This research is framed in the areas of alternative energy, thermodynamics and heat transfer.The aim was to develop a multizone gasifier and characterize the synthesis gas produced by it, using waste from the corn agroindustry as feed biomass, separating the combustion and gasification zones, with a view to coupling it to a dual biofuel-solar cooling system for the conservation of agro-industrial products in non-interconnected areas.It's divided into five parts; the first part consists in the determination of thermophysical properties of the corn cob.In the second part, the preliminary design of the multi-zone gasifier was developed.The third part consisted of performing five simulations in the Fluent software, to evaluate the temperature profiles.The fourth part was the multi-zone gasifier construction process.Finally, the fifth part used four tests obtained from the variation in the amount of mass present in the gasification zone, which are carried out to evaluate the thermal-energy properties of the synthesis gas that occurs in each test.The Lower Heating Values (LHV) obtained for each test were 1,981; 5,184; 4,214 and 2,026 MJ / kg respectively.The result obtained in test # 2 stands out, which compared to a gas obtained in a Downdraft gasifier for the same biomass, has an increase of 69,17%.Likewise, a higher mole fraction of methane in the synthesis gas stands out compared to that produced by other gasifiers.
