Modeling of CO conversion in the Fischer–Tropsch synthesis using Co-Ru/CNTs catalyst

In this study, carbon nanotubes (CNTs) supported Cobalt-Ruthenium(Co-Ru)catalyst was synthesized using chemical reduction method. Inorder to display the effective parameters on CO conversion, two factorial design method was used. By considering temperature (T), pressure (P), Space Velocity (SV) and H2/CO ratio as the effective factors, different runs were designed for experiments. Quadratic model for CO conversion was derived according to the experimental results. To evaluate the accuracy of the obtained model, the analysis of variance (ANOVA) was applied as a important tool. With a 95% confidence limit, the ANOVA results indicated that the derived model is significant. Furthermore, the important effective parameters were expressed for CO conversion and the interaction of parameters was investigated as well. The results show that temperature is the most important factor on CO conversion while pressure interaction with H2/CO ratio is more effective than other parameter interactions.
