“…Thus, secondary asphaltenes are formed with a higher molecular weight. This trend has been reported for different crude oil samples and operating conditions. − The use of oil-soluble and water-soluble catalysts restrained this increase, where NiSO 4 and FeSO 4 catalysts presented the best capability to limit the aggregation of asphaltene (2979 and 3085, respectively).…”

Despite the remarkable effort performed to understand the reaction mechanism of asphaltenes during aquathermolysis reaction, the knowledge level about their molecular structures and reaction pathways is still limited. This work thoroughly reviews and discusses experimental results reported from different samples of asphaltenes during the aquathermolysis reaction to obtain information about the elemental composition, functional groups, and average structural parameters using analytical characterization techniques, including elemental analysis, Fourier transform infrared spectroscopy, synchronous fluorescence spectroscopy, X-ray diffraction analysis, electron paramagnetic resonance spectroscopy, and nuclear magnetic resonance spectroscopy. By studying the structural changes of asphaltenes, theoretical support is provided for future research on the aquathermolysis of heavy crude oils in the presence and absence of various catalysts such as water-soluble, ionic liquids-based, mineral, and heterogeneous. Characterization analyses show that the changes in asphaltenes are strongly influenced by the operating conditions, catalyst type, and asphaltene structure. Certain catalysts and hydrogen donors provide a higher effect on asphaltenes and their functional groups that have been observed through changes in the molecular weight, aromaticity, and condensation as well as representative parameters of the aggregation state of asphaltene molecules.

“…Wang et al 42 prepared a Ni−Mo/SiO 2 catalyst and evaluated the factors that affect the performance of the aquathermolysis of Liaohe heavy oil. It was observed that the viscosity decreases with the increase in temperature in the range of 180−280 °C, where the viscosity reduction rate at 240 °C has reached 81.19%, and the temperature rise has a slight influence on the viscosity reduction.…”

Steam-based technologies are promising procedures with great potential for the recovery of heavy oil reserves. Particularly, catalytic aquathermolysis has been identified as a relevant technology for the permanent upgrading of heavy crude oil to increase the recovery factor. This technology requires appropriate experimentation for evaluation of the effect of operational conditions on product yield and quality and catalyst performance, and to determine reaction kinetics and mechanisms. Consequently, the procedures used to generate, interpret, and analyze the experimental data required for optimizing the aquathermolysis process need to be properly defined and applied. This work reports an exhaustive review of experimental results reported in the literature on diverse upgraded oil samples. The effect of operating reaction parameters, such as temperature, oil/water ratio, time, and catalyst dosage, was discussed in detail. Based on experimental results, some behaviors in gas production and viscosity reduction are highlighted and explained for the development of future studies. It was concluded that the upgrading of crude oil is mainly influenced by the reactivity of the chemical compounds involved, and a detailed analysis of the reaction system is required for the experimental development and scale-up.

“…In addition, nickel-, cobalt-, and iron-based heterogeneous catalysts showed certain enhanced catalytic performance for aquathermolysis . Because of their low price and environmental friendliness, some nonprecious metals (especially iron-based catalysts) have more industrial application prospects. , Chen et al synthesized α-Fe 2 O 3 with an amphiphilic structure by mixing aromatic sulfonic acid with Fe 2 O 3 , which has high viscosity reduction performance for heavy oil.…”

Elucidating the structure–performance relationship of zeolites and their synergy with metals for the catalytic aquathermolysis of crude oil is crucial for designing efficient catalysts. Herein, the structure–performance relationship between the magnetic Fe-loaded zeolite’s physicochemical properties and aquathermolysis performance is mainly explored. First, the catalytic aquathermolysis performance of various porous materials (Y, β, MCM-41, and ZSM-5 zeolites) was probed to investigate the effect of different topological structures on the viscosity reduction of heavy oil. Results showed that ZSM-5 has a favorable pore structure and acidity, and its viscosity reduction performance is 1.7–4.1 times those of other zeolites; therefore, it is more suitable as a carrier for aquathermolysis to reduce viscosity. Then, Fe substance (such as Fe2O3 and Fe3O4) was loaded onto the ZSM-5 support. It was found that Fe3O4/ZSM-5 had better performance compared with pure ZSM-5 and Fe2O3/ZSM-5, which could reduce the viscosity of heavy oil by 20.3%. Importantly, the Fe3O4/ZSM-5 catalyst is easily separated from crude oil due to its magnetism, hence it has the potential to be recycled and reused. In addition, the potential structure–performance relationship was systematically studied by X-ray diffraction (XRD), elemental analysis (EL), transmission electron microscopy (TEM), and Fourier transform infrared spectroscopy (FT-IR). As a result, it was considered that Fe3O4/ZSM-5 broke C–S bonds and reduced the heavy components (resin and asphaltene) of crude oil. This study has a certain guiding significance for developing heterogeneous magnetic hydrothermal viscosity reduction catalysts.
