Scope: The procedures in this test method cover the determination of organic chloride (above 1 g/g organically-bound chlorine) in crude oils, using either distillation and sodium biphenyl reduction, distillation and microcoulometry, or distillation…

N-doped TiO2/ reduced graphene oxide (N/TiO2/rGO) composite was prepared and used together with the commercial TiO2 for comparative research on photocatalytic degradation of crude oil in seawater. Five test conditions were designed including a…
1-Ethyl-3-(3-dimethylaminopropyl) carbodiimide (EDC) is widely used as a crosslinker for fluorescence labeling of protein in the fields of biochemistry and food analysis. Many natural polysaccharides often contain some proteins or peptides that are…
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…
Recent analytical advances have provided evidence that groundwater affected by oil sands process-affected water (OSPW) is reaching the Athabasca River at one location. To understand and discriminate the toxicological risks posed by OSPW-influenced…
This work focused on the evaluation of extraction protocols using convective heating and HNO3 or HCl solutions regarding their performance towards fractionation analysis of mercury (inorganic and organic fractions) in oily sludge samples using cold…
Abundant measured data from source rocks, crude oils and oil inclusions in the Dongying Depression were used to identify the oil generation, expulsion and cracking stages under geological conditions, so as to build a fluorescence evolutionary model…
Crude oils produced from different reservoirs in the world have very different chemical compositions and physicochemical properties. Naphthenic acids and sulphur content can affect the properties and impact the processing and refining of oils.…
Abstract: In this study the surface of bio-based polyurethane foam was enriched with different contents of catalyst residue from the petroleum industry. The foams were prepared with different residue contents, 20, 50, and 80 wt% relative to the total…
