A novel Integrated Vacuum Carbonate Absorption Process (IVCAP) for post-combustion CO2 capture is being developed at the University of Illinois at Urbana-Champaign. A key technical aspect of this process is to employ a biocatalyst, carbonic anhydrase (CA...Read more
Absolute and per-capita energy consumption is bound to increase globally, leading to a projected increase in energy requirements of 50% by 2020. The primary source for providing a majority of the energy will continue to be fossil fuels. However, an array of enabling technologies needs to be...Read more
The nation is facing a renaissance in energy technology to include dramatic changes in transportation, electricity production, distribution and use, and energy efficiency. The nation is also rapidly expanding its scientific capabilities and is currently leading the world in areas such as...Read more
In this work, we will report a new liquid/inorganic membrane product concept for CO2 separation. A liquid fluid of selective CO2 absorption properties is immobilized in a thin, inorganic substrate sheet (20~50um) of graded pore structures. CO2 selectively absorbs into the liquid fluid in the...Read more
A monumental task for improving the feasibility of carbon capture from the flue gas of coal-fired power plants is reducing the total energy cost. A generic absorption/stripping process using an aqueous amine solvent would reduce the net power production of a coal-fired power plant by roughly 30...Read more
We will discuss a history of Industrial gas usage and how they helped shape the fuels and petrochemicals Industries. A look at the ftutre of IG in F&PD will also be presented.Read more
Production of power from coal inevitably generates carbon dioxide (CO2) as a by-product. To mitigate global climate change, this CO2 must be captured and sequestered. With current technologies, separating CO2 from flue gas accounts for about 70% of the total cost for CO2 capture and...Read more
We describe a new class of porous metal-adeninate crystalline materials. We describe the syntheses of these materials and discuss strategies for optimizing the capacity of these materials as selective sorbents for carbon dioxide. In particular, we describe how we can control the coordination...Read more
Global climate models indicate that acting rapidly to reduce carbon dioxide emissions will provide greater benefits to the environment than delaying action; however, new technologies, currently under development, may be significantly less costly than those currently ready to be deployed. This...Read more
The increase of atmospheric carbon dioxide concentrations in recent years is well documented. Its potential link to an earth wide greenhouse-like effect has led recently to tighter regulations on carbon dioxide emissions from various industrial sources. One of the most common emitters is the...Read more
Gasification of coal – a low-cost and abundant domestic feedstock – and subsequent conversion to hydrogen and energy with simultaneous CO2 capture can improve national energy security in an environmentally responsible manner. To fulfill the promise of clean energy production through gasification...Read more
Improved solvent reaction kinetics and carbon capacity continue to be a major research interest for the scrubbing of CO2 in post-combustion processes. The DOE has set a new target for post-combustion CO2 capture of less than a 35% increase in the cost of electricity, while capturing at least 90...Read more
In order to capture the carbon content of coal, one option would be to gasify it with mixtures of, e.g. steam, CO2 and O2, to produce synthesis gas: the water-gas shift (WGS) reaction, CO + H2O <--> CO2 + H2, could then be used to increase the yield of hydrogen. In principle, if the WGS...Read more
In the carbon capture and sequestration (CCS )scenario, vapor liquid equilibrium (VLE) curves represent the theoretical relationship between local gaseous CO2 vapor pressure and the respective carbon loading in solution for a given operating temperature. It determines the maximum carbon content...Read more
Secondary Effects of Reducing Carbon Dioxide Emissions
While climate change has lost some interest to the global economy, the United States and the World continue to move forward on advancing research and technologies to capture, sequester, or reuse the green house gas carbon

Coal has performed an important role as the primary energy source since the industrial era in the eighteenth century. Recently, the importance of coal has been growing in the world. In fact, IEO2010 reports that energy consumption of coal is growing from 132 quadrillion...Read more
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...Read more
The climate implications of emerging technologies that capture CO2 to produce transportation fuels (CCTF) are investigated by studying two examples: biodiesel from microalgae and Sandia National Laboratory’s S2P process. Simple performance and economic models for each...Read more
Complimentary Theoretical and Experimental Studies: CO2 Capture with Supported Ionic Liquid Membrane
Introduction
Fossil fuels supply a majority of the world's energy needs. However, the combustion of fossil fuels is one of the major sources of the greenhouse gas CO2. Integrated gasification combined cycle (IGCC) is one the most efficient
