Dynamic Model of a Solar Thermal Transport Tube Reactor for Control Purposes

Nov 11, 2009
Elizabeth Saade
A solar thermal reactor receives concentrated solar irradiation and uses this energy to thermally convert biomass into synthesis gas (H2, CO and CO2). The operation of this reactor is affected by the presence of clouds, which act as a disturbance for this process. When clouds are partially covering...

Solar Thermal H2O Splitting Via Cobalt Ferrite Based Thermochemical Cycles

Nov 11, 2009
Jonathan Scheffe
Spinel ferrites of the form MxFe3-xO4, where M generally represents Ni, Zn, Co, Mn, Fe or other transition metals, have been shown to be capable of splitting water to produce H2 using solar energy according to the two step cycle shown below: MxFe3-xO4 xMO + (3-x)FeO + 0.5 O2 (1) xMO + (3-x)FeO +...
