Aprovechamiento del Bagazo Industrial de café como biomasa para la sustitución parcial de combustible

Abstract:

This study was developed with the purpose of adapting the industrial coffee bagasse as biomass and to produce briquettes to improve the application of these agroindustrial wastes like a renewable energy similar to a biofuel. Previously, a characterization of industrial bagasse coffee is made. The stages involved are drying, milling, screening and densification, to obtain a solid biofuel by the action of a vegetable binder gum with water, controlling the parameters established during the process. Finally, a comparison with fossil fuels and industrial bagasse used currently is performed. The biomass was subjected to different tests, highlighting the higher calorific value (31.55 MJ/kg) and ash content (4.86%), then calculations were carried out to estimate the percentage of partial substitution of the bunker by biomass, resulting in a 55%. Production tests were carried out, with different percentages of binder, the best results were obtained for a composition of 10% binder with 90% coffee bagasse. These briquettes were subjected to different tests, highlighting the humidity (1.13%) and higher calorific value (29.79 MJ/kg). Finally, a comparison with fossil fuels and industrial bagasse used currently is performed.
