The Response Surface Methodology (RSM) has been applied to explore the thermal structure of the experimentally studied catalytic combustion of stabilized confined turbulent gaseous diffusion flames. The Pt/γAl 2 O 3 and Pd/γAl 2 O 3 disc burners were situated in the combustion domain and the experiments were performed under both fuel-rich and fuel-lean conditions at a modified equivalence (fuel/air) ratio (Ø) of 0.75 and 0.25 respectively. The thermal structure of these catalytic flames developed over the Pt and Pd disc burners were inspected via measuring the mean temperature profiles in the radial direction at different discrete axial locations along the flames. The RSM considers the effect of the two operating parameters explicitly (r), the radial distance from the center line of the flame, and (x), axial distance along the flame over the disc, on the measured temperature of the flames and finds the predicted maximum temperature and the corresponding process variables. Also the RSM has been employed to elucidate such effects in the three and two dimensions and displays the location of the predicted maximum temperature.

“…However, these methods have a lot of limitations for practical applications due to their complicated and expensive synthetic processes, harsh practical conditions, low resistance, and poor selectivity. Lately, electrospinning has been shown to be a popular and effective method for the production of the functional nanofibrous filter with diameter ranging from nanometer to micrometers . The fibrous structure has attracted specific attention in many practical applications among the different types of surface structure and roughness.…”

Three reusable and durable superhydrophobic nanofibrous filters were prepared by dip coating the nanofibrous fabric in the three different dispersed solutions of the newly modified nanoparticles (ZnO-NSPO, AlOO-NSPO, and titanium dioxide [TiO 2 ]-NSPO). The contact angle results proved that the TiO 2 -NSPO coated nanofibrous polyacrylonitrile (PAN) filter was hydrophobic with the water contact angle (WCA) of 141 while the ZnO-NSPO and AlOO-NSPO coated nanofibrous PAN filters were superhydrophobic with the WCA of 168 and 152 , respectively. The as-prepared filters can be utilized as an effective martial for oil-water separation with separation efficiency of over 98%.

Optimization of Dry Reforming of Methane over a Ni/MgO Catalyst Using Response Surface Methodology

et al. 2022

View full text Add to dashboard Cite

The Box‐Behnken experimental design method was applied to study optimization of dry reforming of methane over a magnesia‐supported nickel catalyst (Ni/MgO). The catalyst was prepared by impregnation method and characterized using Brunauer‐Emmett‐Teller analysis, X‐ray diffraction, thermogravimetric analysis, and transmission electron microscopy. Response surface methodology (RSM) modified by the Box‐Cox method was applied to investigate the effect of different operating parameters on conversion and formation of the different components of the reaction system. The RSM‐generated predictive models verified by analysis of variance were used to simulate the responses of the operating variables. This study revealed that the reaction temperature has the most pronounced effect followed by the CO2/CH4 mole ratio while the gas hourly space velocity had a negligible impact.
