The goal of this project is to identify and develop standards and measurement methods currently needed by the energy industry to enable the development of cost efficient carbon mitigation technologies. The project aims to develop standard reference materials (SRM™) as well as construct a physico chemical property/performance database for a variety of sorbent materials that will help industry define the specific properties that play a major role in CO2 adsorption and regeneration. In addition, the project will address current measurement challenges in the evaluation of critical properties of membranes and sorbent materials.
Identification of standards and measurements needed in the carbon capture industry, and the subsequent construction of a carbon mitigation road map, will be accomplished in collaboration with leaders in the field. Outreach activities such as workshops and seminars will be an integral part of the program. Materials considered as potential candidates for SRMs will be tested through a comprehensive evaluation process. A reference property and performance database of the physicochemical characteristics of the sorbent materials and their CO2 sorption performance will provide industry with reliable information for the rational design of sorbents and their processing methods. State-of-the-art analytical tools will be integrated, and measurement methods developed for determining properties that are currently difficult to obtain or verify. Some of the techniques under development will enable the determination of pore architecture and “closed” porosity, in-situ monitoring of the structural response on CO2 sorption in the presence of competing gases, and identification and location of atomic adsorption sites and adsorbate species.
Impact and Customers:
Activities in the carbon mitigation project will address current needs for standards and measurements in the area of membranes and solid sorbents for CO2 separation and capture applications. A new laboratory is being built for assessing the performance of CO2 sorbent materials based on capacity, kinetics, thermodynamics, life cycle, and selectivity. Equipment will include a high pressure thermogravimetric analyzer (TGA) integrated with an evolved gas analyzer (EGA) and a high pressure differential scanning calorimeter. In addition, high sensitivity volumetric measurements will be made using a custom-built, computer-controlled Sieverts apparatus.
