“…Yun et al [31] recently proposed an alternative concept to the conventional gasification-cleaning-methanation train, illustrating the use of biomass pyrolysis followed by low-temperature steam reforming of bio-oil as a promising strategy for the direct production of biomethane with high carbon conversion efficiency. The improvement of carbon efficiency in biomass-to-biomethane systems can also be addressed through the capture and utilization of carbon streams rejected by the process that could be further exploited on site to produce renewable commodities.…”

Biological methanation (biomethanation) of syngas obtained from biomass gasification offers the opportunity to employ a low-pressure, low-temperature process to produce storable bio-derived substitute natural gas (bSNG), although its economic viability is limited by high energy and biomass costs. Research on syngas biomethanation techno-economic performance is limited and novel biomass-to-biomethane process configurations are required in order to assess opportunities for the enhancement of its efficiency and economic feasibility. In this study, we carried out the techno-economic modeling of two processes comprising integrated biomass gasification, electrolysis, and syngas biomethanation with combined heat and power recovery in order to assess and compare their fuel yields, energy efficiency, carbon efficiency, and bSNG minimum selling price (MSP). The first process operates standalone biomethanation (SAB) of syngas and can produce approximately 38,000 Nm3 of bSNG per day, with a total plant efficiency of 50.6%. The second process (integrated biomethane-biomethanol, IBB) exploits the unconverted carbon stream from the biomethanation process to recover energy and synthesize methanol via direct catalytic CO2 hydrogenation. In addition to the same bSNG output, the IBB process can produce 10 t/day of biomethanol, at a 99% purity. The IBB process shows little global energy efficiency gains in comparison with SAB (51.7%) due to the large increase in electrolytic hydrogen demand, but it shows a substantial improvement in biomass-to-fuel carbon efficiency (33 vs. 26%). The SAB and IBB processes generate a bSNG MSP of 2.38 €/Nm3 and 3.68 €/Nm3, respectively. Hydrogenation of unconverted carbon in biomass-to-biomethane processes comes with high additional capital and operating costs due to the large-scale electrolysis plants required. Consequently, in both processes, the market price gap of the bSNG produced is 0.13 €/kWhbSNG (SAB) and 0.25 €/kWhbSNG (IBB) even under the most optimistic cost scenarios considered, and it is primarily influenced by the cost of surplus electricity utilized in electrolysis, while the selling price of biomethanol exerts a very limited influence on process economics. Intensive subsidization would be required in order to sustain the decentralized production of bSNG through both processes. Despite their limited economic competitiveness, both processes have a size comparable with existing renewable gas production plants in terms of bSNG production capacity and the IBB process is of a size adequate for the supply of biomethanol to a decentralized biorenewable supply chain.

“…Indonesia, Malaysia, Thailand, Colombia, and Nigeria are the five top oil palm producers Oil palm's empty bunches of palm fruit are waste generated from the palm oil industry, this is also a significant issue in managing and reducing waste of empty bunches of palm fruit (Ong et al, 2020). Several studies and experiments have been conducted to improve the sustainability of the palm oil industry by utilizing empty bunches of palm fruit into various other products (Yun et al, 2020) combustion, and the processing of empty bunch fibers of palm fruit for natural adsorbent materials, including adsorbents that can be used in handling oil spill disasters. Even Malaysia has conducted research and experiments to use empty bunches of palm fruit as an ingredient to produce bioethanol (Derman et al, 2022).…”

The oil spill disaster potentially occurance is an inseparable part of oil, gas exploration and transportation activities that are national and international concern. Oil palm’s empty bunches are a non-toxic material that is cheap, renewable, and widely found in Indonesia as one of the world's palm oil producing countries and can be used to deal with environmental pollution. Research that has been conducted in Malaysia has found that the fiber of eoil palm’s mpty bunches has good absorption in diesel oil spills. This writing method is with literatur review and compares the conditions in Malaysia with Indonesia. This paper aims to provide a comparison of the utilization and use of oil palm’s empty bunches for the benefit of handling oil spills in the waters. In conclusion, Malaysia is more advanced in conducting research and utilizing oil palm’s for adsorbent to spills that can also be done in Indonesia.

“…To allow the experimental and numerical study of multicomponent fuels, the formulation of surrogate fuels is a common practice in combustion science, − with the purpose of mimicking the physical and chemical properties of the real fuels. From a modeling perspective, they are of the utmost importance, since the availability of kinetic mechanisms and thermodynamic properties for each of the components allows to study the fuel mixture as a whole, as well as to understand the mutual interactions between the different species during their evaporation and combustion.…”

Fast biomass pyrolysis is an effective and promising process for high bio-oil yields, and represents one of the front-end technologies to provide alternative, sustainable fuels as a replacement of conventional, fossil-based ones. In this work, the effect of droplet initial diameter on the evaporation and ignition of droplets of crude fast pyrolysis bio-oil (FPBO) and FPBO/ethanol blend (50% vol) at ambient pressure is discussed. The experimental tests were carried out in a closed single droplet combustion chamber equipped with optical accesses, using droplets with a diameter in the range of 0.9–1.4 mm. The collected experimental data show a significant effect of droplet diameter and initial fuel composition on the evaporation and combustion of the droplets. At the same time, 1-dimensional modeling of the evaporation and ignition of different droplets of crude FPBO and its blend with ethanol is performed to understand the complex physical and chemical effects. To this purpose, an 8-component surrogate was adopted, and a skeletal mechanism (170 species and 2659 reactions) was obtained through an established methodology. The comparison of numerical and experimental results shows that the model is able to capture the main features related to the heating phase of the droplet and the effect of fuel composition on droplet temperature and evaporation, particularly the increased reactivity following ethanol addition and the variation of diameter with time. Also, a sensitivity analysis highlighted the reactions controlling the autoignition of the droplets in the different conditions. It was found that the autoignition of pure FPBO droplets is governed by dimethyl furane (DMF), because of its high volatility and in spite of not being the most abundant species. On the other side, ethanol chemistry drives the gas-phase ignition in the case of the blended (50/50 v/v) mixtures, due to its higher volatility and reactivity.
