Fall 2012
The most prevalent oxidation states of vanadium in nature are V(IV) and V(V). Toxicity of vanadium increases with increasing oxidation state. A high-performance-liquid-chromatography inductively-coupled-plasma mass-spectrometry method was optimized for the speciation of V(IV) and V(V). It was...

Fall 2012
The kinetics of vapor phase cracking of bitumen derived heavy gas oil and the quality of liquid products were investigated at temperatures of 600-700 °C. Fixed and condensed gases were analyzed by gas chromatography. The quality of liquid products was characterized using simulated distillation,...

Vapour-Liquid Equilibrium of by-Products n-Alcohols and 1,3-Propanediol from Polyol Production
DownloadSpring 2013
A new method for collecting vapour-liquid equilibrium data for binary mixtures is proposed in this work. A modified differential scanning calorimetry technique was used by evaluating the sample temperature instead of the heat flow. This method was tested on three well known systems and the...
