“…These compounds are characterized by lower molecular weights and viscosities compared to resins and asphaltenes. The use of catalysts in the real oil field indicates that the catalysts can substantially reduce viscosity and hence the catalytic aquathermolysis process can be used successfully for exploration of heavy crude oils [41][42][43][44][45][46][47][48][49][50][51][52][53][54][55]. However, the oil soluble and dispersed catalysts are slightly more active than the water-soluble catalyst.…”

“…In the industry, the catalytic activity is dependent on the surface area, acidity-basicity (Brønsted/Lewis), shape selectivity, pore properties, stability, and availability and preparation routes. These factors are equally important to the aquathermolysis process [40][41][42][43][44][45][46][47][48]. The catalysts are materials such as zeolites and some oxides [50][51][52][53][54][55].…”

It has been estimated that the Earth has nearly 1.688 trillion barrels of crude oil, which will last 53.3 years at current extraction rates. The organization of petroleum exporting countries (OPEC) group forecasted that the oil prices will not jump to triple-digit territory within a decade, but it can quickly increase as the political issue for reducing oil production appears. With the potential of serious shortage of conventional hydrocarbon resources, the heavy oil, one of unconventional hydrocarbon resources including oil sand and natural bitumen has attracted worldwide interest. The heavy oil contains heavy hydrocarbon compounds, commonly called as resins and asphaltenes, with long carbon chains more than sixty carbon atoms. The high content of heavier fraction corresponds with the high molecular weight, viscosity, and boiling point. Physicochemical properties of residues from vacuum distillation of conventional oil, referred to as vacuum residues (VR) were similar to those of heavy oil. For the development of heavy oil reserves, reducing the heavy oil viscosity is the most important. In this article, commercially employed aquathermolysis processes and their application to VR upgrading are discussed. VR contains transition metals such as Ni and V, but these metals should be eliminated in advance for further refining. Recent studies on demetallization technologies for VR are also reviewed.

“…Heavy oil, a type of unconventional hydrocarbon resources, is known as the major energy in the 21 st century. Its reserves accounts for 70% of the total quantity of petroleum in the world (Y Chen, Yang, & Wang, 2010) (EIA, 2013). Substantial amounts of these reserves belong to the heavy oil category.…”

Steam injection has become commercially available thermal enhanced oil recovery methods for recovering heavy crudes. Recently, there has been increase in research interest in in-situ catalytic upgrading. In this work, experimental investigations on the application of a new submicron dispersed trimetallic catalyst based on Ni-Co-Mo for enhanced recovery and upgrading of Omani heavy crude oil was conducted. The catalysis effect of the ultra-dispersed Ni-Co-Mo metals generated in-situ from water-in-oil emulsion was studied in the presence of sand packed bed as a porous medium in a steam simulation process. The results from the recovery tests showed a higher oil recovery (15% OOIP) in the presence of the catalyst than base steam injection case. Substantial improvement in quality of produced oil was observed as there was a tremendous reduction in oil's viscosity of about 25% with significant reduction in sulfur (26%), and increase in API gravity (10%). This enhancement of the quality of Produced liquids in terms of increase in API gravity, viscosity and sulfur reduction, is an indication of successful in situ upgrading of the oil. Analysis of solid and gaseous products recovered from the experimental runs conducted with the catalyst showed thermal expansion and viscosity reduction due to catalytic hydrocracking as the dominant mechanisms for oil recovery.

“…5 Oil-soluble catalysts have a great advantage compared to the other types of catalysts; they can spread in heavy oil deposits and effectively catalyze the aquathermolysis process. 6 At the moment, various oil-soluble derivatives of Fe, Co, Ni, Mo, and W were examined as catalysts. 5 Carboxylates and sulfonates are usually used as a lipophilic ligands.…”

Catalytic Aquathermolysis of Heavy Oil with Iron Tris(acetylacetonate): Changes of Heavy Oil Composition and in Situ Formation of Magnetic Nanoparticles

We investigated the influence of catalytic aquathermolysis on the composition changes of Ashal'cha heavy oil. The synergetic effect of organic solvent and an oil-soluble catalyst leads to deep conversion of resins into light components. Composition changes of resins and asphaltenes before and after aquathermolysis were investigated by proton nuclear magnetic resonance ( 1 H NMR), Fourier transform infrared spectroscopy (FTIR), matrix-assisted laser desorption/ionization mass spectrometry (MALDI MS), and elemental analysis. It was shown that iron(III) tris(acetylacetonate) forms magnetic nanoparticles (MNPs) during aquathermolysis of heavy oil without any addition of surfactants. Composition of MNPs was determined as a mixture of hematite, magnetite, and maghemite. It turns out that obtained MNPs possess superparamagnetic properties of single-domain nanoparticles.
