Anticipation of alternative road binder to replace petroleum derived bitumen requires a deep understanding of relationships between the chemical composition of bitumen and their physical properties, especially rheological ones. The vast number of the…
Fractions of coal tar and coal direct liquefaction oil were selected as the research objectives, and they were analyzed by GC-MS/FID (Gas Chromatography-Mass Spectrometer/Flame Ionization Detector), where MS was used for qualitative analysis and FID…
The ability of an injected gas to dissolve crude oil hydrocarbons may be a major factor controlling the success of enhanced oil recovery (EOR) projects in unconventional reservoirs. Multiple laboratory gas injection tests were conducted using Bakken…
Incremental oil recovery due to polymer flooding results from acceleration of oil production along flow paths and improving sweep efficiency. To achieve favorable economics, polymers should have a high viscosifying power and low adsorption. However,…
The value-added utilizations of technical lignin are restricted by its heterogeneous features, such as high polydispersity, complex functional group distribution, ununiformed reactivity, etc. Fractionation of lignin into more homogeneous parts…
Petroleum sulfonates are widely used in chemical flooding in China. The samples are complicated and not all the fractions are effective. To recognize effective fraction with excellent interfacial activity and emulsifying property, a preparative…
