Preparation of porous carbon from date palm seeds and process optimization

Abstract: The agricultural wastes like date palm seeds to be a suitable precursor for the preparation of porous carbon has been explored in the present work, utilizing phosphoric acid as the activating agent. The experimental methods reported in literature were chosen with certain modification in order to simplify the process. The process optimization was performed using the popular response surface methodology adopting a Box-Behnken design. Process optimization was performed to maximize the porous carbon Brunauer-Emmet… Show more

“…The highest BB9 percent adsorption was observed when both impregnation ratio and activation temperature had the highest values within the studied range. A similar observation of an increase in BB9 removal with an increase in activation temperature and impregnation ratio has been reported elsewhere [16].…”

“…The significance of a process or experimental factor is determined by the values of Fisher's F-test (F) and Prob > F (p). A larger value of F and a smaller the value of p, indicate that a factor is more significant [16]. "p" values less than 0.05, demonstrates that the influence of the corresponding factor on the response is statistically significant.…”

“…The commonly used chemical activating agents are H 3 PO 4 , KOH and ZnCl 2 . Phosphoric acid (H 3 PO 4 ) as a chemical activating agent has become popular since it is environment friendly and can be easily removed during washing of AC (Reddy et al 2015). One-step chemical activation is distinctly different from two-step activation since it requires single heat treatment, wherein the carbonization and activation occur simultaneously.…”

“…Por outro lado, temperatura muito baixas, pode não ocorrer um aumento satisfatório de quantidade de poros reduzindo a capacidade de adsorção (PEREIRA et al, 2008). Reddy et al, (2015) otimizou o processo de ativação por meio da metodologia de superfície de resposta e os pontos ótimos de suas análises foram 500ºC; razão de ativante 3,1 e o 71,4 min resultando em 445,7 mg/g de capacidade de adsorção e em uma área superficial de 846,7 m 2 /g.…”
