Structural modifications of petroleum pitch and its subfractions induced by mild air-blowing modification have been monitored by elemental analysis, average molecular weight, Fourier transform infrared spectrometer (FTIR),1H nuclear magnetic…
Gasification is an efficient and environmentally friendly treatment process for petroleum coke. But the rheology and stability of petroleum coke-water slurries (PWS) do not meet the feeding requirements of gasification. This study blends Hami coal…
The current study investigates the synergistic/antagonistic effect of cationic (octyl pyridinium chloride [C8Py][Cl]), anionic (sodium lauryl sulfate (SLS)), and nonionic (octyl phenol ethoxylate (Triton-X100)) surfactants on the interfacial tension…
The coulometric method of measuring humidity and oxygen on the basis of an electrolytic cell with a film of phosphorus oxide for continuous analysis of natural gas in pipelines of its transportation is considered. On the basis of the method the…
Abstract: General features of the distribution of vanadium and nickel in the products of two-step solvent fractionation of asphaltenes have been using the exampley of heavy crude oils from various fields of the VolgaUrals oil-and-gas basin (Russia).…
Bioremediation is a low-cost approach for crude oil spill remediation, but it is often limited by electron acceptor availability. In addition, the biodegradation products of crude oil contaminants are complex, and transformation pathways are…
