Resumo: The present work has the objective to evaluate the catalytic activity and the temperature profile inside an integral steam reforming fixed bed reactor heated by an electrical furnace and packed with an industrial catalyst. Nine temperature measures were made along nine axial positions and the composition of the products reaction were evaluated by gas chromatography. The experimental conditions were: temperatures furnace of 500ºC, 600ºC, and 700ºC, feed molar ratio [H2O/CH4] = 4, and mass flow rate of 0.2 and 0.5 kg/m2.s. The results show that the use of the nine points was enough to represent the thermal behavior of the reactor. Both the catalytic activity and the conversion depend of operational temperature. However, the fixed bed temperature is independent of mass flow rate at the used experimental conditions

Foram efetuadas medidas de temperatura no leito em nove posições axiais distintas e a composição dos produtos da reação foram determinadas por cromatografia. Os ensaios foram conduzidos com o forno a 500, 600 e 700ºC, razão molar de alimentação [H2O/CH4 ] = 4 e densidade fluxo-mássico de 0,2 e 0,5 kg/m2.s. Os resultados indicam que a utilização dos nove pontos foi suficiente para representar o comportamento térmico do reator e evidenciam a existência de perdas de calor significativas nas extremidades do reator. Tanto a atividade catalítica como a conversão apresentam-se sensíveis à temperatura operacional, entretanto, a temperatura do leito é praticamente insensível à vazão nas condições experimentais exploradasUniversidade Estadual De Maringá2008-03-27info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciTechnol/article/view/145510.4025/actascitechnol.v27i2.1455Acta Scientiarum.
