1. The asphaltenes of Arlan high-sulfur crude represent a multicomponent, polydisperse mixture, which is separated by precipitation chromatography into fractions differing in density, molecular weight, elemental composition, and spectral characteristics. 2. In the light fractions of the asphaltenes, the ...

An experiment was conducted in the Teaching and Research Farm of the Faculty of Agriculture and Veterinary Medicine, Imo State University, Owerri, Nigeria to investigate the potentials of using poultry manure and cow dung as bioremediants for crude oil p
Chemical Properties of Crude Oil In terms ofItsfundamental chemistry, oil consists largely of carbon and hydrogen with traces of oxygen, sulfur, nitrogen, and a rather unusual range of metals which includes vanadium, nickel, and others. Though the composition of oils is relatively straightforward, ...
In the present study, the effects of crude oil contamination during oil exploration on soil physical and chemical properties were investigated in marshes of the Momoge National Nature Reserve in Jilin Province, China. The concentrations of total petroleum hydrocarbons in the marsh soil near the oil...
This result helps to complete the picture of the complex correlation between rheological and chemical–physical properties of heavy crude oils. While it is accepted that chemical-physically different samples may, or may not, have a different rheology, we show for the first time that unperturbed ...
Ultimately, this information determines the ability of a lubricant to meet certain goals and benchmarks. Read on to find out more about why the physical and chemical properties of lubricants are so important and how these variables are used to help determine factors like quali...
Characterization of the physical and chemical properties of the distillate fractions of crude bio-oil produced by the glycerol-assisted liquefaction of swi... The distillation curves of crude bio-oil from glycerol-assisted hydrothermal liquefaction of swine manure were measured. The crude bio-oil had...
The acid and iodine values of field pennycress oil were lower than those for cress oil, but both oils had excellent lubrication properties. 展开 关键词: Cress Field pennycress Lepidium sativum Physical properties Phytosterols Thlaspi arvense Tocopherols Vegetable oil ...
