“…Di-t-butyl polysulfide (LU) was obtained from Lubrizol (Wicklie, OH, USA). The NiW/SiO 2 -Al 2 O 3 commercial catalyst (CC) containing 6.4 wt % W and 17.5 wt % Ni was used [30]. The second used catalyst was a laboratory-prepared catalyst on a phonolite support (PH) with 5 wt % Ni and 10 wt % W [26].…”

The production of bioethylene and biopropylene is a promising method for reducing the environmental impact of the plastic industry. Although their production from bioethanol is currently the most studied method, in this study, favorable alternative biofeedstocks were used: rapeseed oil and waste rendering fat. This study focuses on complex feedstock‐to‐product processes that are usable in established industrial units. The first step is catalytic hydrodeoxygenation and hydrocracking. The hydrodeoxygenation conditions were fine‐tuned to induce hydrocracking, and three catalysts, namely, NiW/SiO2‐Al2O3, NiW/phonolite, and WV/TiO2, were tested. The final step was microscale pyrolysis, which was applied to evaluate the product yields. The best yields for both feedstocks were obtained with the NiW/SiO2‐Al2O3 catalyst at 425 °C.

“…It is widely used in the industry for hydrocracking petroleumheavy fractions to produce suitable light products. The same catalyst has been used by the authors and reported in previous references [36,37]. As the catalyst was commercially sourced, detailed information about the fresh or used catalyst samples is not included in the manuscript.…”

Nowadays, transportation fuels such as diesel or gasoline are standardly produced from crude oil refining. These petroleum-based products are gradually replaced by more environmentally friendly sources, such as Fischer–Tropsch diesel fractions and other biofuels. The present work reports the distillation of Fischer–Tropsch (FTS) waxes and its use for fuel production by (i) blending the FTS wax diesel fraction with fossil diesel (7:93; 15:85; 30:70; and 50:50 wt.%) and (ii) blending the FTS wax heavy fraction (360–700 °C) with vacuum gas oil (10–50 wt.%) followed by hydrocracking at industrial operating conditions (T = 420 °C, WHSV = 0.5–1.0 h−1, P = 10.0 MPa). The obtained products in both cases were analysed and compared with standard EN590 for petroleum-diesel fuels. Overall, our results point to the suitability of the distillation of FTS waxes for renewable fuel production, either by straight blending of the diesel petroleum-based products or co-hydrocracking of the heavy fraction with vacuum gas oil.

“…The hydrotreating with hydrogen of most vegetable oils in the presence of metal oxide catalysts, leads to the production of a liquid blend of C15-C18 hydrocarbons, exhibiting a boiling point within the range of diesel, so that it is commonly called "green diesel", "renewable diesel", or "bio-hydrogenated diesel", and therefore with the same chemical behavior that petroleum-derived diesel. This technology has been extended to the application of hydrocracking treatments to mixtures of vegetable oils with fractions of heavy petroleum crude, of equivalent molecular weights in conventional oil refineries [355][356][357][358][359][360][361][362][363][364][365][366][367][368][369][370][371][372][373][374]. Therefore, this procedure makes possible to transform triglycerides into high quality diesel fuel, with the facilities already available in conventional oil refineries, using specific catalysts.…”

Biodiesel at the Crossroads: A Critical Review

The delay in the energy transition, focused in the replacement of fossil diesel with biodiesel, is mainly caused by the need of reducing the costs associated to the transesterification reaction of vegetable oils with methanol. This reaction, on an industrial scale, presents several problems associated with the glycerol generated during the process. The costs to eliminate this glycerol have to be added to the implicit cost of using seed oil as raw material. Recently, several alternative methods to convert vegetable oils into high quality diesel fuels, which avoid the glycerol generation, are being under development, such as Gliperol, DMC-Biod, or Ecodiesel. Besides, there are renewable diesel fuels known as “green diesel”, obtained by several catalytic processes (cracking or pyrolysis, hydrodeoxygenation and hydrotreating) of vegetable oils and which exhibit a lot of similarities with fossil fuels. Likewise, it has also been addressed as a novel strategy, the use of straight vegetable oils in blends with various plant-based sources such as alcohols, vegetable oils, and several organic compounds that are renewable and biodegradable. These plant-based sources are capable of achieving the effective reduction of the viscosity of the blends, allowing their use in combustion ignition engines. The aim of this review is to evaluate the real possibilities that conventional biodiesel has in order to success as the main biofuel for the energy transition, as well as the use of alternative biofuels that can take part in the energy transition in a successful way.
