Estudio comparativo del rendimiento de la producción de bioetanol mediante métodos de extracción de primera y segunda generación a partir de la caña de azúcar (Saccharum officinarum).

Abstract

The present investigation, under the preliminary project format, developed the scientific processes necessary to structure a comparative study between the yields of first and second generation ethanol using sugar cane (Saccharum Officinarum) as raw material. The proposed methodology is of the quantitative type, with experimental design and located at the descriptive and exploratory level, the proposal has the purpose of fulfilling the objectives and the general hypothesis raised. Once the first and second generation bioethanol production processes have been described, the processes and laboratory tests necessary for the production and evaluation of the yields are presented. The results obtained in the laboratory tests allowed to demonstrate that the first generation ethanol using sugar cane juice obtained a higher yield of around 45% compared to the yield obtained by the cane bagasse as biomass for the production of second generation bioethanol , and it can be mentioned that regarding the production costs of the second generation biofuel (sugarcane bagasse) it is 4 more expensive than the first generation one (sugarcane juice). Among the recommendations it is considered to propose to the state the application of incentives for the research and development of second generation biofuels due to the benefits obtained in the protection of the environment and they do not represent a competition for food supplies.
