“…Currently, catalytic systems based on nanoparticles are known as the most effective catalysts for oil combustion. Compounds of different transition metals, like Cu, Fe, Ni, Ti, Zr, Ce, and Pd, in the form of nanoparticles were tested in the combustion of heavy oils and high molecular components of them. − In particular, our studies showed high catalytic activity of Mn-based catalysts in the oil oxidation process. , Detailed investigation of the transformation of the active phase of the catalyst by X-ray powder diffraction and electron paramagnetic resonance techniques allowed us to reveal some mechanistic insights into catalytic oil oxidation . In general, catalysts based on platinum group metals and rare-earth elements possess superior catalytic activity toward organic matter oxidation; however, the high prices of these metals hinder their application for heavy oil production, and use of transition metals of the fourth period for that purpose looks more reasonable.…”

Nanoparticles have proven to be successful catalysts for oil combustion. To maximize their catalytic performance, it is necessary to provide nanoparticle aggregation stability during the combustion process. The classical approach to stabilization of nanoparticles assumes application of different stabilizers, like surfactants or polymers, attached to particles' surfaces, preventing their aggregation via steric or electrostatic repulsion. Thus, the aggregation stability of nanoparticles is determined by the thermal stability of the surfactant-or polymer-based coatings, which is not sufficient for high-temperature processes. In the current study we prepared a catalyst with high thermal stability by immobilization of 10 nm sized MnO x nanoparticles on a surface of 70 nm silica nanospheres. The composition, morphological, and textural parameters of the catalyst were optimized via variation of synthetic conditions. The high catalytic performance of the obtained nanoparticles in heavy oil combustion was proven by evaluation of kinetic parameters of catalytic and noncatalytic processes.

“…It was found that the presence of NiO nanoparticles decreases the oxidation temperature of n-C7 asphaltenes from 450 to 325 °C and the activation energy from 91 kJ•mol −1 for a temperature range between 467 and 514 °C to 57 kJ•mol −1 for temperatures between 280 and 350 °C [41]. Additionally, it has been found for NiO nanoparticles that a smaller particle size generates a greater catalytic effect as observed for the oxidation of quinolin-65 which is an asphaltene model molecule [122] and in the oxidation of n-C5 asphaltenes [123]. Comparing the performance of NiO nanoparticles with other materials, Co3O4 nanoparticles also reduce the n-C7 asphaltenes decomposition temperature to 325 °C.…”

The increasing demand for fossil fuels and the depleting of light crude oil in the next years generates the need to exploit heavy and unconventional crude oils. To face this challenge, the oil and gas industry has chosen the implementation of new technologies capable of improving the efficiency in the enhanced recovery oil (EOR) processes. In this context, the incorporation of nanotechnology through the development of nanoparticles and nanofluids to increase the productivity of heavy and extra-heavy crude oils has taken significant importance, mainly through thermal enhanced oil recovery (TEOR) processes. The main objective of this paper is to provide an overview of nanotechnology applied to oil recovery technologies with a focus on thermal methods, elaborating on the upgrading of the heavy and extra-heavy crude oils using nanomaterials from laboratory studies to field trial proposals. In detail, the introduction section contains general information about EOR processes, their weaknesses, and strengths, as well as an overview that promotes the application of nanotechnology. Besides, this review addresses the physicochemical properties of heavy and extra-heavy crude oils in Section 2. The interaction of nanoparticles with heavy fractions such as asphaltenes and resins, as well as the variables that can influence the adsorptive phenomenon are presented in detail in Section 3. This section also includes the effects of nanoparticles on the other relevant mechanisms in TEOR methods, such as viscosity changes, wettability alteration, and interfacial tension reduction. The catalytic effect influenced by the nanoparticles in the different thermal recovery processes is described in Sections 4, 5, 6, and 7. Finally, Sections 8 and 9 involve the description of an implementation plan of nanotechnology for the steam injection process, environmental impacts, and recent trends. Additionally, the review proposes critical stages in order to obtain a successful application of nanoparticles in thermal oil recovery processes.

“…The NiO NPs were 15 to 30 nm in size, hardly changing if the shape became flat and the atomic distribution increased with further increase in size. The NiO NPs with a size smaller than 30 nm (5 to 15 nm) showed a more robust and a more rapid catalytic performance than those with a particle size of 30 to 40 nm [19].…”
