“…Biomass (organic material) can be acquired from forests, agricultural wastes, household wastes, plantations and industries. Hydrocarbon compounds contained in biomass could yield heat energy producing fuels (Fardhyanti and Damayanti, 2017; Montevecchi, 2016). Biomass holds promise as a good feedstock for generating liquid fuels in the imminent future (Demiral and Ayan, 2011; Ilknur et al., 2012; Donate, 2014; Joardder et al., 2015).…”

The Swietenia macrophylla wood used for the study was sun dried for about 48 h, pulverized using a hammer mill and then sieved to a particle size of about 425μm using Wiley milling machine. The prepared materials were pyrolyzed in a fixed-bed pyrolysis reactor in the temperature range from 425 to 500 °C. The product yields were collected at an interval of 25 °C. The maximum yield of bio-oil was recorded as 69.5wt.% at the pyrolysis temperature of 450 °C. The physicochemical properties and compositions of the feed materials and produced bio-oil were measured in order to quantify their potential for bio-energy use and industrial applications. The properties specifically measured include density, moisture content, ash content, pH, refractive index, cetane index, elemental composition, viscosity, and heating values. The ultimate analysis of the product showed that the contents of carbon, oxygen, hydrogen, nitrogen, and sulfur were 50.2%, 42.6%, 6.6%, <0.4% and <0.06% respectively. The viscosity, density, pH, moisture content, API gravity, ash content, HHV and LHV of bio-oil produced were found to be 4.6 mm 2 /s, 0.951 g/ml, 5.64, 21.4wt.%, 19.29, 0.15wt%, 29.52 MJ/kg and 28.08 MJ/kg respectively. These values were found to be in the ranges of values reported in the literature for bio-oils produced from biomass. The produced bio-oil had the much needed organic compounds typical of other woody biomass employed in commercial bio-oil manufacture. These compounds were classified into several groups; organic acids, ketones, phenols, alcohols, and aldehydes. The main components identified in the bio-oil are the aromatic and aliphatic compounds as well as carboxyl groups. The GCMS analysis of the product indicated the presence of 24 compounds which are useful as industrial chemicals and flammable gases: they include alkanes, alkenes, phenols, hydrogen, and levoglucosan. This study on bio-oil has demonstrated that mahogany wood is a useful biomass for the much sort potential fossil fuel substitute and finds vast application in the biofuel industry.

“…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.

Bio-oil is an environmentally friendly liquid fuel produced from the condensation of vapor product of pyrolysis process. Bio-oil has higher calorific value compared to other oxygenated fuels (such as methanol), but its calorific value is still lower than diesel and other light fuel oils. Bio-oil can be used directly as fuel; however, it has several characteristics that adversely affect high-tech machines. Bio-oil is corrosive since it has a high acidity level, unstable at room temperature due to the high content of oxygenate compounds and has a low higher heating value (HHV) due to its high water content. Therefore, an upgrading process is needed to improve the quality before it can be further processed into liquid fuel and chemicals. Meanwhile, the raw material for bio-oil also varies, not only using single feedstock but also using mixed feedstock. However, studies on mixed bio-oil raw materials are still very limited. Thus, it is possible to study the process of producing bio-oil from a mixture of biomass waste using the catalytic pyrolysis method and improve the quality of bio-oil through the collection of phenolic compounds using the extraction process.
