The Study of Hydrothermal Carbonization and Activation Factors' Effect on Mesoporous Activated Carbon Production From Sargassum sp. Using a Multilevel Factorial Design

Seaweeds are large-scale multicellular marine algae categorized based on color as Chlorophyceae, Rhodophyceae, and Phaeophyceae. No information has been provided the conditions affecting production of mesoporous activated carbon from one member described aquatic plants, namely Sargassum sp. Therefore, this study aimed to determine impact main factors their interactions sp.-derived manufactured (SAC) by hydrothermal carbonization CO2 activation methods. A mathematical approach was employed using a multilevel factorial design with being activator type (ZnCl2, CaCl2, & KOH), temperature (200, 225, 250oC), ratios (2 4). Meanwhile, response variables were yield BET surface area (SBET) SAC. Morphological, functional, crystallographic, porosity characterization carried out samples. The SAC-Ca-200-2 sample had highest yield, value 26.5 percent weight. activators having specific SAC-Zn-250-4, SAC-Ca-225-2, SAC-K-250-2, 1552, 1368, 1799 m2/g, respectively. pore size distribution in SAC products ranged 2.16 10 nm diameter. analysis conducted indicated interaction its ratio substantially impacted value; besides, only affects formation high pores.
