Title:
BEAM-DOWN SOLAR-THERMOCHEMICAL REACTOR FOR THE ULTRA-HIGH TEMPERATURE DISSOCIATION OF SOLID-OXIDES AND CREATION OF SOLAR FUELS AND MATERIALS AND METHODS OF USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2012/083097
Kind Code:
A3
Abstract:
A cavity reaction chamber including a reaction surface in the shape of an inverted cone and having a top and a bottom. Powder supply containers supply a layer of powdered reactant to the reaction surface. A beam of incident radiation diverges onto the reaction surface. A gas outlet receives gas exiting the reaction chamber. In semi-continuous operation, the reactor further includes an annular solids outlet, surrounding the gas outlet and positioned to collect solids exiting the reaction chamber. The reactor may be used in a process for producing solar fuels and solar materials, for example, by concentrating sunlight as incident radiation, feeding ZnO as the powdered reactant, collecting dissociated Zn and O2 as gaseous products, cooling gaseous products to precipitate solid Zn particles, reacting collected Zn particles with H2O to create ZnO and H2, recycling resulting ZnO into the feed stream, and capturing the H2 and/or the O2.
