Pitt engineers find CO2 carbon capture materials for coal-fired News


Christopher Wilmer, assistant lecturer at the Department of Chemistry and Petroleum Engineering, is co-sponsored by Jan Steckel Co-Investigator, led by AECOM's National Energy Energy Laboratory and AECOM based in Pittsburgh. Royal Chemistry of the Journal of Energy and Environmental Sciences: "Filtering a high cost method for calculating the carbon capture cost through mixed arrays".

"Polymers have been used for decades to filter and clean materials, but they are limited to the use of CCS," said Dr. Wilmer, Director of the Material Materials Laboratory at Swanson School.

"Mixed mixed matrixes, small particles dispersed in material and non-particles polymeric membranes, show their distribution and permeability properties, but the potential polymers and inorganic particles are very significant, so carbon capture is the best combination It can be tough. "


Dr. Wilmer says that the researchers are based on a wide-ranging study of metal and organic frames (MOF), porous glassware related to self-inorganic metal with organic bonds. These MFFs can store larger volumes than traditional tanks, which are very versatile and can be made with people with specific and specific properties.

Dr. Wilmer and his team have mixed a million matrices. Then, according to the data announced, they compared the permeability of each gas filter in each material and were evaluated based on three stages capture processes. Flow rate, catch fraction, pressure and temperature conditions were optimized for the functionality of membrane properties to identify the specific matrix produced by the carbon capture cost.

According to the United States Energy Information Administration, United States coal-powered power plants now represent only 30% of the nation's energy portfolio. In 2017, the largest share of 1,207 million tonnes CO2, or 69% of the total CO of energy in the United States2 US electricity sector emissions.

"Our computational models of hypothetical and real MOF have created a new database of over one million matrix mixed with the corresponding CO2 catch performance and associated costs, "said Dr. Wilmer.

"Advanced techno-economic analyzes resulted in 1,153 mixed matrix combinations, with the cost of carbon capture less than $ 50 per ton, thus creating an economically inexpensive and efficient way for the CO2 the capture of coal-fired power stations all over the world and the effective treatment of the significant source of fossil fuels CO2 in the atmosphere ".
