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...

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...

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...

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...

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...

Carbon Capture and Sequestration At the National Energy Technology Laboratory

Oct 16, 2011
John Litynski
Carbon, capture, and storage technologies are a promising option that can help reduce greenhouse gas emissions from industrial and power generation facilities while enhancing the energy security of the United States. The U.S. DOE National Energy Technology Laboratory is implementing the federal...

Synthesis of Novel Catalyst for the Trireforming of CO2-Rich Flue Gases

Mar 15, 2011
Tracy J. Benson
Today’s chemical industry is very complex with most commodity chemicals being produced from some variation of petroleum feedstocks. From transportation fuels to polymers, petroleum is truly the largest source of basic hydrocarbons for which many of the common household products consumers use. Along...

Scoping Study of Methanol Production From CO2 with Nuclear Electrolysis H2

Mar 15, 2011
Richard D. Doctor
A scoping study of system costs for producing methanol from CO 2 and H 2 using low-carbon electricity to supply the hydrogen from commercial electrolysis produced methanol via: CO 2 + 3H 2 ➝ CH 3 OH + H 2 O Assuming low-carbon electricity at $75/MW, electrolysis delivers hydrogen at $5/kg and the...
