The addition of surfactants and nanoparticles in minimizing wax deposition related problems such as flow assurance is considered an attractive alternative among other techniques but limited researches have been carried out in investigating the…
Background Heavy and super-heavy oils are characterized by a high content of resins and asphaltenes, which complicate the transportation and refining of oil and lead to an increase in the cost of refinery products. Currently, of particular interest…
Rational construction of multidimensional composites with abundant heterointerfaces is still a persistent challenge, especially dual interface structure. Herein, a facile interface engineering strategy has been put forward to construct…
Experiments were conducted simulating the hydrothermal effect on heavy oil in the presence of carbonate, kaolin, Al2O3, Ni+2 and Cu+2, NiO mixed with poly--olefins, C6H8O7, C2H4O2 at temperatures of 290-375C and pressures from 1,0 to 13.5 MPa. As a…
Alumina-supported Ni-promoted W oxides, carbides and nitrides were presulfided and employed for reducing pollutants and increasing the quality of an extra-heavy crude oil during catalytic upgrading reactions. These materials were prepared by…
Wax deposition can cause a slowdown in operation by restricting crude oil flow in the pipeline. Chemical inhibitors interact with the wax molecule in crude oil and prevent wax aggregation. The molecular dynamics (MD) simulation was used to analyze…
In this work the influence of catalysts on in situ combustion process of heavy crude oil has been studied. The heavy crude oil from Russia (Ashal'cha field) oil field was used. The research on oxidation was performed using accelerating rate…
The use of NiO nanoparticles as asphaltene co-precipitant additives is studied to improve the upgraded oil's properties and potentially reduce the solvent-to-oil ratio for the in-situ upgrading of heavy oils via solvent deasphalting. Asphaltene…
