“…The ethanol extracts by the soxhlet method were 3%, containing oil, waxes, fats, and resin, and they were comparable to a previous study (Fahma et al 2010). The α-cellulose content of the isolated OPEFB cellulose was 93.7%, which is comparable to the reported value of 97.1% (Leh et al 2008), but higher than 62.3% (Wanrosli et al 2011). Further delignification with performic acid effectively removed the lignin and the hemicelluloses fraction, and produced a total cellulose yield of 64% (w/w) on a dry weight basis, which was higher than the previously reported yield at 44.4% (Sun et al 1999) and 60.6% (Wanrosli et al 2004) using chlorite and sodium hydroxide, respectively.…”

Cellulosic fibers in Oil Palm Empty Fruit Bunches (OPEFB) are tightly packed with lignin, hemicelluloses, small depositions of wax, and inorganic elements. In the present work, eco-friendly reagents with low concentrations of 20% (v/v) formic acid and 10% (v/v) of 30% hydrogen peroxide were employed at 85 o C for the extraction of cellulose from OPEFB. The yield of 64% (w/w) achieved was among the highest ever reported. Based on the XRD, the -cellulose content was 93.7% with a high crystallinity of 69.9%. The average diameter was 13.5 μm with structural evidence of separated fibrils as investigated by FESEM. The TEM analysis suggested that the material was crystalline and its geometry was a monoclinic structure. The FTIR spectral peaks representing wax and hemicelluloses at 1735 cm -1 and 1375 cm -1 , respectively, and lignin at 1248 cm -1 and 1037 cm -1, were not observed in the extracted OPEFB-cellulose spectra. Based on the TGA results, thermal stability at 325 o C with a single degradation curve suggests the purity of OPEFB-cellulose.

“…This could be due to the caramelization of hemicellulose in water‐less solution (solvent ratio = 0.8) which end up as an insoluble residue in lignin analysis. Furthermore, it is reported that lignin tends to re‐condensate at elevated temperature . As a result, both hemicelluloses caramelization and lignin re‐condensation are complementary and in turn rendering in low lignin removal at eminent temperature and solvent ratio.…”

Four primary factors in controlling effectiveness of organosolvent pretreatment in lignin removal (%), cellulose retained (%), as well as hydrolysis (%) was done through a central composite design (CCD) coupled with response surface methodology (RSM). Statistically analysis predicted 54.49% of lignin removal, 86.40% of cellulose retained, and 90.67% of hydrolysis yield under numerically optimized process conditions (182.84 C, 0.61% solvent ratio, 0.69%w/w catalysts concentration, and 92.17 min reaction time). Almost reproducible results were successfully gained, suggesting feasible of design of experiment (DoE) in optimizing pressed pericarp fiber (PPF) pretreatment with nitric acid‐catalyzed ethanol solvent. Both the untreated and treated PPF were characterized by using scanning electron microscopy (SEM), X‐ray diffraction (XRD), and Fourier transformed infrared spectroscopy (FTIR). It was found that the treated PPF showed a distorted surface structure (SEM), amorphous and cellulose II pattern (XRD) and bonds shrinkage for several functional groups of lignin and hemicellulose while bands expanded for functional groups of cellulose (FTIR). © 2013 American Institute of Chemical Engineers Environ Prog, 33: 238–249, 2014

“…This pulping technique is regarded as environmentally friendly which fractionate raw materials and recover the lignin and water soluble components including organosolv solvent, leading to less water pollution [49]. Wanrosli et al [74] investigated the effect of pulping temperature, HCl catalyst, and acetic acid on OPF-pulp properties. Aforementioned investigations encouraged the Acetosolv pulping technique on OPF.…”

As the world second largest producer and exporter of palm oil after Indonesia, Malaysia's palm oil industries generate huge amount of biomass especially after pruning or harvesting the fresh bunch. The generated oil palm biomass includes empty fruit brunch (EFB), palm kernel shell, oil palm trunk (OPT), oil palm frond (OPF), palm oil mill effluent (POME), and mesocarp fiber. Among the generated oil palm biomass, OPF is by far the highest in quantity, accounting for more than 50% of the total biomass generated in the oil palm industries. Therefore, OPF appears to be a very promising source of raw materials in Malaysia. Considerable amount of researches have been carried out to investigate the nutritional value and economic viability of OPF and its suitability for reused as recycle energy, nutrients, or being transformed into value‐added end products. Thus, this article aims to present an overview on the current scenario in Malaysian's palm oil industries, covering topics on the availability and the characterization of OPF. This article also emphasizes on the superior recycling of OPF in various fields and major challenges in the utilization of OPF. Based on the findings presented, it is definitely clear that OPF has the potential to serve as sustainable and promising biomass source for Malaysia, not only to reduce the environmental problem caused by openly burnt or landfill disposal of OPF but also to generate extra revenue for the country. © 2017 American Institute of Chemical Engineers Environ Prog, 36: 1864–1874, 2017
