Abstract

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.

测定双金属铜镍催化剂颗粒大小对水置换反应的影响的实验设计

以不同直径(0.2 cm、0.3 cm和0.4 cm)和长度(0.4 cm和0.6 cm)的圆柱形活性炭球为原料，以摩尔比2-1的比例合成了Cu-Ni双金属催化剂。在330°C和常压下的水气转换反应中对它们进行了评价。开发了一种实验设计来评估变量，颗粒直径和长度对一氧化碳转化的影响。通过方差分析(ANOVA)检验了主要因素的重要性及其相互作用。结果表明，球团直径和球团长度对一氧化碳转化率均有显著影响。催化活性结果表明，在粒径为0.2 cm、长度为0.6 cm的球团的最佳性能条件下，CO转化率可达96%。
