“…71,[74][75][76][77][78][79][80][81][82][83][84] As evidenced by some reports, improvement in Pd-based catalysts in continuous operation may be necessary because some reports suggest they are hindered by rapid deactivation. Maki-Arvela et al 74 reported that the deactivation of a Pd catalyst while decarboxylating lauric acid may have been due to poisoning by the product gases (CO and CO 2 ) and/or coking.…”

“…[5,6] An alternate technology to produce biofuels from microalgal oil is through hydrotreating with Ni, Co and Mo sulfides or noble metal catalysts such as Pd and Pt supported on metal oxides. [7][8][9][10][11][12][13][14] While the high price of the noble metals can be avoided by using the sulfided catalysts, slow desulfurization reduces their activity and contaminates the fuel. [7,9,15] Furthermore, these catalysts have shown poor selectivity, favoring cracking and decarbonylation over hydrodeoxygenation to produce broad hydrocarbon distributions.…”

Iron nanoparticles supported on mesoporous silica nanoparticles (Fe-MSN) catalyze the hydrotreatment of fatty acids with high selectivity for hydrodeoxygenation over decarbonylation and hydrocracking. The catalysis is likely to involve a reverse Mars-Van Krevelen mechanism, in which the surface of iron is partially oxidized by the carboxylic groups of the substrate during the reaction. The strength of the metal-oxygen bonds that are formed affects the residence time of the reactants facilitating the successive conversion of carboxyl first into carbonyl and then into alcohol intermediates, thus dictating the selectivity of the process. The selectivity is also affected by the pretreatment of Fe-MSN, the more reduced the catalyst the higher the yield of hydrodeoxygenation product. Fe-MSN catalyzes the conversion of crude microalgal oil into dieselrange hydrocarbons.

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.
