摘要

目前的工作旨在通过缓慢热解方法研究基于mf的生物炭用于活性炭生产的潜力。通过不同浓度KOH的化学活化法，确定了AC产物的最佳工艺条件。以不同比例的KOH（1:2、1:3和1:4）浸渍油棕中果皮纤维（MF）生物炭，在800℃的温度下，以5℃/min的加热速率和1 L/min的氮气流量进行活化，保温时间为1 h。对于生物炭的表征，使用SEM-EDX对热解后的样品进行了研究。利用XRD和微拉曼光谱对制备样品的非晶相和晶体结构进行了表征。同时，利用BET、TGA和XPS对样品进行了表征。在此基础上，制备活性炭的最佳工艺参数为1:3的OPMF生物炭，该工艺获得了BET分析中最小孔径（2.67 nm）。采用紫外可见光谱法进一步研究了活性炭作为吸附剂的性能。结果表明，样品mfac2表现出最高的吸附率（68.07%），促进了OPMF作为低成本AC生产的潜力，从而最大限度地减少了处置管理问题。

A new and low-cost adsorbent material from mesocarp fibre char

The present work aims to investigate the potential of MF-based biochar via a slow pyrolysis method for activated carbon production. Through the method of chemical activation using various concentrations of KOH, the optimum condition of AC products was determined. Oil palm mesocarp fibre (MF) biochar impregnated with different ratios of KOH (1:2, 1:3, and 1:4) were subjected to activation at a temperature of 800 °C for 1 h holding time at 5 ^oC/min heating rate and with a nitrogen flow rate of 1 L/min. For biochar characterization, the pyrolyzed samples were investigated using SEM-EDX. To confirm the amorphous phase and crystalline structure of the prepared samples, XRD and micro-Raman spectroscopy were utilized. Meanwhile, the AC samples were characterized using BET, TGA analysis, and XPS. Herein, the optimum parameter for producing AC was presented by a 1:3 ratio of OPMF biochar which resulted in the lowest pore diameter (2.67 nm) in BET analysis. Further analysis was executed by UV–Vis spectroscopy to investigate the performance of AC products as adsorbent material. The result shows that the sample MFAC-2 demonstrated the highest rate of adsorption (68.07 %) which promoted the potential of OPMF usage as a low-cost AC production consequently minimizing the disposal management issues.
