Conformance Control through In-situ Gelation of Silica Nanoparticles

Rankin K.M., Nguyen Q.P., The University of Texas at Austin, US

Due to reservoir heterogeneities, oil recovery from fluid injection during secondary and/or tertiary recovery does not occur in an ideal piston-like displacement. Rather sweep efficiency can be much lower than 100% due to heterogeneities such [...]

Molecular Dynamics Simulation of Adsorption from Microemulsions and Surfactant Micellar Solutions at Solid-Liquid, Liquid-Liquid and Gas-Liquid interfaces

Akkutlu Y., Bui K., Silas J.A., Zelenev A., Saboowala H., Texas A&M University, US

In enhanced oil and gas recovery, the production of hydrocarbons is influenced by the ability of injected surfactants to adsorb and to modify interfacial tension at different interfaces. It has been demonstrated that surfactant and [...]

Capturing and Using CO2 as Feedstock for Clean Chemical Processes Technologies

Demirel Y., University of Nebraska Lincoln, US

Chemical-looping technology for capturing CO2 are discussed with critical assessments of the circulating fluidized bed systems and the packed bed reactor with periodic switching of the feed streams of fuel and air. Beside, some industrial [...]

Pelletized silica and polyethyleneimine composites for CO2 capture via adsorption

Knowles G.P., Chaffee A.L., Monash University, AU

Amine adsorbent powders are of broad interest to facilitate CO2 capture towards reducing atmospheric greenhouse gas. It is recognized, however, that industrial adsorption processes require pelletized rather than powdered adsorbents. Mesoporous silica and branched polyethyleneimine [...]

Development of the Novel Functionality of Probiotics Fermented Noni Hydrolysates

Yin L.J., Lee H.-H., Wu J.J., Jiang S.T., National Kaohsiung Marine University, TW

This study aimed to help the release of functional nutrients from noni fruit by enzymatic hydrolysis, and to subsequently shorten the fermentation time during the biotransformation of some compounds. This study firstly investigated the optimal [...]

Commercial pilot for closed-loop wastewater treatment and biofuel production using microalgae

Atwood M., Novoveska L., Sundstrom E., Valdez P., Algae Systems LLC, US

In wastewater treatment, significant energy is used to dilute, discharge, or landfill valuable resources. This situation is untenable due to energy costs and global scarcity of clean water. Algae Systems has developed and patented a [...]

Carbon Nanotube Matrices for implantable Biofuel Cell design

Holzinger M., Le Goff A., Cosnier S., CNRS - University of Grenoble, FR

Glucose biofuel cells are promising candidates to supply implanted electronic devices by converting the chemical energy of glucose, present in body fluids, into electric power. Before such biofuel cells can become realistic alternatives compared to [...]

Analysis of low temperature effects on the performance of SEPIC in a fuel cell system

Noh M.D., Kim S., Park Y.W., Chungnam National University, KR

A single-ended primary-inductance converter (SEPIC) is to be used at the output of a direct-methanol fuel cell (DMFC) system. In this paper, SEPIC is investigated in terms of the performance variations when the operating temperature [...]

Enhanced fuel cell performance with modified Nafion® membranes

Krishnan L., Yeager G., Clark K., Kerr J., Soloveichik G., Miebach T., GE Global Research, US

The interaction of Nafion® 212 membrane with a carbocyclic fuel, decalin was studied. Decalin treatment of N212 improved vapor sorption and membrane conductivity. In addition a substantial increase of peak power in a H2/Air fuel [...]

Molecular Hydrogen Storage in Fullerenes for Use on Board Fuel Cell Vehicles – A Density Functional Theory Study

Durbin D.J., Allan N.L., Malardier-Jugroot C., Royal Military College, CA

Hydrogen gas is a potential fuel to replace gasoline on board vehicles. However, viable storage methods must be developed. Carbon nanomaterials are promising because they are cheap, lightweight and abundant but carbon-hydrogen physisorption is weak [...]
