“…In contrast, after addition of NiSO 4 into the hydrothermal solution, strong peaks of magnesium hydroxide and stearate appear for SA+NiSO 4 treated sample. Moreover, small peaks around 5.6° and 23° also appear in this condition, which can be attributed to nickel stearate according to the previous study [12]. As the large amount of substance with low surface energy MEMA-2022 Journal of Physics: Conference Series 2355 (2022) 012066 IOP Publishing doi:10.1088/1742-6596/2355/1/012066 3 (magnesium/nickel stearates) is beneficial for good hydrophobicity, it can be therefore inferred from XRD results that SA+NiSO 4 treated sample may have better hydrophobicity that of SA treated sample.…”

Two kinds of hydrophobic coatings on ZE41A magnesium alloy are successfully synthesized using hydrothermal method. The surface morphologies, wettability and anti-corrosion properties of hydrophobic coatings are investigated by the method of scanning electron microscopy, X-ray diffraction and electrochemical corrosion tests. Results show that the sample treated in stearic acid ethanol solution with addition of NiSO4 exhibits a morphology possessing large numbers of fine flower-like micro/nano structures, which results in better hydrophobicity and better corrosion resistance.

“…The efficacy of aquathermolysis in altering the properties of crude oil varies significantly with the choice and type of used catalytic systems. − During in situ catalytic upgrading, a precursor to the catalyst is introduced directly into the oil reservoir to facilitate the in situ upgrading process. This precursor undergoes modifications under reservoir conditions, transforming into an active form of the injected catalysts. , The active phase typically formed depending on the metals used (such as transition based: Mo, Co, Ni, V, and Fe) and their compounds. These metals react with the oil sulfur to form metal sulfides. , There are two main types of catalyst precursors: oil-/water-soluble and dispersed. , Oil-/water-soluble catalyst precursors dissolve directly in the crude oil or water.…”

In this work, the catalytic performance of a synthesized dispersed Ni-based catalyst [amorphous catalytic system of Ni(NO 3 )(OH)] in the hydrothermal upgrading of high-sulfur Cuban extra-heavy oil at temperatures of 200 and 300 °C for a duration of 24 h was evaluated. The synthesized Ni-catalyst predominantly exhibits an amorphous structure, which is primarily attributed to nickel hydroxonitrate (Ni(OH)(NO 3 )), as verified through X-ray diffraction and thermogravimetric Fourier transform infrared analyses. The results show that the presence of the synthesized catalyst in the upgrading system improves the physical and chemical properties of the upgraded oil samples compared to non-catalytic aquathermolysis results. The application of the Ni-based catalyst resulted in a reduction of sulfur content by 9.0−17.4%, a decrease in viscosity by 11.4−11.7%, and a lowering of the heavy oil fraction by 6.8−8.3%. Additionally, there was an increment in the production of gases by 0.2−0.3% and an increase in the fraction of hydrocarbons with a carbon number of less than < C 20 by 5.4−8.2%. The best upgrading performance was observed during catalytic aquathermolysis at 300 °C. Overall, the findings underscore the synthesized Ni-based catalyst's potential to significantly enhance the in situ hydrothermal upgrading process of extra-heavy crude oil, offering a promising approach for the treatment of such challenging feedstocks.
