Fuels derived from biobased materials are attracting attention for their potential in securing the energy supply and protecting the environment. In this Minireview, we evaluate the use of biobased sources, particularly fatty acids and triglycerides from seed oils and animal fats, as fuels. The physical and chemical properties of these fatty acids and triglycerides are discussed, including the link to their sources and current availability to meet fuel demands. The current technologies, also known as the first-generation ones, for converting triglycerides into fuels are covered, including conventional methods such as transesterification, pyrolysis, cracking, and emulsions. Recent, second-generation technological developments that lead to more commercially viable biofuels based on diesel-like hydrocarbons are also discussed.

“…In one such study, Pd has been identified to be an active metal for decarboxylation of fatty acids present in plant oil. In this study, the ability to convert heptanoic acid to octane was investigated using Pd/SiO2 and Ni/Al2O3 catalysts [47][48][49][50]. It was reported that 98% acid conversion was obtained with Pd/SiO2 at 330 o C but only 64% was reported by Ni/Al2O3 [44].…”

“…166 Among a variety of supported metal catalysts and metal loadings, a 5 wt% Pd/C catalyst was found to be the most active and selective agent for deoxygenation of stearic acid to n-heptadecane under He. 173 In addition to deoxygenation of saturated FFAs, 29,168,172 Murzin et al 169 also studied the deoxygenation of unsaturated FFAs and found high product selectivity for the one-less-carbon alkanes. 169 The reaction pathways for deoxygenation of both saturated and unsaturated C18 free fatty acids, including stearic, oleic, and linoleic acids have been investigated by Immer et al 174 In the presence of inert gas, He, or diluted H 2 , the reactions were conducted over a 5 wt% Pd/C catalyst in organic solvents in a semi-batch reactor.…”

Due to continuing high demand, depletion of non-renewable resources and increasing concerns about climate change, the use of fossil fuel-derived transportation fuels faces relentless challenges both from a world markets and an environmental perspective. The production of renewable transportation fuel from microalgae continues to attract much attention because of its potential for fast growth rates, high oil content, ability to grow in unconventional scenarios, and inherent carbon neutrality. Moreover, the use of microalgae would minimize ''food versus fuel'' concerns associated with several biomass strategies, as microalgae do not compete with food crops in the food chain. This paper reviews the progress of recent research on the production of transportation fuels via homogeneous and heterogeneous catalytic conversions of microalgae. This review also describes the development of tools that may allow for a more fundamental understanding of catalyst selection and conversion processes using computational modelling. The catalytic conversion reaction pathways that have been investigated are fully discussed based on both experimental and theoretical approaches. Finally, this work makes several projections for the potential of various thermocatalytic pathways to produce alternative transportation fuels from algae, and identifies key areas where the authors feel that computational modelling should be directed to elucidate key information to optimize the process.
