“…As HVOs are hydrocarbons, they comply with conventional diesel fuel requirements (EN 590), with the exception of a low-density value. The criteria of FAME ester (EN 14214) do not refer to HVO [90]. The lower heat output of HVO is significantly higher than ethanol.…”

First, second, third, and fourth-generation biofuels are continuously evolving as a promising substitute to petrodiesel catalyzed by energy depletion, economic and environmental considerations. Bio-diesel can be synthesized from various biomass sources, which are commonly divided into FAME and renewable biodiesel. FAME biodiesel is generally produced by the transesterification of vegetable oils and fats while renewable diesel is produced by hydro-deoxygenation of vegetable and waste oils and fats. The different generation, processing technologies and standards for FAME and renewable biodiesel are reviewed. Finally, the life cycle analysis and production cost of conventional and renewable biodiesel are described.

“…One way of making pyrolysis more efficient is to promote the reaction in the presence of a suitable catalyst. In recent years, studies dealing with the catalytic conversion of oily biomass feeds, through thermochemical reactions, have reported impressive results, and many reviews have summarized Catalysts 2019, 9,418 3 of 13 the positive and negative aspects of such transformations [6][7][8]. Further, current research has been done into the use of multi-element and multi-functional catalysts and complex mixtures of feeds in coprocessing strategies [9][10][11][12].…”

Thermal and Catalytic Pyrolysis of Dodecanoic Acid on SAPO-5 and Al-MCM-41 Catalysts

In this study, dodecanoic acid was decomposed during fast pyrolysis experiments either thermally or in the presence of SAPO-5 and Al-MCM-41catalysts. The catalysts were synthesized by a hydrothermal route and subsequently characterized by XRD, TPD-NH3, and TGA, and dodecanoic acid was characterized by TGA and DSC. Analysis of the post-pyrolysis products was performed online by gas chromatography coupled with mass spectrometry (GC-MS). The results from pyrolysis at 650 °C indicated that the nature of the catalysts strongly influences the composition of the products. Linear alkenes were standard products for all pyrolysis experiments, but with Al-MCM-41, various alkene isomers with a linear and cyclic structure formed, as well as saturated and aromatic hydrocarbons. As a whole, Al-MCM-41 led to a much higher dodecanoic acid conversion and higher deoxygenation than SAPO-5. As these catalysts present small differences in strong acid site density, the difference in the global conversion of dodecanoic acid could be attributed to textural characteristics such as pore volume and surface area. In this case, the textural properties of the SAPO-5 are much lower when compared to Al-MCM-41 and, due to a lower accessibility of the reactant molecule to the acidic sites of SAPO-5, partially blocked for fatty acid molecules by the considerable amount of amorphous material, as detected by XRD.

“…(Zhao et al, 2018). These can occur in multiple reaction processes that include three reversible steps in series, where initially triglycerides are converted to diglycerides followed by the conversion of diglycerides to monoglycerides and in the final step, the monoglycerides are converted to esters and glycerol (Sonthalia et al, 2019).…”

“…In the present work, methanol was used as an alkylating agent under conditions below the critical point in a homemade autogenous intermittent reactor and in the presence of a solid sulfonated carbon acid catalyst, by varying the quantity of catalyst, temperature and reaction time with the purpose of improving reaction efficiency, minimizing production costs comparing to diesel fuel Medina-Valtierra et al, 2017). In a previous study, biodiesel is utilized in a diesel engine where it was demonstrated that there is a decrease of pollutants exposed to the atmosphere during combustion (Sonthalia et al, 2019). However, it is important to mention here that the inventors didn't make required modifications to the diesel engine for the testing of output power and emissions of engine pollutants like NOx, CO, HC and smoke depending on the speed at which the steady-state conditions occur in an engine.…”
