Análise termoquímica de reformador de etanol: produção de hidrogênio para acionamento de uma célula combustível do tipo PEM de 1 KW

摘要: This work presents Thermochemical analysis, based on the study of several parameters associated to steam reforming system, for dimensioning two ethanol reformers with enough capacity hydrogen produce operating a PEMFC (Proton Exchange Membrane Fuel Cell) 1 kW. In analysis system operation conditions studied, they were influences temperature and pressure in composition balance reactants, products types catalysts system. It was studied catalytic reactions reformer concentrations present gases flow synthesis water-gas shift reactor, which removes part CO it additional production process. stage conditions, amounts necessary The determination accomplished through methods gas chromatography analysis. results obtained first “prototype I”, used final II”. can be concluded that use hydrogen, is technically feasible, process consists route important obtaining “bio-hydrogen” alternative renewable energy raw material input country.
