Consejo Superior de Investigaciones Científicas (CSIC), Instituto de Carboquímica (ICB). ( The “Combustion and Gasification” research group at ICB is composed by about 20 scientific researchers including staff, students and technicians. The group has a long expertise in gassolid reactions, reaction kinetics, modelling applied to fluidized bed combustion and gasification processes as well as on Chemical Looping Combustion (CLC) process. Since 2000 the Department is involved in the particle development, selection and testing of oxygen carriers for CLC, kinetic studies and reactor optimization for this process. They have participate in several EU projects related with CLC: GRACE(FP6), CCCC (RFCS), CLC GASPOWER(FP6), CACHET (FP6), UNIQUE(FP7), ACCLAIM(RFCS), and other Spanish research projects. CSIC has worked in the CLC Process to transfer the concept from laboratory to prototype scale carrying out a demonstration of the technology. Main achievements have been: 1) Development of oxygen carrier materials based on Cu and Ni suitable for the process, 2) Demonstration of the process concept at 10 kWth continuous CLC for 200 h working with Cubased oxygen carriers and 1000 h in a 500 Wth facility with Cu, Fe and Ni based oxygen carriers, 4) Testing of the effect of sulphur and light hydrocarbons in CLC, 5) Modelling of CLC for several gaseous and solid fuels (CH4, syngas, coal, etc.), 6) First demonstration of the CLOU technology for coal combustion in a 1 kWth continuous CLC plant.

Resources to be used in the project:

  • Thermogravimetric analyzers to determine reduction/oxidation reactivity of carriers.
  • Batch fluidized bed reactor setup with on line gas analysis.
  • Continuous 500 Wth unit for CLC with solid circulation control.
  • Facilities for carrier preparation by pelletizing and impregnation.
  • Facilities for oxygen carrier characterization i.e. physisorption, chemisorption, Hg porosimetry, TPR, XRD and SEM‐EDX.
  • Facilities for leaching tests.
