Biodiesel is always blended with petroleum diesel to serve as the transport fuel, to obtain the specific impact of petroleum diesel addition on thermal degradation for biodiesel
After the quinoline insoluble fraction was removed, petroleum pitch (PP) was brominated under ultraviolet light irradiation for 3 to 9 h with a bromine to PP mass ratio of 1:20 to prepare brominated PPs (BPPs). Synthetic pitches (SPs) were produced…
Growth in the world economy requires an increase in global energy demand. And oil remained the worlds leading fuel, accounting for a third of global energy consumption (BPs Energy Outlook, 2017 edition). However, the amount of conventional light oils…
Phase change material (PCM) is a vital component of thermal energy storage (TES), particularly at a constant temperature. Various organic, inorganic, eutectic, and composite materials are used for storage applications. The major problems with the…
We developed a novel methodology that combines thermo-analytical measurements and mathematical methods to inform the reliable pyrolytic treatment of specific soil/contaminant systems. Our approach improves upon current "black-box" design methods that…
A process engineering strategy was developed for cultivation of high density biomass of Chlorella sp. FC2 with improved productivity under photoautotrophic condition. The process engineering strategy involved a combinatorial approach of: (i)…
In-situ combustion is considered as one of the most effective ways to enhance recovery of heavy crude oils and bitumens. The oxygen from injected air reacts with the heavy components of the crude oil, forming a hot zone in which the cracking and…
In situ combustion (ISC) plays a significant role in the exploitation of heavy crude oil. In this study, the thermal behaviors and kinetics of combustion of heavy crude oil and its saturates-aromatics-reins-asphaltenes (SARA) fractions were…
Cellulose derivatives are widely applied in the field of oil and gas exploration. However, this kind of natural polymers always shows poor temperature resistance due to their organic nature. To improve the temperature resistance of hydroxyethyl…
Oil-dispersed -Fe2O3 nanocatalysts were prepared by coating -Fe2O3 nanoparticles with oleic acid (OA). Mossbauer spectroscopy, X-ray diffraction, and field emission scanning electron microscopy were used to characterize -Fe2O3 and -Fe2O3@OA. Their…
A thermal processing of waste tires in the presence of a natural zeolite catalyst from the "Tayzhuzgen" field (Eastern Kazakhstan) is detailed. The hydrogen sources utilized were heavy residues from oil refinement. The elemental and phase composition…
The importance of the Carmopolis field in Brazil for the exploration of onshore crude oil dates back to 1963. Currently still in operation, this is a major field, serving as a model for enhanced oil recovery tests. In this field, the differences in…
Crude oil palm biomass (OPB) residue is an important source of lignocellulose and could be transformed into biofuels through thermochemical conversion for heat and power in CHP plants or act as sustainable reinforcement in the biocomposite industry.…
To efficiently remove Ni from crude oils and also without corrosion occurring in the process, polymer brush with core-shell structure (PAA@SiO2) was synthesized by radical polymerization, in which micro-sized SiO2 as the core and polyacrylic acid as…
Thermal methods have attracted a significant attention for the extraction of high-viscosity oil and natural bitumen. One of the promising methods for enhanced oil recovery (EOR) is in-situ combustion (ISC). In the reservoir, the combustion process…
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)…
Through silane coupling and free radical polymerization, using SiO2 as core and poly4-vinylpyridine (P4VP) as shell, polymer brush with core-shell structure (P4VP@SiO2) was designed and synthesized. The structure of P4VP@SiO2 was further…
Mixed matrix membranes (MMMs) have received worldwide attention for natural gas purification due to their superior performance in terms of permeability and selectivity. The zeolitic imidazole framework-8 (ZIF-8) blended polysulfone (PSf) membranes…
Petroleum residues with varying cutting depth and corresponding vacuum distillates have been prepared from laboratory deep-vacuum fractionation using unconventional heavy oil (UHO) originated from Venezuela first. They are then sequentially…
The objective of this study was to evaluate the Calotropis procera fiber treated with NaOH combined with heat treatment as sorbent material for removal of petroleum and derivatives in cases of oil spill. The effects of oil viscosity, fiber/oil…
Modern industry strongly relies on the molecular analysis of fossil petroleum and petroleum-derived materials. In the context of a circular economy and carbon neutrality, the chemical description of alternative feedstock materials, such as waste…
In this work, on the example of rock samples from Permian deposits of the heavy oil field from the depth interval 117.5–188.6 m, a comprehensive study of the composition of oil-saturated rocks, as well as thermogravimetric parameters and kinetics of…
