“…The hydrotreating process is a well-known catalytic technology, which has been exploited for several decades by the petrochemical industry to remove heteroatoms such as N and S from hydrocarbon feedstocks. This route has been successfully adapted to transform oxygenated feedstocks such as vegetable oils into hydrocarbon fuels in the diesel and jet range, and a large number of works have been described in the literature in the last few years [37][38][39]. While excellent Catalysts used for the hydrotreating of vegetable oils include noble metal-supported materials and, to a greater extent, alumina-supported metal (e.g., Co, Mo, Ni, W) sulfides similar to those used in the petrochemical industry for the removal of heteroatoms such as nitrogen or sulfur [16][17][18][19].…”

Concerns about depleting fossil fuels and global warming effects are pushing our society to search for new renewable sources of energy with the potential to substitute coal, natural gas, and petroleum. In this sense, biomass, the only renewable source of carbon available on Earth, is the perfect replacement for petroleum in producing renewable fuels. The aviation sector is responsible for a significant fraction of greenhouse gas emissions, and two billion barrels of petroleum are being consumed annually to produce the jet fuels required to transport people and goods around the world. Governments are pushing directives to replace fossil fuel-derived jet fuels with those derived from biomass. The present mini review is aimed to summarize the main technologies available today for converting biomass into liquid hydrocarbon fuels with a molecular weight and structure suitable for being used as aviation fuels. Particular emphasis will be placed on those routes involving heterogeneous catalysts.

“…The major supplier of aviation biofuel is the HEFA process, a technology that has been proved on a commercial scale, principally for diesel production. Nevertheless, high feedstock costs and restricted availability of sustainable vegetable oil sources pose significant barriers that restrain the boost of HEFA technologies . Hence, it is crucial to design and implement novel biojet fuel conversion routes that would be able to operate at large scale and utilise sustainable feedstocks such as abundant lignocellulosics including agricultural wastes, forestry residues, or municipal solid waste.…”

As the investment in immature technologies comes at high risk, techno-economic analyses and comparisons of promising processes are vital to deliver better-quality predictions of the related costs and possible profits.…”

Summary The aviation industry continues to grow, and consequently, more fuel is needed. With the intention of decarbonising the aviation sector, sustainable routes that have the potential to mitigate emissions, such as biomass fast pyrolysis, can positively contribute to this direction. Within this context, the present study performs a comparative techno‐economic evaluation of aviation biofuel manufacture via the main bio‐oil upgrading pathways, namely, hydroprocessing (HP), gasification followed by Fischer‐Tropsch synthesis (G+FT), and zeolite cracking (ZC). The research constitutes the first endeavour to investigate and compare the feasibility of producing biojet fuel via pyrolysis‐based routes. The presented work provides an inclusive evaluation that comprises process modelling and financial assessment. Based on the simulations, overall energy efficiencies of 48.8%, 45.73%, and 45.38% and jet fuel energy efficiencies of 23.70%, 21.45%, and 20.53% were calculated, while the implementation of a discounted cash flow analysis estimated minimum jet fuel selling prices (MJSPs) of 1.98, 2.32, and 2.21 $/L for the HP, the G+FT, and the ZC, respectively. Sensitivity analysis revealed that the processes are capital and feedstock intensive while an increase to the bio‐oil yield will favour the economic performance of the examined biorefineries. An increase of the plant size from 100 (base case) to 150 dry tonnes per hour of feedstock will decrease the selling prices by approximately 25% for all cases. Monte Carlo simulations exhibited that without establishing and/or maintaining appropriate policy schemes, there is no pragmatic prospect for the examined biorefineries to beat the competition against the prevailing oil infrastructures.

“…Because of the climate change due to the increase in carbon emissions, the aviation industry has come in the public spotlight. This has encouraged the development of renewable and clean fuels produced from alternative sources . Hydroconversion of vegetable oils to obtain bio‐jet fuel is considered as a promising strategy in this regard , .…”

The influences of impurities and oxidation evolution of waste cooking oil on the preparation of bio-jet fuel via hydroconversion were studied. The hydrogenation active sites and acid sites were covered by heavy metals, sulfides, and basic nitrogen compounds, resulting in the increase of selectivity for bio-jet fuel by decreasing the selectivity of diesel, aromatics, and iso-alkanes. The effects of impurities, oxidation on the reaction pathway, and product distribution became more distinct with higher catalyst acidity. The evolution and variation of naphthalene, indan, and phenanthrene obtained from cyclic fatty acids influenced the properties of fuel or evoked the catalyst deactivation. This work will help to design new catalysts for selective conversion of waste cooking oil into bio-jet fuel.
