Thesis DISEÑO E IMPLEMENTACIÓN DE REACTOR PARA LA GENERACIÓN DE SYNGAS UTILIZANDO RADIACIÓN SOLAR DIRECTA CONCENTRADA PARA LA GASIFICACIÓN DE CARBONES MINERALES(Universidad Técnica Federico Santa María, 2016) Vicencio Covarrubias, Miguel Alejandro; TOLEDO TORRES, MARIO GONZALO (prof. guía); MENA YANSSEN RAFAEL GERARDO (Correferente)Under the project FONDAP “Solar Energy Research Center (SERC-Chile)”, the focus of this work is the experimental study of generation of syngas based on the gasification of coals. From this perspective, in order to make the generation of synthesis gas more attractive energy market, which aims to involve technologies that use non-conventional renewable energy, in this case solar energy. To develop this work, an analysis of the state of affairs is, as studies from the gasification of hydrocarbon are satisfactory for the production of hydrogen as a fuel gas from coal, which is a solid fuel. The research will be based on an analysis of the behavior of generation of syngas, with the addition of solar concentrators that will revolve around the hypothesis, with the main interest projections of coal as a clean fuel. As for the activities, a non-optimized pyrolytic reduction is performed on basis of a partial oxidation by applying heat from a source of solar energy is done concentration. Two experiences are contempled, one to 250 [g] of bituminous coal contained in a reactor transparent body and having a material transport system. As above, it is possible to generate a synthetic gas average volume fractions: 1,03% 2 H y 0,5% CO . Regarding the second experiment, the reactor is confined to a closed accommodation with intake air mass controlled variable coal. Test 50, 100 and 150 [g] of bituminous coal are performed with average volume fractions 2 H proced: 3,69%, 7,62% y 13,24% respectively. The results show that the solar thermal concentration array delivers enough heat to reduce solid hydrocarbon. While weather conditions are appropriate for the test period, it can be controlled oxygen levels in the reactor in order to enhance the synthetic gas concentrations.
