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.
The compressibility factors and second virial coefficients for helium-nitrogen mixtures at low temperature and high pressure
The Burnett method was used to determine the volumetric behavior of helium, nitrogen, and six evenly spaced helium-nitrogen mixtures at low temperature and high pressure. Compressibility isotherms were determined for both ...
Structure, wettability, and barrier properties of self-assembled monolayers on metallic surfaces
Self-assembled monolayers (SAMs) offer a convenient approach for fabricating molecularly tailored interfaces with well-defined compositions, structures, and thicknesses. SAMs have been suggested for use as corrosion barriers, ...
Engineering palladium-on-gold bimetallic nanoparticles as groundwater remediation catalysts
Over the years, our groundwater sources have become contaminated with chlorinated organics, in particular trichloroethene (TCE) due to its exposure as a solvent to degrease metals and electronic parts in the automotive, ...
Effects of irradiation on the catalytic activity of metal oxides
This work further develops a technique for changing the electronic and defect structure of magnesium oxide and silica gel catalysts. Relatively small doses of ultraviolet and neutron irradiation have been found to enhance ...
Finite element methods for viscoelastic fluid flow simulations: Formulations and applications
Complex fluid flow simulations are important in several industrial and biological applications, e.g., polymer processing, ink-jet printing, and human as well as artificial organs, and they pose several numerical challenges. ...
The study of high pressure vapor-liquid equilibria by gas-liquid partition chromatography
A method has been investigated for measuring vapor-liquid equilibrium ratios, or K-values, of a solute distributed between a gas phase and a non-volatile liquid phase. A gas-liquid partition chromatographic technique is ...
Solvothermal Synthesis and Supported Catalysis of Polyanion-derived Metal Oxide Nanoparticles
Supported metal oxides (SMOs) are important catalytic materials that find numerous applications in important industrial processes. Improving the structural properties of SMOs is a challenging objective due to material ...
