Rheology of Structured Oils

Journal of Engineering Physics and Thermophysics, 2017
Rheological models of structured oils are proposed and compared with available experimental data on oils from different deposits. It is shown that structured oils can possess properties of Bingham and power-law non-Newtonian fluids.

The Colloidal Structure of Crude Oil and the Structure of Oil Reservoirs

Energy & Fuels, 2007
Large sand bodies in the subsurface are shown to provide a unique laboratory for understanding both reservoirs and crude oils. Here, we treat the discovery by downhole fluid analysis of a gravitational concentration gradient of asphaltenes, the most dense component of crude oil, in a 2500-ft column of crude oil in the reservoir. The continuous trend of

Oil bodies (oleosomes): Occurrence, structure, allergenicity

Revue Française d'Allergologie, 2018
Abstract Oil bodies, or oleosomes, consist of lipid droplets confined within a protein-containing lipid monolayer that are widely distributed in oil seeds, particularly edible oil seeds. Amphiphilic proteins embedded in the lipid monolayer form an interface between the hydrophobic core of the oil bodies and the hydrophilic cytoplasm in which these ...

Oil structuring using polysaccharides

Current Opinion in Food Science, 2019
Oil structuring or oleogelation is a promising strategy to formulate oil-based soft matter for various applications. Such soft matter can be formulated using structuring agent with an oil phase. In the literature one can find various structuring agents that differ in their molecular weight; low or high molecular weight oil gelators (LMOG and HMOG ...

Structured polyurethanes for oil uptake

Journal of Applied Polymer Science, 2005
AbstractIn an attempt to develop a desirable resin formulation for spilled oil absorption, segmented polyurethanes of various types and lengths of hard and soft segments have been synthesized and tested for X‐ray diffraction, thermal, mechanical, and dynamic mechanical properties in addition to oil and water absorptions.

Colloidal structures in natural oils

Current Opinion in Colloid & Interface Science, 2010
Natural oils are in general mixtures of triglycerides of various fatty acids containing also small quantities of a multitude of other molecules, the minor components. Their composition depends on the type of their sources, either vegetable or animal, and on agronomic and climatic conditions. Extraction process highly influences the final composition of

Multiphase Structure of Bio-oils

Energy & Fuels, 2005
The multiphase complex structure of biomass pyrolysis oils can be attributed to the presence of char particles, waxy materials, aqueous droplets, droplets of different nature, and micelles formed of heavy compounds in a matrix of hollocellulose-derived compounds and water.

Composition and Structure of the Oil Sediments of Resinous Oil

Химия твердого топлива, 2023
The study of the distribution of sediment formed from test oil on the sediment-forming surface at different temperature gradients was typical for resinous oils: the amount of oil sediment increased with decreasing oil temperature, and its maximum corresponded to temperatures closest to the pour point of oil.

Flow structure in horizontal oil–water flow

International Journal of Multiphase Flow, 2000
Summary: The flow structure occurring during the cocurrent flow of oil (1.6 mPa s viscosity and 801 kg/m\(^{3}\) density) and water was investigated using two 1-in. nominal bore horizontal test sections made from stainless steel and acrylic resin respectively.

FCC coprocessing oil sands heavy gas oil and canola oil. 1. Yield structure

Fuel, 2015
Abstract Reducing the carbon footprint or GHG emissions is a major challenge during the production and processing of Canadian oil sands bitumen for clean transportation fuels. Co-processing bitumen derived feeds and biomass may provide an alternative solution since the level of GHG emissions for producing renewable biofuels is considered ...
