DOWNLOAD EBOOKProvides insights into the composition of petroleum, especially its heavy ends, and presents a review of modern methods for the analysis of heavy petroleum fractions, which are viewed as refinery feedstocks. The concept of an atmospheric equivalent boiling point (AEBP) scale increasing the boiling range almost threefold and allowing for the description of all crude oil fractions is introduced.

DOWNLOAD EBOOKHydrocarbon-based liquid crystal domains have been identified in unreacted heavy fractions of petroleum from Athabasca bitumen and other hydrocarbon resources worldwide. These liquid crystal domains have also been shown to transfer from the hydrocarbon-rich phase to the water-rich phase during SAGD production, and primary separation of mined bitumen where their composition is enriched relative to bitumen and inorganic constituents. In this work, liquid crystal rich material was further isolated from SAGD produced water that also contains dispersed drops of bitumen rich material mineral matter and clay among its constituents. The physical and chemical isolation methods are described and the outcomes are validated using cross-polarized light microscopy and chemical analysis, including: elemental analysis and Fourier Transform Ion Cyclotron Resonance Mass Spectrometry (FT-ICR MS) using a negative-ion Electrospray Ionization (ESI) source (heteroatom class distributions, detailed DBE and O/C ratio). From the elemental and other analyses, the liquid crystal rich material is shown to include humic substances (humic acid, fulvic acid, humin) among the principal components as these are the only categories of species known to be present that have high enough oxygen contents to meet the mass balance constraint imposed by the elemental analysis. Naphthenic acids and other potential candidate species do not have high enough oxygen contents comprise a significant mass fraction of the constituents.

DOWNLOAD EBOOKThe first strand involves a critical overview of the design of experimental methods used for examining the thermal behaviour of solid fuels [pyrolysis, liquefaction and gasification], while the second will emphasise chemical structures and molecular mass distributions of coal derived tars, extracts and pitches, petroleum-derived asphaltenes, and biomass derived heavy hydrocarbon liquids.Two major, interdependent strands in the study of fossil and renewable fuel utilisation are focused on within this text:(i) Thermal characterisation of solid fuels including various ranks of coals, biomass and waste, and, (ii) The analytical characterisation of heavy hydrocarbon liquids, covering coal, petroleum and biomass derived heavy fractions.Two major, interdependent strands in the study of fossil and renewable fuel utilisation are focused on within this text: (i) Thermal characterisation of solid fuels including various ranks of coals, biomass and waste, and, (ii) The analytical characterisation of heavy hydrocarbon liquids, covering coal, petroleum and biomass derived heavy fractions.

DOWNLOAD EBOOKAlthough there is a shortage of light petroleum, there is plenty of heavy petroleum rich in macromolecules available, creating an increasing interest for processes that can convert heavy oils to light oils. Process Chemistry of Petroleum Macromolecules provides the scientific basis for such processes, presenting methods to determine improvement potential. Topics include characterization, thermal kinetics, phase behavior, and separation. Revealing that the science of petroleum macromolecules is simpler and more exciting than imagined, it also discusses macromolecules that self-associate, liquid crystalline phases, reactions triggered by phase separation, and both dispersed and dissolved solutes.
