ICCI Abstract
As concerns about climate change escalate, emphasis is being placed on developing energy technologies that can efficiently process fossil fuels while separating CO2 for sequestration. Chemical looping combustion (CLC) is a leading low-CO2 technology that uses metal-based oxygen carriers in two interconnected fluidized beds to inherently separate oxygen in air from nitrogen, so that after reaction with a fuel such as coal, the product CO2 is concentrated in a form suitable for sequestration with minimal additional processing. Although researchers at several institutions around the world are studying chemical looping combustion, the technology is still relatively new and research has primarily been conducted at lab or bench scale. Under this program, the University of Utah will advance development of chemical looping combustion by finalizing construction of a 100 kWth, dual fluidized bed chemical looping combustion process development unit and performing initial evaluations of system performance when processing Illinois coal. The goal is to use measured data from the PDU to develop energy and material balances for the system, and to determine carbon conversion, carbon capture efficiency and CO2 purity. This will be achieved by preparing CLC oxygen carriers and operating the PDU with Illinois coal over a range of conditions and measuring system temperatures, flow rates and product gas compositions.
