Extended Surfactants: Characterization and Microemulsion Properties
(2008)
Extended surfactants are surfactants with intermediate polarity groups, such as polypropylene oxide (PO) and polyethylene oxide (EO), inserted between the hydrophilic head and the hydrocarbon tail. With this unique molecular ...
Propylene metathesis with rhenium oxide supported by -alumina as catalyst, including kinetic and initial reaction studies.
(1980)
There are seven catalysts studied, i.e., NH(, 4)ReO(, 4)/(gamma)Al(, 2)O(, 3), NH(, 4)ReO(, 4)/TiO(, 2), NaReO(, 4)/(gamma)Al(, 2)O(, 3), NH(, 4)ReO(, 4)/3A(K) zeolite, NH(, 4)ReO(, 4)/3A(Ca) zeolite, NH(, 4)ReO(, 4)/13X(Na) ...
Biosurfactants: Characterization, Microemulsion Formation and Potential Applications
(2009)
Biosurfactants, which are produced from microorganisms, have become of interest due to their non-toxic nature, their biodegradability and their production from renewable resources. Research has evaluated the use of ...
Computational Investigation of the Behavior of Nanoparticles and Surfactants at the Oil-Water Interface
(2021-12)
Surfactants and nanoparticles (NPs) are commonly used to stabilize emulsions, which have found applications in different areas. The fundamental understanding of the behavior of surfactants and NPs adsorbed at the oil-water ...
Applications of multiproperty analysis in the prediction of complex-system thermophysical behavior.
(1981)
Thermophysical-property data for over fifty organic compounds, including high-boiling-temperature hydrocarbons typical of coal-derived fluids, have been used to establish the feasibility of the technique. The overall average ...
Extended Surfactants: Characterization and Microemulsion Properties
(2008)
Extended surfactants are surfactants with intermediate polarity groups, such as polypropylene oxide (PO) and polyethylene oxide (EO), inserted between the hydrophilic head and the hydrocarbon tail. With this unique molecular ...
Analysis of melt blowing dies using computational fluid dynamics .
(2007)
For a single annular jet and the blunt slot die, a previously developed rheological model was used to predict the fiber diameter, velocity, and temperature. Then, these were used to set boundary conditions in simulations ...
Simultaneous cracking of phenolic compounds and hydrocarbons over zeolites
(2014)
Co-processing bio-oils with hydrocarbons in conventional refinery processes has been considered as a promising strategy for upgrading and producing fuels from alternative sources. Co-feeding the phenolic fraction to the ...
Investigating basic characteristics of turbulence in channel flows using Lagrangian concepts
(2012)
Many examples of turbulent motion of particles in nature can be better perceived through the concept of backwards turbulent dispersion. Some examples include pollutants in atmosphere or oceans reaching populated human or ...
