Mb Adsorption

In this research, it has been performed carbon activation of oil palm shells (CAC) prepared by chemical treatment as adsorbents of phenol and methylene blue (MB) in solution either in the form of single or in pair solution. The activation of carbon from the oil palm shells was done physically at a temperature of 700°C for 1 hour continued with chemical activation using 10% H3PO4 for 24 hours. Identification of functional groups on the carbon from oil palm shell before and after chemically activated was performed using infrared spectrophotometer (IR) and analysis of its surface morphology was carried out using scanning electron microscope (SEM). The phenol and MB adsorption process was performed in single and binary systems using the batch method. The adsorption of phenol on CAC is optimum at pH 8 while MB at pH 11 with optimum contact time of 90 min for phenol and 120 min for MB respectively. The phenol and MB adsorption data on the CAC in the single system follow the pseudo-second-order kinetics model with the adsorption rate constant of 0.399 and 0.769 g mmol-1 min-1 respectively. The adsorption isotherms of phenol and MB in CAC tend to follow Freundlich adsorption isotherm pattern with the adsorption intensity factor (n) for phenol, MB, phenol/MB, and MB/phenol: 1.739, 1.341, 1.334, and 1.293 respectively. The adsorbent of CAC is effective to remove phenol and MB in solution, either in single or paired condition.

Oil Palm Shell

Malaysia has been acknowledged as one of the largest producer and exporter in the production of oil palm biomass. This is not surprisingly that industry contributes massive amount of the waste such as empty fruit bunches, palm mesocarpfibre, and palm kernel shell. This abundance of oil palm by-products make them an attractive source of raw material for the production of activated carbon. The activated carbon has been widely used in variety industries such as bio-catalyst, removal of toxic substance, purification of liquid and gas as well as catalyst support. The comparison of characteristic of oil palm activated carbon produced via microwave and conventional heating has been discussed in this paper. The characterization of the activated carbon includes elemental analysis, the Brunauer-Emmet-Teller (BET) surface area as well as Scanning Electron Microscopy (SEM) has been analyzed in this study.Hence, from the result, it shows that the SEM micrograph of oil palm shell (OPS) activated carbon prepared via microwave heating by using chemical activation produced the clearly and uniformly pore compared to full cavity and not well formed of pore in oil palm shell (OPS) activated carbon via conventional heating.

Oil palm shell is one of biomass-wastes which is abundantly found in palm oil industries. Its economical value can be enhanced by converting it into hydrochar using a hydrothermal carbonization process (HTC). In this study, preparation of oil palm shell hydrochar was performed and the material was used as adsorbent to remove methylene blue from waste water. Effects of HTC temperature, KOH activator concentration, and adsorption time were studied. Functional groups of hydrochar were evaluated by Fourier transform infrared (FTIR) spectroscopy. Meanwhile, the uptake capacity of hydrochar to adsorp methylene blue was measured by using UV-Vis spectrophotometer. The results showed that dehydration and decarboxylation reactions took place more progressively at the higher temperature of HTC. It was also found that activation process resulted higher removal efficiency of methylene blue. The highest adsorption capacity (16.58 mg/g, with removal efficiency 99.51%) was obtained by hydrochar prepared by HTC 270°C, KOH 1.5 N, and carried out for 80 minutes.Keywords: activator; adsorption; hydrothermal carbonization; methylene blue; oil palm shellA B S T R A KTempurung kelapa sawit merupakan salah satu limbah biomassa yang jumlahnya cukup melimpah di industri minyak kelapa sawit. Nilai ekonomi tempurung kelapa sawit dapat ditingkatkan, salah satunya melalui hydrothermal carbonization process (HTC). Dalam penelitian ini, hydrochar dari tempurung kelapa sawit dibuat dan digunakan sebagai adsorben untuk menjerap metilen biru dari limbah cair. Dalam hal ini, akan dipelajari pengaruh suhu HTC, konsentrasi aktivator KOH, dan durasi adsorpsi. Gugus fungsional hydrochar dianalisis dengan FT-IR spectroscopy, sementara itu kapasitas adsorpsi terhadap metilen biru diukur dengan spektrofotometer UV-Vis. Hasil percobaan menunjukkan bahwa reaksi dehidrasi dan dekarboksilasi pada kondisi hidrotermal terjadi lebih cepat pada suhu HTC yang lebih tinggi. Selain itu, proses aktivasi dengan KOH terbukti dapat meningkatkan efisiensi penyisihan metilen biru. Kapasitas adsorpsi maksimum sebesar 16,58 mg/g (dengan efisiensi penyisihan 99,51%) dihasilkan dari adsorpsi dengan menggunakan hydrochar yang diperoleh dari HTC suhu 270 °C, diaktivasi dengan KOH 1,5 N dan durasi adsorpsi selama 80 menit.Kata kunci: adsorpsi; aktivator; karbonisasi hidrotermal; metilen biru; tempurung kelapa sawit
