Vapor-liquid equilibria in the system hydrogen-nitrogen-carbon monoxide
Vapor-liquid equilibrium compositions for the system hydrogen-nitrogen-carbon monoxide were determined at -310°F, and -280°F and -240°F from 300 psig to the critical. PVT data for hydrogen were fitted to the ...
Effects of the decay of sulfur-35 on some electrical properties of cadmium sulfide semiconducting films
The vacuum behavior of radioactive and non-radioactive semiconducting films of CdS has been studied as a function of time in order to determine the effect of radioactive doping. Radioactive films containing S35 were made ...
Low temperature vapor-liquid equilibrium in light hydrocarbon mixtures: Methane-ethane-propane system
Experimental equilibrium data have been determined for 175 mixtures of methane, ethane, and propane. The investigation included temperatures from 50°F to -200°F and pressures up to the critical. A vapor recycle ...
A study of alumina silicon fluoride combinations as hydrocarbon conversion catalysts
The purpose of this work was to study the influence of certain variables in the preparation of an alumina-silicon-fluoride complex on its behavior as a cracking catalyst.
Molecular modeling the microstructure and thermodynamic properties of complex fluids
The accurate prediction of a complex fluid's equilibrium microstructure and corresponding thermodynamic properties relies on the capability to describe both the molecular level architecture and specific governing physics. ...
Sapling growth and recruitment as affected by flooding and canopy gap formation in a river floodplain forest in southeast Texas
I used sapling population data collected since 1980 to investigate how canopy disturbance interacts with chronic understory disturbance to determine regeneration patterns. I reconstructed flooding history using a combination ...
Understanding Structure-Property Relationships for Palladium-Gold Nanoparticles as Colloidal Catalysts
Bimetallic palladium-gold (PdAu) nanoparticle (NP) catalysts have been demonstrated for the better catalytic performance than monometallic Pd catalysts in various reactions; however, the enhancement mechanism is not ...
Diluted bitumen emulsion characterization and separation
Stable water-in-oil emulsions persist in bitumen froth from surface mining process of Athabasca oil sands because of asphaltenes and clay solids. This dissertation focuses on the characterization and separation of water ...
Modeling of asphaltene precipitation and arterial deposition
The potential problem produced by asphaltene deposition during oil production has motivated the development of several experimental techniques and theoretical models, trying to understand and predict the asphaltene behavior. ...
Study of Foam Mobility Control in Surfactant Enhanced Oil Recovery Processes in One-Dimensional, Heterogeneous Two-Dimensional, and Micro Model Systems
The focus of this thesis was conducting experiments which would help in understanding mechanisms and in design of surfactant enhanced oil recovery (EOR) processes in various scenarios close to reservoir conditions such as ...
