DESCRIPTION:On behalf of Professor Jeff Bergthorson\, the Alternative Fuels
  Lab (AFL) at 91ÉçÇø invites you to a free talk by Aldo Steinfe
 ld (ETH Zurich) Seminar Abstract:\n\nThe entire production chain for renew
 able kerosene obtained directly from sunlight\, H2O\, and CO2 has been exp
 erimentally demonstrated. The key component of the production process is a
  high-temperature solar reactor containing a reticulated porous ceramic (R
 PC) structure made of ceria\, which enables the splitting of H2O and CO2 v
 ia a 2-step thermochemical redox cycle. In the 1st endothermic reduction s
 tep\, ceria is thermally reduced using concentrated solar radiation as the
  energy source of process heat. In the 2nd exothermic oxidation step\, non
 stoichiometric ceria reacts with H2O and CO2 to form H2 and CO – syngas – 
 which is finally converted into kerosene by the Fischer-Tropsch process. T
 he RPC features dual-scale porosity for enhanced heat and mass transfer: m
 m-size pores for volumetric radiation absorption during the reduction step
  and µm-size pores within its struts for fast kinetics during the oxidatio
 n step. We report on the engineering design of the 4 kW solar reactor and 
 the experimental demonstration of 290 consecutive redox cycles for produci
 ng high-quality syngas suitable for the processing of liquid hydrocarbon f
 uels. We further evaluate alternative materials\, e.g. doped ceria and per
 ovskites\, for improved redox performance.\n\n \n\n \n\n \n
