Experimental Determination of Carbon Capture and Sequestration Response to Reservoir Quantities

Abunumah O., Ogunlude P., Gobina E., Centre for Process Integration and Membrane Technology, School of Engineering, The Robert Gordon University, Aberdeen, UK

Reservoir entities can be classified into geological, geometrical and fluidic. To complicate matters, reservoirs are usually set in geological layers, such that each layer interacts with injected and resident fluids differently. Carbon dioxide (CO2) is [...]

Laser precipitation of Eu and Yb codoped CaF2 nanocrystals on the surface of glass and emission characteristics

Kim D.S., Bae C-H, Lim K-S, Chungbuk National University, KR

We precipitated spatially selective Eu/Yb doped CaF2 nanocrystals on the surface of glass by CO2 laser irradiation. Because of low phonon energy of CaF2, we observed several times enhancements in down-shift emission under 365 nm [...]

CO2 reforming of CH4 by the combination of dielectric barrier discharge plasmas and zeolite catalysts

Nguyen H.H., Kim K.S., Kangwon National University, KR

Dry reforming of two green-house gases (CH4 and CO2) to convert to syngas (mixture of CO and H2) has gained deep research interests lately. Several technologies were proposed to convert the CO2 and CH4, such [...]

Mesoporous Zirconia Supported Nickel Catalysts for Coke Minimization in Dry Reforming of Methane

Mustu H., Arbag H., Yasyerli N., Yasyerli S., Yasyerli N., Yasyerli S., Dogu G., Dogu T., Dogu G., Dogu T., Gazi University, TR

Dry reforming of methane is a promising route for conversion of two of the most abundant greenhouse gases to syngas. Ni based catalysts are generally preferred due to low cost and good activity. However, significant [...]

Ionic Liquids for CO2 capture

Stiemke F., Iliev B., Adamová G., Schubert T.J.S., Romanos G., Kroon M., IOLITEC Ionic Liquids Technologies Inc., US

Since it is known that IL have the tendency to retain CO2 both physically (physical sorption) as well as chemically (chemisorption)[1], they can be used for the direct capture of CO2 replacing the current process [...]

Polyol–clay matrices with improved hydrophilic character and affinity towards CO2 – Attempts to CO2 concentration at room temperature

Nousir S., Ghomari K., Roy R., Azzouz A., University of Quebec at Montreal, CA

Polyol-clay matrices were prepared by incorporating various polyalcohols ranging from ethylene-glycol to bulky polyol dendrimers. Through thermal programmed desorption (TPD) revealed a significant enhancement of both the hydrophilic character and affinity towards CO2. The amounts [...]
