Improving Gas Condensate Reservoir Productivity

Oct 18, 2011
Adel Elsharkawy
Gas condensate reservoirs experience great losses in productivity as the reservoir pressure drops below the dew point pressure due to formation and accumulation of liquid condensate around the well bore and subsequent reduction of gas relative permeability. Several methods have been proposed to...

Heterogeneous Catalysts in the Dehydration of Fructose to HMF

Oct 18, 2011
Sylvia Reiche
Several crucial steps in the upgrading of biomass-derived raw materials involve acid catalyzed reactions, such as the hydrolysis of cellulose or the dehydration of sugars. Although heterogeneous catalysts are desired in large scale industrial processes, their application is limited by several...

The Capture of Carbon Dioxide by Ionic Liquid

Oct 18, 2011
Hongyan He
Ionic liquid is one kind of organic salts with negligible volatile pressure which might lead to promising substitute candidates for alkanolamines in separation of carbon dioxide. To satisfy this requirement effectively, task specific ionic liquids with alkaline groups, such as imidazolium cation...

Reduction of Neptunium In Synthetic High Level Liquid Waste

Oct 18, 2011
Shaowei Li
High-level liquid waste (HLLW), which is produced from reprocessing of the spent nuclear fuel and contains actinides, 90Sr, 137Cs, 99Tc, 129I, etc., engenders permanent hazard to environment. The safe treatment and disposal of HLLW are crucial to sustainable development of nuclear energy. The TRPO...

Study of CaO Carbonation for CO2 Capture Process

Oct 18, 2011
Loïc Favergeon
Anthropogenic carbon dioxide (CO 2 ) emissions, major contributors to the greenhouse effect, are considered as the main cause of global warming. So, decrease of CO 2 emitted by large industrial combustion sources or power plants, is an important scientific goal. One of the approaches is based on CO...

Structural Characterization of AHP-Pretreated Biomass

Oct 18, 2011
Muyang Li
Alkaline hydrogen peroxide (AHP) pretreatment is exceptionally well-suited to grasses, yielding high digestibilities at low enzyme loadings, while generating relatively few fermentation innhibitors. For AHP pretreatment, the question of how structural and chemical compositional changes within the...

Phase-Changing Absorbents for CO2 Capture

Oct 18, 2011
Sarah Genovese
A process to capture CO 2 from flue gas using a liquid material that reacts rapidly with CO 2 to form a solid offers many advantages over conventional liquid-only CO 2 capture methods. The net CO 2 capacity of the system will be increased, the overall system size will be decreased, and the energy...

Realizing the Potential of Advanced Biofuels

Oct 18, 2011
Thomas Foust
Advanced biofuels or drop-in fuels is the terminology used to refer to hydrocarbon fuels that are direct replacements or supplements for existing gasoline, diesel and jet fuels currently refined from conventional petroleum feedstocks. Drop-in fuels from biomass will need to meet all of the refinery...

A-Priori Estimation of Reactive Amino Acid Based Ionic Liquids for CO2 Absorption

Oct 18, 2011
Johannes Voelkl
The separation of CO 2 is an important topic in thermal separation science. The scrubbing of carbon dioxide from exhaust gases has gained more interest in the last years to reduce the emissions of green for counteracting global warming but is also an important process step in biogas upgrade to...
