“…This study is in accordance with the study by Gresinta et al [38] and a comparative review by Dolah et al [39] where the highest component of bio-oil in OPEFB is phenol compounds. Meanwhile, high levels of phenol in bio-oil will affect the high viscosity and acid number which will cause corrosion, decrease the degree of acidity (pH) and reduce the heating value of bio-oil [40][41][42]. So it can be concluded that the low phenol content from the results of this study indicates that the research results are better than previous studies.…”

Biomass waste is one of the promising resource for the production of bio oil. In this study, a mixture of biomass waste will be pyrolyzed in the presence of activated carbon and zeolite as the catalyst. The catalyst concentrations were varied at 2%, 4%, 6%, respectively. While, the pyrolysis process was carried out at 500°C, for 60 minutes, with a nitrogen flow of 3 L/min. The highest bio oil yield was obtained the pyrolysis process by using zeolite with 35% at 4% w/w of the catalyst concentration. The lowest acid number obtained was 42.92 on 4% zeolite catalyst with rice husk biomass as the raw material, the best viscosity was obtained on 4% activated carbon multi feedstock with a viscosity value of 4.96 cP. The best density was obtained in multi feedstock with 4% zeolite catalyst and rice husk with 4% zeolite of 0.996 g/mL.

“…The high volatile matter content indicates a strong potential for liquid oil production during thermochemical conversion, while the slightly higher ash content compared to other coconut fibers suggests a potential reduction in bio-oil yield due to sludge formation [20]. The high carbon content and heating value underscore the suitability of coconut fiber for both biochar and bio-oil production via thermochemical conversion routes [21].…”

The current energy crisis could be alleviated by enhancing energy generation using the abundant biomass waste resources. Agricultural and forest wastes are the leading organic waste streams that can be transformed into useful alternative energy resources. Pyrolysis is one of the technologies for converting biomass into more valuable products, such as bio-oil, bio-char, and syngas. This work investigated the production of bio-oil through batch pyrolysis technology. A fixed bed pyrolyzer was designed and fabricated for bio-oil production. The major components of the system include a fixed bed reactor, a condenser, and a bio-oil collector. The reactor was heated using a cylindrical biomass external heater. The pyrolysis process was carried out in a reactor at a pressure of 1atm and a varying operating temperature of 150˚C, 250˚C, 350˚C to 450˚C for 120 minutes. The mass of 1kg of coconut fiber was used with particle sizes between 2.36 mm -4.75 mm. The results show that the higher the temperature, the more volume of bio-oil produced, with the highest yield being 39.2%, at 450˚C with a heating rate of 10˚C/min. The Fourier transformation Infrared (FTIR) Spectroscopy analysis was used to analyze the bio-oil components. The obtained bio-oil has a pH of 2.4, a density of 1019.385 kg/m 3 , and a calorific value of 17.5 MJ/kg. The analysis also showed the presence of high-oxygenated compounds; carboxylic acids, phenols, alcohols, and branched oxygenated hydrocarbons as the main compounds present in the bio-oil. The results inferred that the liquid product could be bestowed as an alternative resource for polycarbonate material production.

“…Hasil dari reaktor ini bahan baku akan terpecah menjadi fenol dan turunannya, gas (CO2, CO, H2, CH4), dan gas N2. Fenol dan turunannya akan menuju kondensor untuk mengubah dari fase gas menjadi fase liquid dan kemudian didinginkan menggunakan cooler hingga suhu 30 0 C. Hasil dari proses ini didapatkan bio-oil 66% berat bahan baku [4]. Hasil dalam bio-oil ini akan mendapatkan total phenolic compounds sebesar 47,03%.…”

NDONESIA sebagai negara berkembang terus mengupayakan pertumbuhan ekonomi untuk mengatasi krisis moneter akibat pandemi Covid-19 yang berkepanjangan. Salah satu upaya yang dilakukan adalah dengan memanfaatkan sumber daya yang dimiliki Indonesia untuk terus mengembangkan sektor industri. Kementrian Perindustrian pun memprioritaskan lima bidang utama dalam usaha mengimpelementasikan Revolusi Industri 4.0 dan Sustainable Development Goals (SDGs). Lima bidang tersebut adalah kimia, tekstil dan pakaian jadi, automotive, elektronik, serta makanan dan minuman.Fenol atau benzenol merupakan senyawa kimia dengan rumus molekul C6H6O. Sifat fenol cenderung asam dan dapat diugunakan sebagai bahan baku pembuatan plastik, bahan baku pembuatan obat-obat an seperti aspirin, anilin, herbisida, dan resin sintetis, zat pewarna buatan, bahan
