Pyrolysis of oil palm biomass residue can convert the rich organic matter in biomass into sustainable green energy, thereby addressing the challenge of surplus oil palm biomass residue generated during cultivation. Nonetheless, the pyrolysis of oil palm leaves (OPLs) has received limited attention. In this study, design of experiment‐response surface methodology (DoE‐RSM) was employed to identify the optimal combination of reaction temperature, residence duration, and nitrogen (N₂) flow rate for maximum biochar yield. The elemental analysis, high heating value (HHV), functional group, morphology, pore structure, and thermal behavior were assessed. By varying the operational parameters using response surface methodology, the biochar yield increased by 32.6–85.3%. The DoE‐RSM predicted a theoretical yield of 52.1% at 344 °C, 146 min, and 3.2 scfh N₂ flow rate. The experiment confirmed a comparable yield of 53.7% at the stated parameters. The HHV of 24.14 MJ kg−1 was recorded under optimal conditions, and was comparable to sub‐bituminous and bituminous coal. Fourier transform infrared analysis validated the OPL biochar by weakening O‐H, C=O, C‐OH, and C‐H peaks. Scanning electron microscopy images revealed enlarged pores and altered morphology in the OPL biochar. X‐ray diffraction showed lower crystallinity of the OPL biochar than the feedstock. Raman spectroscopy showed higher ID/IG, indicating a more disordered carbon structure in the OPL biochar. Thermogravimetric analysis confirmed higher temperature for main devolatilization of OPL biochar, and the differential thermogravimetric analysis curve pattern resembled that of Mukah Balingan coal. The findings are helpful for an initiative to convert a large amount of leftover OPLs produced during cultivation and to turn them into high value‐added material for a sustainable contribution to a circular carbon economy.

“…It is inferred that the different morphologies of biochar are not only due to microstructural differences between the various organs of various plants, 25 but also due to the external force on pyrolysis products caused by differences in the composition of bound water and volatile organic compounds in plant feedstocks. 26 According to the results of EDX analysis (Fig. 1 and ESI †), a biochar material containing only C and O elements was GSFB, which was different from that reported by Babu et al, 27 which might be caused by a special process in the degreasing process used in preparing cotton.…”

“…Iberahim et al [41] prepared oil palm fiber-activated biochar at 753 • C for 73 min of activation time with 497 mL/min of CO 2 flow. The pH value of the activated biochar was higher than pure biochar and increased as the activation temperature increased from 600 to 800 • C. The catalyst surface pH provides valuable insights into the adsorption of gas molecules, combining consideration of the acidity and basicity of the target gas molecules.…”

Due to ever-increasing global warming, the scientific community is concerned with finding immediate solutions to reduce or utilize carbon dioxide (CO2) and convert it in useful compounds. In this context, the reductive process of CO2 methanation has been well-investigated and found to be attractive due to its simplicity. However, it requires the development of highly active catalysts. In this mini-review, the focus is on biochar-immobilized nanocatalysts for CO2 methanation. We summarize the recent literature on the topic, reporting strategies for designing biochar with immobilized nanocatalysts and their performance in CO2 methanation. We review the thermochemical transformation of biomass into biochar and its decoration with CO2 methanation catalysts. We also tackle direct methods of obtaining biochar nanocatalysts, in one pot, from nanocatalyst precursor-impregnated biomass. We review the effect of the initial biomass nature, as well as the conditions that permit tuning the performances of the composite catalysts. Finally, we discuss the CO2 methanation performance and how it could be improved, keeping in mind low operation costs and sustainability.
