“…This statement is also supported by the results of the SARA-analysis, where the content of resins and asphaltenes is the lowest in the presence of the SA-3 surfactant. The resins and asphaltenes are considered to be the most polar components of oil-dispersed systems [46]. However, the side chains of aromatic rings are generally unpolar molecules, and thus can be under the influence of surfactants.…”

The most widely applied methods to unlock heavy oil and natural bitumen resources in the world are still based on steam injection techniques. Improving the efficiency of hydrothermal processes poses a great challenge. The co-injection of various additives is practiced to lower the steam-to-oil ratio (SOR), viscosity alteration and to improve heavy oil properties. Organic solvents, non-condensable gases, air and surfactants are the preferred chemicals to be combined with steam. This study provides an investigation of the surfactant-assisted hydrothermal upgrading of heavy oil at 200 °C. The thermal stability and salt resistivity of two non-ionic surfactants (SA–3 and Biolub Green) were investigated. Moreover, the improved performance of the surfactants was established by performing an SARA analysis, elemental analysis, FT-IR spectroscopy, and EPR analysis, and by studying the viscosity reduction degree. The experimental results showed that surfactants lead to the in-depth destructive hydrogenation of the high-molecular components of heavy oil such as resins and asphaltenes. However, the content of light fractions increased. According to the results of the elemental analysis, the surfactants assist in the hydrodesulphurization of heavy oil. Overall, the physical and chemical consequences of hydrothermal upgrading in the presence of surfactants led to the irreversible viscosity reduction of heavy oil.

“…Currently, amorphous compounds play an ambiguous role in petrochemistry [4][5][6][7][8][9][10][11][14][15][16][17]19,[26][27][28][29][41][42][43][44][45][46][47][48][49]54,62,[66][67][68][69][70][71][72][73][74][75][76][77][78][79]. They are often considered as an undesirable component of heterogeneous alumina catalysts, since they are inevitably formed during the synthesis methods of aluminum hydroxides (precipitation and alcohol technology) [6,9,11,17,37,45,58,…”

“…In contrast to the conventional methods of processing heavy oils by thermal cracking and hydrocracking, the mechanisms of processing hydrocarbons with the presence of catalysts are more complex and still largely disputed in the scientific arena. For example, the alumina support plays an important role in the catalyst, which can also participate in the reactions at the catalyst active sites [67][68][69][70][71][72][73][74][75][76][77][78][79][80][81].…”

Aluminum oxides and hydroxides are widely applied because of the great variety of their modifications. In particular, aluminum oxides and hydroxides are used in petrochemistry and oil refining. However, amorphous aluminum compounds have not been sufficiently studied due to the complexity of their synthesis and the problems encountered during their study. The study of amorphous aluminum compounds is hindered by the ambiguity of terminology. In this work, the structures of amorphous aluminum compounds prepared by different methods and the properties that determine their applications have been highlighted in detail. Amorphous aluminum compounds play both positive and negative roles in petrochemistry; however, in petroleum refining, amorphous compounds (without promoters and transition metal salts) demonstrate a promising catalytic performance in oil upgrading.

“…However, all the operating system parameters must be considered to find the optimum concentration for the minimum coefficient of friction [39][40][41][42]. Numerous studies have been conducted to investigate the effect of TiO2 nanoparticles and MWCNTs on the tribological properties of base fluid, which in most cases improved the performance of the lubricants and oils [43][44][45][46][47][48][49][50].…”
