Sulfoxide Surfactants
(2018-08)
A novel group of nonionic surfactants, which we term ester sulfoxides, derived from 2-hydroxy-4-(methylthio) butyric acid are characterized in this thesis. The physico-chemical properties, equilibrium and dynamic properties, ...
Application of electrochemical technique to measure mass transfer of macromolecules in a flow system.
(1980)
Steady state voltammetry and the scanning methods were used to obtain voltammograms (current-potential curves) with well defined mass transfer regions.
PRODUCTION OF ALKYL-AROMATICS FROM LIGHT OXYGENATES OVER ZEOLITE CATALYSTS FOR BIO-OIL REFINING
(2010)
Upgrading of light oxygenates derived from biomass conversion, such as propanal and glycerol, to more valuable aromatics for biofuels has been demonstrated on zeolite catalysts. Aromatics with a high ratio of C9/(C8+C7) ...
FISCHER-TROPSCH SYNTHESIS ON HYDROPHOBIC CATALYSTS IN BIPHASIC MEDIA
(2018-12-14)
Fischer-Tropsch (FT) synthesis stands out as a relevant alternative technology for the production of liquid fuels. Natural gas, coal, biomass and other carbon-containing raw materials can be converted to syngas (CO and ...
An investigation into the properties and behaviors of alkyldiphenyl oxide disulfonate surfactants.
(2001)
An overview of surfactant adsorption included a discussion of the importance of surfactant adsorption in petroleum applications, a summary of the history of surfactant adsorption research and the mechanisms that have been ...
Carbon dioxide extraction of ethanol from water at elevated pressures /
(1982)
Experimental results from the continuously fed apparatus demonstrate that a 23.4% conversion of a 49.5 mole% ETOH-H(, 2)O feed stream to an 88 mole% ETOH-H(, 2)O overhead stream may be accomplished with liquid carbon dioxide ...
Technical and economic feasibility study of polyelectrolyte-enhanced ultrafiltration (PEUF) for the removal of multivalent ions from water.
(1998)
The results of this work were modeled using an ion-binding model based on a two-phase approximation theory to predict rejection of the hardness ions. The model is highly accurate in prediction of rejections at low ...
Electrically conducting polymer matrix composites: A morphological and structural perspective.
(1998)
Wide angle x-ray scattering (WAXS), conductivity, optical microscopy, stress relaxation, and differential scanning calorimetry (DSC) measurements, were used to show the effect of filler addition and uniaxial orientation ...
