Sequential design of experiments was employed on optimization of MOF-235 synthesis for acetylene adsorption process. Two experimental designs were applied: firstly, a 2-level factorial design for screening and a central composite design one of response surface methodology (RSM). In this study, 23 factorial design of experiment was used to evaluate the effect of parameters of synthesis temperature, synthesis time and mixing speed on crystallinity of MOF-235. Experiments were conducted with 16 runs as per MINITAB 19 design software using MOF-235 synthesis. Half-Normal, Pareto, Residual, Main and Interaction effects were drawn based on the XRD results. The Analysis of Variance (ANOVA) of test results depict that the synthesis temperature and time have significant effect on crystallinity of MOF-235 (response variable). After screening, central composite design, was performed to optimize acetylene adsorption capacity of MOF-235 based on the synthesis conditions. |
