Abstract: Vacuum residuum was upgraded in an ultrasonic reactor of our own design. We found that during sonication in the absence of a hydrogen donor, the viscosity of the vacuum residuum is reduced by 10.98%; without sonication but in the presence of tetralin, it is reduced by 30.9%; and with combined tetralin treatment and sonication, the viscosity is reduced by 39.27%. The synergistic effect of ultrasound and tetralin results in a product with more stable viscosity, higher percentage of light components, lower densit… Show more

“…Experiments #2 and #5 can be considered to investigate the effect of adding water in HCUP. The reason for adding water in #5, and also #3, #4, and #6, is that water is identified as a hydrogen donor in heavy oil upgrading processes . Some researchers have used water to produce water/oil emulsions before applying HCUP .…”

“…There are some substances which could be used as a hydrogen donor for HCUP. Water, sodium borohydride, tetralin, citric acid, ammonia, methanol, ethanol, formic acid, hydrazine, methane, pentane, naphtha, light crudes, and hydrogen are mentioned in the literature . Non‐organic substances would make an emulsion when added to the process as a hydrogen donor making oil heavier and more viscous.…”

“…In addition, some changes in fuel composition have been reported [30] after sonication in heavier oil fractions than diesel only at severe conditions (high temperature, long time and presence of specific promotors) not found in diesel storage conditions. Biocides are chemicals with a high disinfecting power.…”
