“…, it could be concluded that for production of more liquid biofuels, a shorter HTL process would be more effective compared to HTL with longer processing time which is convenient for higher solid fuel production. The operation of the fast HTL is primarily based on the feed composition . The size of biomass particles also plays an important role since it has a positive impact on the microalgae biomass compared to other biomass sources.…”

Microalgal biomass processing by continuous hydrothermal liquefaction (HTL) has recently received much interest and can be used to convert microalgal biomass to biocrude oil and drop‐in fuels. This review focuses on the conversion of microalgae biomass to energy production through continuous HTL processes. In addition, processes for upgrading feedstocks and biocrude are also discussed. The feed of the biomass slurry is treated according to size and moisture regulations. Following separation of the gaseous, liquid, and solid phases, the determination of elemental, physical, and chemical fragments, yield of energy, and other properties of the various products is carried out. Homogeneous or heterogeneous catalysts improve the biocrude yield and quality as does higher moisture content. The high percentage of N2 and O2 in the feedstock results in lower quality products. This may be resolved through pre‐processing of the biomass, controlling of HTL processes conditions, and post‐upgrading processing of the HTL products. The promising potential of microalgae biomass for biocrude and drop‐in fuels may have an important contribution to the world's renewable energy sources through HTL in the near future.

“…are in practice and aiding the energy demand to some extent. [1,4] But another concern swoops in is regarding the sustainability of carbon element which can be utilised in the production of transportation fuel or platform chemicals. Undoubtedly, out of all renewable energy resources, only biomass provides the sustainable carbon.…”

“…Undoubtedly, out of all renewable energy resources, only biomass provides the sustainable carbon. [1,4,5] Further about the biomass requirement, the lignocellulosic biomass, for instance, agricultural wastes, municipal wastes, forestry wastes, energy crops, etc., is easily available and inexpensive in most of the countries. Because of its easy availability and being inexpensive, the lignocellulosic biomass is the most preferred choice among researchers for the production of bio-oils/biofuels.…”

“…There are many channels to upgrade the bio-oil, e. g., hydrodeoxygenation, ketonization, zeolite upgrading, etc., but the hydrodeoxygenation of bio-oil is found to be viable. [1,4,8,10] Recently, the catalytic hydrodeoxygenation of pyrolytic bio-oil has been reviewed by several researchers.

The bio‐oil produced from pyrolysis of lignocellulosic biomass comprises of several oxy‐catalogues such as acids, alcohols, aldehydes, furans, phenols, etc. The oxy‐functionals in the bio‐oils vitiate the quality of bio‐oil, therefore, the unprocessed bio‐oils cannot be used directly to transportation vehicles. In this work, 2‐hydroxybenzaldehyde (2‐HB) has been taken as bio‐oil model component and carried out seven reaction pathways to produce benzene and other important intermediate products such as phenol, benzaldehyde, etc. The first reaction pathway is about the cleavage of formyl group of 2‐HB followed by single step hydrogenation reaction to produce phenol which further produces benzene component. The reaction pathway 2 is the hydrogen migration reaction followed by cleavage of formyl group and the reaction pathway 3 is decarbonylation reaction of 2‐hydroxybenzaldehyde to produce phenol component. The reaction pathway 4 is single atom hydrogenation at the aromatic carbon of Caromatic‐CHO sigma bond followed by the removal of formyl group to produce phenol. Similarly, the reaction pathway 5 starts with a single atom hydrogenation at the aromatic carbon of Caromatic‐OH sigma bond followed by hydroxyl group removal to produce benzaldehyde component. The reaction pathway 6 is the dehydrogenation reaction of formyl group followed by CO removal and a single step hydrogenation to produce phenol. The reaction pathway 7 directly cleaves the hydroxyl functional followed by hydrogenation reaction to produce benzaldehyde which further follows two sub‐pathways to produce benzene. The direct cleavages of hydroxyl and formyl functionals are not favourable as they require very high amount of energetics. Instead, the single atom hydrogenation to the aromatic carbon of Caromatic‐X (X=•OH or •CHO) followed by the oxy‐functional removal is found to be favourable reaction pathway.

Highly phenol substituted bio‐oil–phenol–formaldehyde (BPF) adhesives were prepared via the phenolization‐copolymerization method, in which furfural was used as a novel crosslinking agent to improve the bonding performance. The effects of bio‐oil percentage, furfural content, curing temperature, and pressure on the performance of BPF adhesives have been studied in detail. A BPF adhesive with 75% bio‐oil percentage and 15% furfural loading (named 75BPF_15) was synthesized, which was cured at 180 °C and 4 MPa. Compared to the conventional phenol–formaldehyde adhesive, the wet tensile strength of 75BPF_15 adhesive reached 2.84 MPa, which was significantly higher than the 1.54 MPa of PF. A possible mechanism of BPF adhesives crosslinked with furfural is proposed. © 2018 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2019, 136, 46995.
