Abstract

Abstract: Regeneration of spent activated carbon for the refinement of injection by microwave heating was mainly studied using response surface methodology for optimal design and analysis. The effects of three regeneration variables, including regeneration temperature, regeneration time and material thickness, on the adsorption properties and yield of activated carbon were investigated with the analysis of variance (ANOVA), and the significant factors on each experimental design response were identified．The optimal condition has been identified to be the regeneration temperature of 700℃, regeneration time of 18 min and material thickness of 20mm. Under above condition, methylene blue adsorption value and yield of activated carbon are 187.5 mg/g and 65.20%, respectively. Furthermore, the BET surface area, total pore volume and average pore diameter of regenerated activated carbon are 962m²/g, 1.02mL/g and 4.27nm respectively.

Key words: activated carbon, regeneration, response surface methodology, optimal design, methylene blue adsorption value, surface area
