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...

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...

Research On Enzyme-Catalyzed Sequential Reduction of Carbon Dioxide

Oct 18, 2011
Wenfang Liu
Enzyme-catalyzed reduction of CO2 will not only help to lessen greenhouse effect, but also to obtain valuable chemicals. The sequential reduction of CO2 to methanol under mild reaction conditions has been reported to be feasible by using sol-gel encapsulated or nanoparticle-attached dehydragenases...

Novel Electrochemical Process for Capture of CO2 From Power Plant Flue Gas

Oct 18, 2011
Saurav Datta
Energy efficient capture of CO 2 released from coal based power plants is a major challenge to reduce greenhouse gas emissions. The existing commercial technologies require substantial energy inputs in the form of heat and vacuum which leads to around 30 % parasitic energy loss. To overcome this...

Comparison of Amine-Based Absorbents for Post-Combustion Carbon Capture

Oct 18, 2011
Sumedh S. Warudkar
As a part of this work, we have performed a comparison of 4 amine-based absorbents using the process simulation software ProMax ® with TSWEET ® . Absorbents were compared at pulverized coal fired power plant flue gas conditions. The criteria for comparison of absorbents are the energy requirement...

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...

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...

Imidazole and Imidazole-Amine Hybrid Solvents for CO2 Capture

Oct 18, 2011
Jason E. Bara
Imidazoles and imidazole-amine hybrids are unique classes of organic solvents that feature properties similar to aqueous amine solvents and ionic liquids (ILs), both of which have received a great deal of attention for CO2 capture applications. However, to date, the utility of the imidazole...

Kinetics Study of Calcium Carbonate Decomposition At High CO2 Environment

Oct 17, 2011
Jian Zhang, Yong Min
With the concerns of “global warming”, CO2 sequestration from cement industry are becoming significant important for the “green processing” for the environments. This is because the cement processing released about 36% of CO2 comparing to the 12% from regular coal-power plant. CaO/CaCO3, a major...

Completing the Cycle: Capturing Gaseous Waste Carbon As Fuel/Chemicals

Oct 17, 2011
Michael A. Schultz
The world currently faces an enormous energy challenge. LanzaTech responds to this challenge by capturing and beneficially reusing waste carbon to make low carbon fuels and chemicals. The International Energy Outlook, in its 2010 reference case, projects that world primary energy consumption will...
