Spring 2016
This work investigated different acid catalysts and olefinic alkylating agents for the alkylation of an industrial asphaltenes feed. The working hypothesis was that alkylation would change the solubility parameter and increase the H/C ratio of asphaltenes sufficiently to cause some asphaltenes...

Spring 2014
Crude oils contain a distribution of molecules with diverse chemical structures and molecular weights. Asphaltenes are considered the most problematic of these structures. We have investigated the adsorption and aggregation of asphaltenes on surfaces using scanning probe microscopy. Modifying the...

Spring 2016
Asphaltenes are a solubility class and it is the material in oil that is insoluble in a paraffinic matrix. It is a major contributor to problems in many petroleum operations such as production, transportation, refining, precipitation, crude oil emulsification, and de-emulsification, and high...

Extending Depletion Flocculation Phase Behavior Models to Partially Soluble and Aggregating Colloids—Asphaltenes
DownloadFall 2015
Mixtures of colloids + non-adsorbing polymers + good solvents are well known to exhibit multiphase behaviors that are driven by the depletion flocculation mechanism where one phase, designated a colloid gas, is largely comprised of polymer and solvent, while the other phase, designated a colloid...

Rheological behavior and nano-microstructure of complex fluids: Biomedical and Bitumen-Heavy oil applications
DownloadFall 2010
The main objective of this research was to exploit the interrelations between the rheological behavior and nano-microstructure of complex fluids in solving two state-of-the-art problems, one in the field of biomedical engineering: controlling the amount and characteristics of bioaerosol droplets...

Fall 2011
This research was undertaken to study the performance of paraffinic solvents at higher temperatures for heavy oil/bitumen recovery. Heavy oil or bitumen saturated glass bead packs, Berea sandstone and carbonate cores were used in the experiments to represent different types of pore structures,...

Probing the Molecular Interactions of Asphaltenes in Organic Solvents Using a Surface Forces Apparatus
DownloadSpring 2014
A fundamental understanding of the stability of water-in-bitumen emulsions stabilized by surface active agents requires a good description of the molecular interactions between the different materials in contact. Of these surface active agents, asphaltenes and oil contaminated fine solids are...

A flow-through enzymatic microreactor for the rapid conversion of triacylglycerols into fatty acid ethyl ester and fatty acid methyl ester derivatives for GC analysis
Download2015
Mugo, Samuel M., Anuar, Sabiqah T., Curtis, Jonathan M.
A flow-through enzymatic microreactor for the rapid conversion of triacylglycerols (TAG) into fatty acid ethyl ester (FAEE) or fatty acid methyl ester (FAME) derivatives was developed. The microreactor was a porous silica monolith fabricated within a 320 μm ID fused silica capillary with lipase...
