Activated carbon from potassium hydroxide spent liquor lignin using phosphoric acid Academic Article

abstract

• Activated carbon was prepared by phosphoric acid (H3PO4) activation of potassium hydroxide (KOH) pulping spent liquor lignin from rice straw and compared with KOH hydroxide activation. The process parameters, such as impregnation ratio, activation temperature, and activation time were varied and their effects on the yield of activated carbon and iodine number were studied. The activated carbon prepared by H3PO4 at 800C for 60 min at an impregnation ratio of 2.5 reached a Brunauer-Emmett-Teller (BET) surface area of 1063 m2/g, including pore diameter of 14.4 nm, iodine number of 525 mg/g, and yield of 49.2%. Yield and BET surface area in KOH activation was much lower than that of H3PO4.
