The carbonisation-activation system was developed to produce activated carbon from oil palm kernel shell (OPKS). The OPKS was carbonised at 500C for 3 hr in an electric vertical reactor followed by steaming at 700C for another 3 hr in the same reactor. The process showed significant results with a high activated carbon yield of 32 high fixed carbon content of 88.6 with Brunauer-Emmett-Teller (BET) surface area of 305.67 m2 g-1. The OPKS-activated carbon was further tested to remove methylene blue. It could adsorb up to 99.7 of methylene blue using only 0.6 g litre-1 dosage of OPKS-activated carbon for 24 hr of treatment time. The results have been correlated in the Freundlich isotherm which was well fitted to the experimental data over the methylene blue experimental concentration range with correlation coefficients of R20.992.

Abstract

The carbonisation-activation system was developed to produce activated carbon from oil palm kernel shell (OPKS). The OPKS was carbonised at 500C for 3 hr in an electric vertical reactor followed by steaming at 700C for another 3 hr in the same reactor. The process showed significant results with a high activated carbon yield of 32 high fixed carbon content of 88.6 with Brunauer-Emmett-Teller (BET) surface area of 305.67 m2 g-1. The OPKS-activated carbon was further tested to remove methylene blue. It could adsorb up to 99.7 of methylene blue using only 0.6 g litre-1 dosage of OPKS-activated carbon for 24 hr of treatment time. The results have been correlated in the Freundlich isotherm which was well fitted to the experimental data over the methylene blue experimental concentration range with correlation coefficients of R20.992.
