Central composite design

In this study, the objective was to employ experimental design in order to optimize the efficiency of diesel oil removal from water using activated carbon sourced from rambutan peel. A central composite design was utilized to investigate the impact of contact time, adsorbent dosage, initial oil concentration, and pH on both the removal efficiency and oil adsorption capacity across 30 different experimental designs.

Response surface methodology was applied to optimize the extraction of phenolic compounds from fresh Pouzolzia zeylanica plant using hot water as a solvent. A central composite design (CCD) in form (23+star) was used to investigate the effects of two independent variables, namely, extraction temperature (70 to 90oC) and extraction time (20 to 40 min).

This study aimed to optimize additional carrier concentration for spray drying of Pouzolzia zeylanica extract. Response Surface Methodology (RSM) with central composite design (CCD) was applied for optimization and investigation of the influence of maltodextrin (5ö15%, w/v) and carrageenan gum (0.06ö1.0%, w/v) concentration on the physicochemical characteristics of spray dried powder (bioactive compounds, moisture content as well as particle size distribution).

This paper presents the benzene alkylation with ethanol catalysed on the Y and ZSM-5 zeolite. The experimental results have shown that 30%H-ZSM-5/HY sample is the best for forming ethylbenzene. On this sample the reaction has been carried out by central composite orthogone design at the second level for three factors reaction temperature, flow speed and the molar ratio of ethanol/benzene. The target function for the productivity of ethylbenzene has been yielded. By checking the experimental and mathematic results we observed that current equation is suitable.
