Se sintetizaron catalizadores bimetálicos de Cu-Ni en relación molar 2-1 en pellets cilíndricos de carbón activado de diferentes diámetros (0,2 cm; 0,3 cm y 0,4 cm) y longitud (0,4 cm y 0,6 cm); se evaluaron en la reacción de desplazamiento de agua a 330 °C y presión atmosférica. Se realizó un diseño experimental para evaluar el efecto de las variables, diámetro y longitud, sobre la conversión del monóxido de carbono. La importancia de los principales factores y sus interacciones se examinaron por medio del análisis de varianza (ANOVA). Los resultados mostraron que tanto el diámetro como la longitud afectan significativamente la conversión del monóxido de carbono. Los resultados de la actividad catalítica, bajo las mejores condiciones de diámetro (0,4 cm) y longitud (0,6 cm) de los pellets, mostraron una conversión del monóxido de carbono del 96%.

Bimetallic Cu-Ni catalysts were synthesized with molar ratio 2-1 in cylindrical activated carbon pellets of different diameters (0.2 cm, 0.3 cm, and 0.4 cm) and length (0.4 cm and 0.6 cm). They were evaluated in the water gas shift reaction at 330 °C and atmospheric pressure. An experimental design was developed to evaluate the effect of variables, diameter and length of the pellets, over carbon monoxide conversion. The importance of the main factors and their interactions were examined by analysis of variance (ANOVA). The results showed that both diameter and length of the pellets had significant effect on carbon monoxide conversion. The results of the catalytic activity indicated that up to 96% CO conversion was obtained at the optimum characteristic of the pellets, diameter of 0.2 cm and length of 0.6 cm.
Foram sintetizados catalisadores bimetálicos de Cu-Ni em proporção molar 2-1 sobre pastilhas de carvão ativado de diferentes diâmetros (0,2 cm; 0,3 cm e 0,4 cm) e comprimentos (0,4 cm e 0,6 cm) e foram avaliados na reação de mudança de vapor de agua a 330 °C e pressão atmosférica. Um desenho experimental foi desenvolvido para avaliar o efeito de variáveis, diâmetro e comprimento, na conversão de monóxido de carbono. A importância dos principais fatores e as suas interações foram examinados por análise de variância (ANOVA), os resultados mostraram que tanto o diâmetro e o comprimento afetam significativamente a conversão de monóxido de carbono. Os resultados da atividade catalítica com as melhores condições de diâmetro (0,4 cm) e o comprimento (0,6 cm) das pastilhas mostrou uma conversão de monóxido de carbono de 96%.
