Abstract

This proposal aims to design and build a cavity blackbody for thermochemical reactions using solar energy. The first step will be the literature review of the subject to model the chemical reactions involved and to scale out the cavity blackbody that will absorb the energy generated by a solar simulator. The next step will be the selection and the topological optimization of the catalyst used in the thermochemical reactions. In the final step, concentrations of H2 and CO in the syngas will be measured and data regarding temperature and radiation of the equipment. The advances of this project will be reported monthly to RCGI and FAPESP and published in international journals. The proposal has an objective the project and construction of a black body cavity for accomplish reactions thermo-chemical with the use of sunlight. The first step is the bibliographic review that will allow the moulding of thermical reactions, and predict constructive aspects of the black body cavity that will absorb the irradiated energy by the solar simulator. After that will be done the selection and topological optimizationby the catalyst to be used for the thermical reaction, lastly will be performed measurements related to H2 and CO2 concentration in the synthesis gas produced, as well as temperature and radiation measurements for equipment calibration. The progress achieved in this project will be delivered in the form of monthly reports to RCGI and FAPESP and articles that will be submitted to international magazines. (AU)
