“…We use analysis of variance to examine whether there is a significant effect of the independent variable on the mass catalyst product of the catalyst or not. RSM analysis was carried out in full quadratic to reveal the interaction of each and combined variables [18]. The P value becomes the indicator of the significant effect from the independent variable to the dependent variable.…”

“…Response Surface Methodology (RSM) was used to correlate the independent variables including Mg/Al molar ratio and precipitation time to the dependent variables such as the mass catalyst product, conversion, yield, and selectivity of the isomerization process [18]. Moreover, the range of Mg/Al molar ratio is 1:1 to 1:4, while the precipitation time was 720-1080 min.…”

The substitution of Mg/Al hydrotalcite catalyst over the glucose-isomerase is expected to decrease the space-time and reduce the energy consumption of glucose isomerization into fructose. The quality of the Mg/Al hydrotalcite catalyst is determined during the synthesis process. The synthesis has been carried out in the various Mg/Al molar ratio and precipitation times and observed the catalytic activity in the isomerization. Response Surface Methodology (RSM) is used to analyze statistically the optimum condition of the synthesis process. The Mg/Al molar ratio was 1:1 to 4:1 with a precipitation time of 720-1080 min. The characterization of the Mg/Al hydrotalcite catalyst includes the functional groups of the constituent compounds by FTIR, the crystallinity and particle size by (XRD), and the surface area of the catalyst by BET. The RSM results show the optimum condition of the Mg/Al molar ratio and precipitation time to produce the highest mass catalyst product of Mg/Al hydrotalcite catalyst (3,38 g) is 3.34:1 and 984.85 min. The highest degree of crystallinity obtained is 28.70% with the particle size is 10.19 Å. The highest yield and selectivity of the isomerization process are 56.95% and 91.89%, respectively. By the RSM analytical method, the Mg/Al molar ratio and the precipitation time used in this catalyst synthesis do not give a significant effect on the catalytic activity of the isomerization.

<p>The purpose of this research was to evaluate the effectiveness of low-cost adsorbents for the removal of MTBE by employing natural kaolin clay with surface modification by KOH. The feasibility of MTBE examination by High Pressure Liquid Chromatography (HPLC) in aqueous solution was investigated. To get rid of impurities, the kaolin clay goes through a beneficiated process. Then, the thermal procedure was carried out at 990°C to prepare the adsorbent. XRD, SEM, and FTIR were used to characterize the geochemical and surface characteristics of the kaolin adsorbent. Basic operation parameters were evaluated in the batch experiment, including beginning MTBE concentrations, pH, contact time, and adsorbent dosage. For three different sized columns that were 12cm, 8cm, and 4cm, respectively, the percentage removal efficiency for MTBE was recorded as 97.79%, 99.08%, and 98.13%. This study demonstrated that the adsorbent's contact time and retention period are crucial for the elimination of MTBE, as demonstrated by the Thomas model and Thomson model with R2 values of 97.81, 99.21, and 98.36.</p>

a ceramic brick was obtained on the basis of waste from the fuel and energy complex: waste of combustible shale -inter-shale clay used as a clay binder and ash-slag material used as a thinning agent and a burnout additive, without the use of natural traditional materials. the linear regression method was used to optimize the composition of ceramic masses and construct model graphs based on the physical and mechanical properties of bricks. the analysis of model graphs is useful both for clarifying the ranges of the state between experiments and for predicting results that were not included in the experiment.
