This work proposes a novel method of temperature prediction during heavy oil in-situ combustion according to the fuel availability (FA) of true boiling point fractions, which is also called pseudo-components. Six kinds of n-alkanes with different carbon number and three crude oil samples from Karamay oil field were used and each oil sample was chosen to get seven true boiling point (TBP) fractions...
Phosphogypsum (PG) is a by-product in the phosphate fertilizer industry, and low rank coal-lignite has high moisture which seriously influence its direct use. As a promising raw material for chemical industry, syngas can be obtained through a properly designed lignite Chemical Looping Gasification (CLG) of PG oxygen carrier. The understanding of the reaction mechanism has been developed, while optimal...
Bio-crude obtained from algae by hydrothermal liquefaction (HTL), is considered to be one of the major emerging fuel feedstocks and, as such, has drawn considerable attention from a number of researchers. However, its complex composition has stifled the development of this material in the effort to utilize it as a replacement for conventional petroleum transportation fuels. In addition, the high nitrogen...
Ionic liquids (ILs) were considered to be immobilized on solid supports to overcome the problems of the pure ILs in fuel desulfurization. Take Merrifield resin as solid support, four polymer-supported imidazole ionic liquids (PSILs) with different lengths of alkyl chain linkers were prepared by covalent binding and the structures were characterized by Fourier transform infrared (FTIR), elemental analysis,...
ImCl-silica gel (SG-ImCl) was prepared by directly immobilized [1-methylimidazole][Cl] (ImCl) onto silica gel (SG) using co-condensation of ionic liquid modified organosilane and tetraethoxysilane (TEOS) as silica source in strong acid condition. The properties of the samples were characterized by FTIR, elemental analysis, 29Si MAS NMR, SEM, BET. The results suggested that [1-methylimidazole][Cl]...
This paper is concerned with the study of the effect of the molecular structure of surfactant on the reduction of interfacial tension of Enhanced Oil Recovery (EOR). The interfacial tension behavior of nonane and crude oil with three hexadecylbenzene sulfonate isomers (with benzene rings located at different positions along the alkyl chains) were investigated. It was found that the interfacial tensions...
