Among the possible renewable energy sources, biomass was chosen as an alternative for study, which is the product and byproduct or residue that can be of forestry, agricultural, agro-industrial, animal production and urban waste origin. The chosen biomass was sugarcane bagasse, because in addition to being a renewable source, highly abundant in our country, capable of producing more than one input option such as alcohol, ethanol, etc., it is of interest in studies for a possible renewable energy source, emits little pollutant and during planting captures carbon dioxide, which is a greenhouse gas. The gasification process, which transforms solid fuel into a liquid phase or into combustible gas, was used for the production of gases and among them, the focus is on the quantification of hydrogen gas. For the analysis, the moisture content of sugarcane bagasse and the theoretical air content were varied. In relation to the moisture content present in the biomass, this will result in a reduction amount of H2 mass, which can create a relationship where, when the moisture content varies from 0 to 12,5%, the mass percentage variation is reduced by approximately 96%. The variation of theoretical air, from 0 to 0,065 moles, shows a variation in the molar percentage of hydrogen of more than 90%. Therefore, the proper determination of these two properties is of utmost importance.pt-BRAttribution-NonCommercial-NoDerivs 3.0 Brazilhttp://creativecommons.org/licenses/by-nc-nd/3.0/br/gás de efeito estufaemissão de poluentesbiomassacana-de-açúcargaseificaçãoumidadear teórico.bachelorThesis
