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...

Supercritical CO2 Extraction for Algal Biodiesel Production

Oct 18, 2011
Prafulla Dinkarrao Patil
SC-CO2 is cleaner green technology for extraction of algal lipids/oils for algal biodiesel production. This work offers an optimized method for the direct conversion (One-step) of algal biomass to biodiesel using supercritical CO 2 extraction and supercritical methanol transesterification. SC-CO 2...

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...

Torrefaction of Switchgrass As a Pretreatment for Catalytic Upgrading of Pyrolysis

Oct 18, 2011
Lance Lobban
The objective of this work is to use thermal pretreatment to separate the complex bio-oil mixture to produce less complex vapor streams of products from 1. light oxygenates (small aldehydes, acids) , 2. furan derivatives, and 3. phenolics. The selective production of products by thermal treatment...

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...

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...

New Design for Advanced Zero Emission Power Plant Concept

Oct 18, 2011
Wei Chen
The most significant anthropogenic greenhouse gas is CO 2 , which arises mainly from the use of fossil fuels. A new technology called Advanced Zero Emission Power Plant (AZEP) targeting CO 2 capture and storage (CCS) is being developed. In the AZEP concept, CO 2 -diluted O 2 is used to combust the...

Development of a Compact Fischer Tropsch Reactor

Oct 18, 2011
Lyman Frost
Fischer Tropsch (FT) synthesis is a polymerization process where a CH X species is added to a growing aliphatic chain. There are several models of the catalytic chain propagation rate and the termination of the chain growth (e.g. Anderson – Schulz – Flory model). The exact methodology for the...
