“…Biofuel technology is one of the best methodology to manage the invasive plants by converting them into bioenergy which can reduce the greenhouse gas (GHG) emission (Reza et al 2019b, a). Pyrolysis, gasification and hydrothermal carbonization are the major processes to convert biomass into biochar, bio-oil, and biogas (Hidayat et al 2018;Radenahmad et al 2020). From the biomass conversion products, biochar has attracted attention globally due to its huge surface area, functional groups, pore structure, and high inorganic substance (Huang et al 2019).…”

Pennisetum purpureum is one of the most invasive perennial grasses of the Poaceae family, which are abundant in southeast Asia including Brunei Darussalam. The pyrolysis process at a slow heating rate proved to be highly promising for biochar production. The production and characterization of different Pennisetum purpureum biochars have been investigated at the pyrolysis temperatures of 400 °C, 500 °C and 600 °C with a heating and nitrogen flow rate of 5 °C/min and 0.5 L/min, respectively. The observed higher heating values were 22.18 MJ/kg, 23.02 MJ/kg, 23.75 MJ/kg, and the alkaline pH were 9.10, 9.86, 10.17 for the biochar at 400 °C, 500 °C, 600 °C temperatures, respectively. The water holding capacity was one hundred percent for all biochars and continued to increase for higher pyrolysis temperature. SEM images show that the porosity of the biochars has been enhanced with increased temperatures due to the rearrangement of crystallinity and aromaticity. On the other hand, the yields of biochar have been decreased from 35.13% to 23.02% for the increase of pyrolysis temperature from 400 °C to 600 °C. Energy dispersive X-ray analysis shows that the O/C atomic ratios were 0.15, 0.08 and 0.06 for the biochar of 400, 500 and 600 °C which validates the improvement in heating values. FT-IR analysis revealed that the available functional groups in the biochars were CO , C=C, and C-H. Thermogravimetric analysis (TGA) under pyrolysis condition showed residue of 46.56%, 51.13% and 55.67% from the biochar at 400, 500, and 600 °C, respectively. The derivative thermogravimetry (DTG) graph indicates that the degradation rate is higher for 400 °C biochar than the 600 °C biochar.

The production of bio-oil from biomass as renewable sources has been trusted as a suitable alternative in supplying future energy needs. Present in abundance amounts as crop residues cassava stems is potential biomass tobe utilized. As raw material, it has advantages such as fast and easy growth, minimal maintenance and utilizing plantation land without competing with food supply. The biomass characterization results showed that cassava stems containing cellulose, hemicellulose and lignin, respectively 40.16, 25.66 and 16.65% w/w. Cassava stems has low ash content and high of volatile matter with high carbon and low nitrogen.The HHV of cassava stems was19.08 MJ/kg.Physical propertiesby GC-MS tests of bio-oil produced via electromagnetic-assisted catalytic liquefaction(EA-CL)revealedthat the dominant content of chemicals were 5-methyl furfural, 2-furancarboxaldehyde and acetic acid.The bio-oil density ranged from 0.979 to 0.984 g/mL and has a pH of 2.8. This result shows that cassava stemis appropriate biomass for further bio-oil production feedstock.Bio-oil using EA-CL process meets bio-oil standards.

“…Pyrolysis is among the conversion routes that are used for converting solid waste and residue biomass feedstocks into liquid biofuels. It is a thermochemical conversion technology that the process occurs in the absence of oxygen to convert biomass into bio-char, bio-oil, and pyrolysis gas at elevated temperatures [3,4]. Bio-oil is a viscous free-flowing dark brown or black organic liquid obtained from pyrolysis containing a complex mixture of different compounds such as acids, aldehydes, ketones, furans, pyrans, sugars, benzenes, catechols, phenols, guaiacols, and syringols [5,6].…”

Catalytic fast co-pyrolysis of sewage sludge and sawdust was performed using Py/GC-MS for pyrolytic product upgrades. Metal oxides (NiO and MoO3) and ZSM-5 catalysts had been introduced into single catalytic pyrolysis. The combination of NiO + MoO3 in mixed metal oxides (MMOs) was modified with ZSM-5 under a dual-catalyst with different catalytic layouts. In the pyrolysis process, the metal oxides specifically promoted the formation of phenols, ketones, and furans. ZSM-5 was proven to be more effective in producing aromatic hydrocarbons and phenols and in reducing the oxygenated compounds. The combination of MMOs with ZSM-5 effectively improved product distribution by increasing the production of aromatics and phenols. MMOs promoted the aromatics selectivity of undesirable PAHs (70.5 %), however, the addition of ZSM-5 to MMOs appeared to reduce and inhibit the formation of PAHs by 0.85 %. The highest yield of aromatics was obtained by the layout of the ZSM-5/MMO dual catalysts layout which was 21.6 %. Dual catalysts of MMOs and ZSM-5 in separated layout created promising effects in further Manuscript File increasing the production of aromatic hydrocarbons and phenols compared to the mixture of MMOs modified ZSM-5.
