Tóm tắt

Chemical Looping Combustion (CLC) has the potential to efficiently capture CO2 from the combustion of fossil fuels at an affordable price. CLC is a process that produces a flue gas primarily consisting of CO2 and H2O. The CO2 can be easily separated and captured by condensing the H2O, similar to an oxy-fuel process. Although the process looks promising on paper, the challenge of making chemical looping a reality involves demonstrating that the process is technically feasible. To help achieve this goal, the U.S. Department of Energy?s (DOE) National Energy Technology Laboratory (NETL), has constructed and tested a 50kWth chemical looping reactor (CLR). The general arrangement of the process consists of a bubbling fluidized bed fuel reactor and a fluidized bed/riser air reactor. This paper will describe the results from a hematite ore that has been tested during a week-long test campaign.
