“…Although there are rarely reports of plasma technology applications for OPF and PKS pyrolysis processes, there is potential for both to be reduced using this method because the lignocellulosic content is relatively the same as that of biomass in general. As an example, OPF consist of 51.5 wt.% cellulose, 25.64 wt.% hemicellulose, and 19.10 wt.% lignin [6] by lignocellulosic content; and of for about 47.11 wt.% C, 44.92 wt.% O, and 5.16 wt.% H by element content [7]. Some latest reports show that plasma technology can be applied on some biomass pyrolysis processes [8][9][10][11][12][13].…”

One of the oil palm tree’s solid waste is oil palm fronds. Due to its lignocellulosic composition, it has the potency to convert it into carbon. The common heat treatment method to convert oil palm fronds into carbon-based material is pyrolysis. However, this process has some disadvantages, such as being time-consuming and just producing amorphous carbon. Different from common pyrolysis temperatures, in this study we use a higher temperature (4000 °C) generated by DC current arc plasma. This process is faster than the common pyrolysis process (less than 10 minutes) and produces crystalline material. This product is then characterized by Raman spectroscopy, SAED-TEM, XRD, FT-IR, and SEM/EDX. Based on Raman spectroscopy, this crystalline material shows the characteristics of semiconductor carbon. Based on the SAED-TEM, there is a (002) plane of hexagonal crystal structure detected (graphite phase characteristics). An XRD analysis shows the characteristics of the trigonal crystal structure (P3) constructed by O and H atoms. An FT-IR characterization shows that there are C=C, C-H, and O-H bonds, while the EDX analysis result shows a carbon-to-oxygen ratio of about 4.23. Therefore, based on the whole interpretation, the plasma-assisted pyrolysis treatment is successfully used to convert oil palm fronds into reduced graphite oxide (rGO).

“…The cellulose content in palm fronds is 34.89%, hemicellulose 27.14% and lignin content is 19.87%. This cellulose is the highest quality cellulose which has the potential to be further processed to produce new products with high economic value, namely activated carbon (Ajayi et al, 2022;Said Azmi et al, 2023;Suherman et al, 2021).…”

One of the most common plantation biomass wastes is palm fronds, which will decompose without further processing. Lignin, hemicellulose, and cellulose contributed 31.7 percent, 33.9%, and 17.4%, respectively, of the chemical compounds found in oil palm leaves. The purpose of this study was to determine the ability of activated carbon to adsorb copper and lead metals, as well as to calculate its kinetics and adsorption capacity. Activated carbon with a certain amount is added to 50 ml of copper and lead metal solution for a certain time. The results obtained after the adsorption process were analyzed using Atomic Absorption Spectrophotometry (AAS). From the results of AAS analysis, it was found that activated carbon with a mass of 1.5 g and a contact time of adsorption for 40 minutes was the most effective in reducing the concentration of copper and lead metals. Copper metal adsorption follows Freundlich adsorption isotherm model while lead metal follows Langmuir adsorption isotherm model. The adsorption kinetics pattern of copper and lead metals follows second order kinetic adsorptions.
