“…This thermochemical process converts biomass into a combustible gas (producer gas) or synthetic gas (syngas). Besides gasification, OPEFB is also converted into biodiesel and bioethanol [10][11][12]. Through the gasification process, the biofuels produced are dimethyl ether (DME), methanol, Fischer-Tropsch mixed alcohols, and hydrogen [13].…”

Biomass from Oil Palm Empty Fruit Bunch (OPEFB) has the potential to be used as feedstock for bio-Dimethyl Ether (bio-DME) production through the gasification process. Bio-DME has the potential to replace liquified petroleum gas (LPG) and biodiesel as it has similar characteristics to both fuels. Therefore, this study was aimed to evaluate previous research on the OPEFB-based bio-DME and its sustainability, to identify existing gaps in the research and to formulate directions for valuable future research. The results showed that pertinent performances with simulation and technical analyses should be conducted with different process configurations and under different scenarios. Based on this review, a number of further topics should still be investigated, including the economic feasibility of OPEFB conversion into bio-DME at different locations and plant capacities; the simulation of OPEFB bio-DME plant using an indirect synthesis method and technical analysis of pilot plant; and the sustainability of OPEFB-based bio-DME in Indonesia on islands with a large concentration of oil palm plantations.

Research on the transformation of Oil Palm Empty Fruit Bunches (OPEFB) through pretreatment process using ionic liquid triethylammonium hydrogen sulphate (IL [TEA][HSO4]) was completed. The stages of the transformation process carried out were the synthesis of IL with the one-spot method, optimization of IL composition and pretreatment temperature, and IL recovery. The success of the IL synthesis stage was analyzed by FTIR, H-NMR and TGA. Based on the results obtained, it showed that IL [TEA][HSO4] was successfully synthesized. This was indicated by the presence of IR absorption at 1/λ = 2814.97 cm−1, 1401.07 cm−1, 1233.30 cm−1 and 847.92 cm−1 which were functional groups for NH, CH3, CN and SO2, respectively. These results were supported by H-NMR data at δ (ppm) = 1.217–1.236 (N–CH2–CH3), 3.005–3.023 (–H), 3.427–3.445 (N–H+) and 3.867 (N+H3). The TGA results showed that the melting point and decomposition temperature of the IL were 49 °C and 274.3 °C, respectively. Based on pretreatment optimization, it showed that the best IL composition for cellulose production was 85 wt%. Meanwhile, temperature optimization showed that the best temperature was 120 °C. In these two optimum conditions, the cellulose content was obtained at 45.84 wt%. Testing of IL [TEA][HSO4] recovery performance for reuse has shown promising results. During the pretreatment process, IL [TEA][HSO4] recovery effectively increased the cellulose content of OPEFB to 29.13 wt% and decreased the lignin content to 32.57%. The success of the recovery process is indicated by the increasing density properties of IL [TEA][HSO4]. This increase occurs when using a temperature of 80–100 °C. The overall conditions obtained from this work suggest that IL [TEA][HSO4] was effective during the transformation process of OPEFB into cellulose. This shows the potential of IL [TEA][HSO4] in the future in the renewable energy sector.
