In this work, Fe2O3, ZnO, and MgO nanoparticles were synthesized via a chemical precipitation method to investigate their effects on wax formation, morphological characteristics, and rheological behavior in a crude oil sample. For this purpose,…
Crude oil is normally produced in the form of a water-in-oil (W/O) emulsion. One of the major challenges during crude oil exploration is the high viscosity of crude oil produced due to the formation of stable emulsions. This affects the overall cost…
Due to advances in hydraulic fracturing and horizontal drilling, the abundance of inexpensive natural gas has revolutionized the energy industry. As the world population increases, natural gas will play a prominent role in satisfying new energy…
N-doping can endow carbon materials with high electrochemical activity. Besides the widely validated sp2-hybridized nitrogen doping, sp-hybridized nitrogen (sp-N) atoms are also expected to be new active sites. However, both sp-N atoms and cyano (CN)…
The so-called blue hydrogen production process, integrates conventional fossil fuel-based production methods with carbon capture and storage technologies. This combination reduces total CO2 emissions, compared to conventional grey fossil-fuel-based…
Concentrating solar power (CSP) plants have been widely commercialized for generating electricity from solar energy. Thermal energy storage (TES) systems have been deployed as a key component in CSP plants for resolving the supply-demand gap during…
Multi-functional protective epoxy coatings were applied to display synergistic resistance properties on the steel/coating interfacial zone of petroleum storage tanks (PST). This work investigated the synthesis of new mixed Ni(II), Pd(II), and Cd(II)…
This study aims to design a novel green nanocomposite based on the synergistic effect between silica nanoparticles (SN) and cardanol (CDN). The latter is an environmentally friendly dispersant compound extracted from the cashew nut shell waste. Three…
Nuclear magnetic resonance (NMR) well logging tools are being commercially utilized for the characterization of various fluids confined within reservoir rocks. Conventional NMR T2-distribution measurements are unable to quantify the actual fractions…
Novel edge-capped ZrO2 nanoparticles on V2O5 nanowires were successfully synthesized through a simple, eco-friendly, and inexpensive hydrothermal technique. The as-prepared nanostructures were characterized using various measurements to study their…
In this work, nanocatalysts as Ni, Mo, Fe nanoparticles (NPs) were synthesized by the modified inverse microemulsion method at room temperature conditions in order to apply them to heavy crude oil (HCO) in situ hydroprocessing and to improve their…
A new series of sulfobetaine surfactants with double-chain single-head structure were derived from 1,3-dialkyl glyceryl ethers and their performances in reducing Daqing crude oil/connate water interfacial tension (IFT) in the absence of alkali were…
In this work, the effects of four different chemical inhibitors, namely a polymeric surfactant, synthesized -Al2O3/NiO nanoparticles, epoxy resin, and canola oil to inhibit asphaltene precipitation in three different crude oils collected from various…
Abstract: Asphaltene is the heaviest organic compound in crude oils that its precipitation and deposition cause many negative effects on oil production such as an overall decrease in production rate and an increase in operating costs. Nanoparticle…
A new class of magnetically responsive and interfacially active Janus (MJanus) nanoparticles was designed and synthesized by sequential adsorption of cellulosic materials: hydrophobic ethyl cellulose (EC) and hydrophilic carboxymethyl cellulose (CMC)…
We proposed a direct in situ synthesis method for iron oxide nanoparticles (NPs) along with catalytic erformance upgrading of heavy crude oil (HCO). Our method compares the upgrading of a HCO where other iron oxide nanoparticles were synthesized by a…
The aim of the current study was to investigate and study adsorption and nanofiltration systems for separation of total petroleum hydrocarbons (TPH) from wastewater generated by an oil refinery in Bushehr, Iran. In the first step (previous study),…
As reserves of conventional light oil become depleted, recovery of viscous oil is urgently needed to meet increasing energy demands worldwide before clean energy sources are fully developed. Current oil extraction technologies suffer from low…
