Spring 2013
For drops sessile on a solid surface, cross flowing air can drive drop oscillation or shedding, based on the balance and interaction of aerodynamic drag force (based on drop size/shape and air speed) and adhesion/capillary forces (based on surface tension and drop size/shape). Better...

Oil Upgrading by Molecular Rearrangement and Cracking: A Study Using Model Compounds and Natural Chabazite
DownloadFall 2015
As demand for fuel increases, new technologies that can convert heavy oil and bitumen into light fuels are needed. Natural zeolites have been proven to catalyze reactions that decrease molecular weight, density, nitrogen, and metals content as well as vacuum residue content when mixed with raw...

The Role of Sulfur during the Cracking of n-Hexadecane and Cold Lake Bitumen with alpha-Fe2O3 and Steam
DownloadSpring 2013
Coke produced during bitumen upgrading has a high heteroatom content and low economic value. To improve feed efficiency, cracking of hexadecane and bitumen with α-Fe2O3 and water has been studied to decrease coke yield, while increasing sulfur content. Compared to thermal cracking, catalytic...
