flooding has been well developed and been widely used for heavy oil recovery. The
extraction of light oil components by injecting gas with supercritical properties could destroy …

Model compounds were used to provide some chemical boundaries for the eight-fraction
SAR-ADTM characterization method for heavy oils. It was found that the Saturates fraction …

Application of high resolution 13 C nuclear magnetic resonance (NMR) spectroscopy to
characterize crude oil was demonstrated. The chemical shifts of 13 C NMR functional groups …

Forty-eight crude oils with variations in specific gravity (0.782≤ SG≤ 1.002), sulphur
content (0.03≤ S≤ 5.6 wt.%), saturate content (23.5≤ Sat.≤ 92.9 wt.%), asphaltene …

The present review focuses on the most recent advances in liquid‐phase NMR of
asphaltenes, leaving apart an overwhelming amount of publications dealing with solid‐state …
