Gas-Assisted Gravity Drainage – A New Process for CO2 Sequestration and Enhanced Oil Recovery

Rao D.N., Louisiana State University, US

The current commercial practice of gas-based enhanced oil recovery processes involves either continuous gas injection (CGI) or Water-Alternating-Gas (WAG) injection. Over 60 commercial projects in West Texas and other parts of the world have amply [...]

Theoretical Synthesis of Mixed Materials for CO2 Capture Applications

Duan Y., DOE-National Energy Technology Laboratory, US

Since the current technologies for capturing CO2 are still too energy intensive, to develop new materials that can capture CO2 reversibly with acceptable energy costs are needed. By combining thermodynamic database mining with first principles [...]

Inert, Corrosion Resistant CVD Coating for Oil and Gas Service

Mattzela J.B., Smith D., Yuan M., Higgins M., Barone G., SilcoTek Corporation, US

Estimates of the cost of corrosion within US industries often exceed $150 billion. Challenges within the often complicated production techniques of the oil and gas industry have led to increased efforts to control these costs. [...]

Development of New Surfactants for CO2 Foam Enhanced Oil Recovery

Nguyen Q.P., Ren G., The University of Texas at Austin, US

Sweep efficiency in CO2 enhanced oil recovery processes are major problem owing to the unfavorable mobility of CO2. One method of controlling CO2 mobility is through the use of foam. CO2 foam in the past [...]

Multifunctional Nanocomposites for Oil and Gas

Sherman A., Powdermet Inc/Terves Inc, US

The ability to design and manufacture highly engineered multiphase materials enables the independent (actually interdependent) control over physical and mechanical properties, and kinetic response of structural materials. The production of "materials that do more" offer [...]

Computational study of structural dependence of catalytic properties of Pt-Ru nanoalloy catalysts

Prasai B., Petkov V., Central Michigan University, US

Metal nanoparticles (NPs), composed of single-type metals and multiple-type metals, have attracted a great deal of interest in the research community since such NPs are key components in many useful applications such as catalytic, magnetic [...]

Cellulose Fiber Immobilized Silver Nanoparticles and Their Applications in Catalysis, SERS and Antimicrobial Activity

Baruah B., Kennesaw State University, US

This work involves in-situ preparation of silver nanoparticles on nonwoven fibers in baby wipes (a mixture of synthetic fiber and cellulose fiber) by impregnating Ag+ ions. The Ag+ ions in the micronanopores of the fibers [...]

Low Temperature Plasma Surface Treatment of Catalytic Material

Miley G.H., Srivastava S., Kim K-J, Chen G., Uiversity of Illinois and NPL Associates, US

We are developing a low temperature plasma treatment to modify the surfaces of various heterogeneous catalytic materials. The plasma modification has been shown to radically change the surface morphology of various catalytic materials including nickel, [...]

Tailoring Particle Behavior for Phase Transfer Catalysis: Recent Developments by the Center for Interfacial Reaction Engineering

Aichele C.P., Weston J., Venkataramani D., Briggs N., Crossley S., Harwell J., White J., Resasco D., Oklahoma State University, US

This presentation highlights recent advances by the Center for Interfacial Reaction Engineering (CIRE) in designing and tailoring catalytic particles for use in phase-transfer catalysis. CIRE consists of researchers across several disciplines including nanotechnology, thermodynamics, interfacial [...]

Optimization of Catalyst Nano-structures through Alloying and De-alloying Process—Research on Ag-Co catalyst for Catalytic Oxygen Reduction in Alkaline Media

Jiang R., U.S. Army Research Laboratory, US

Optimization of particle size and particle’s nano-structure at the atomic level can precisely and effectively tune catalytic properties of materials, and enabling enhancement in both catalytic activity and stability. We synthesized a highly active and [...]
