All economies need energy for growth, particularly emerging ones with continued demand
for fossil fuels that move them to unconventional energy sources such as heavy oil …

Supercritical water upgrading (SCWU) of heavy oils reduces sulfur content and decreases
average molecular weight, without rejecting carbon as coke products. Despite many years of …

Supercritical water desulfurization (SCWDS) has potential as a technique for removing sulfur
from feedstocks such as heavy oil and bitumen. However, a fundamental understanding of …

This paper is the second part of the vacuum residue (VR) cracking in supercritical water and
tracking the chemical behavior of water as the hydrogen donor, using supercritical …

The reaction kinetics of the pyrolysis of heavy oil in the presence of supercritical water
(SCW) and high pressure N2 were measured. At any reaction temperature applied, the …

Hydraulic fracturing is an important approach for stimulating the production of ultra-low-
permeability oil reservoirs; however, the low flowback efficiency of the fracturing fluid (FF) …

Unconventional oil resources (oil shale, oil sands, extra heavy oil, and natural bitumen) and
residues (atmospheric and vacuum residua) can exploit hot compressed water (HCW: T> …

A detailed reaction network is proposed for the pyrolysis and desulfurization of hexyl sulfide
in the presence or absence of both supercritical water (SCW) and hexadecane, but without …

The objective of this work is to study the flow dynamics and mixing of supercritical water and
a model hydrocarbon (n-decane), under fully miscible conditions, in a small scale cylindrical …

Mixing of partially miscible fluids plays an important role in many physical and chemical
processes. The modeling complexities lie in the tight coupling of the multiphase flow, heat …
