The Box-Behnken algorithm based on the response surface methodology (RSM) was utilized to optimize plasma DRM process. The effects of process variables including MW power, CO2/CH4 ratio and total feed flow rate on produced syngas selectivities and syngas ratio (H2/CO) were studied by the Analysis of variance (ANOVA) method using three different models based on quadratic polynomial regression. Both experimental and optimized results confirmed the important paramount role of MW power on syngas selectivity compared to other investigated parameters. The CO selectivity and H2/CO ratio was considerably influenced by CO2/CH4 ratio while the effects of total feed flowrate on plasma DRM performance was insignificant. The interactions between the different variables had a weak effect on the H2 selectivity and ratio of H2/CO. At the maximum desirable value of 0.95, the optimum H2 and CO selectivities were 53.57% and 57.35 % with a H2/CO ratio of 0.9.}, keywords = {Box-Behnken Design,,,,،,؛CO2 reforming of methane optimization,,,,،,؛Microwave Plasma,,,,،,؛Syngas production}, url = {https://ijogr.uotechnology.edu.iq/article_15640.html}, eprint = {https://ijogr.uotechnology.edu.iq/article_15640_bd6ed110ed9db5470e811d9c65cee5ef.pdf} }
