TLDR
In this article, the authors investigated the performance of high sulfur-content heavy oil at sub-critical, near-critical and supercritical water (SCW) conditions, and showed that a viscosity reduction from 2073 to 1758mPa was achieved with a slight removal of sulfur (mainly sulfur) and the generation of a small amount of light and non-condensable hydrocarbons in gas phase (C1−C4, isoalkanes and alkenes, H2S, CO2 and H2, etc.).About:
