Physical and Chemical Properties of Biodiesel Obtained from Amazon Sailfin Catfish (Pterygoplichthys pardalis) Biomass Oil

Abstract

Amazon sailfin catfish (Pterygoplichthys pardalis) is considered one of the greatest threats to the biodiversity of continental aquatic systems, causing serious economic and environmental problems in the regions. In this work, the production of biodiesel from Amazon sailfin catfish biomass oil is studied. The physical and chemical properties of biofuel produced were evaluated under the specifications of the European standard EN-14214 by using gas chromatography-mass spectrometry, infrared spectroscopy, and atomic absorption spectrometry analyses. The results show that the biodiesel complies with all the specifications of the standard, except the content of polyunsaturated methyl esters. The yields obtained from oil and biodiesel were 9.67 and 90.71% (m/m), respectively. The methyl ester concentrations study identified 17 components where 47.003% m/m corresponded to methyl esters with saturated chains, whereas 34.394% m/m was attributed to monosaturated methyl esters and the remaining (18.624% m/m) to polysaturated methyl esters. Finally, mineral analysis by atomic absorption showed the absence of heavy metals Cd, Ni, and Pb, as well as low concentrations of Ni, Fe, Cu, and Zn, demonstrating that the quality of the fuel is not compromised. The study indicates the feasibility of manufacturing biodiesel using Amazon sailfin catfish biomass oil as a low-cost raw material. It represents an environmental option to mitigate a global problem of atmospheric pollution, and at the same time, it shows a commercial alternative to reduce the ecological impact caused by this fish in the diverse ecosystems to which it has spread. In addition, the great adaptability of this fish provides the possibility of a profitable process to have very high rates of reproduction and growth, allowing the generation of large amounts of biomass for the production of biodiesel.

Nano-synthesis of solid acid catalysts from waste-iron-filling for biodiesel production using high free fatty acid waste cooking oil

“…The Kv obtained as shown in Table 4 are 25.6, 4.1, 3.3 and 3.9 mm 2 /s at a temperature of 40 °C for WCO, RBC500, RBC700 and RBC900 respectively. The Kv of the biodiesel samples fall within the range of the standard and this gives an assurance of quality biodiesel that can combust completely in a CIE without leaving residual residues that can cause damage in the engine 49 . Whereas, Kv of the WCO is about one-sixth far higher than that of the biodiesel samples, an indication of the effect of the trans-esterification process.…”

“…Cloud Point (CP) is the temperature at which the cloud of wax crystals become visible in liquid fuel. This is observed when the fuel is cooled under a controlled environment using the ASTM procedure (ASTM D 2500) 49 . The CP values of the biodiesel samples obtained are shown in Table 4 as + 7, + 5 and + 5 for RBC500, RBC700 and RBC900 respectively.…”

Synthesis and Structural Characterization of Biofuel From Cocklebur sp., Using Zinc Oxide Nano-Particle: A Novel Energy Crop for Bioenergy Industry

“…In the selection of a quality fuel it is an important parameter. Due to high oxygen contents the biofuel caloric value is usually lesser than the diesel fuel (Anguebes et al, 2019). The finding data presented in Table 1 showed that the calorific value of cocklebur crop biofuel is comparatively lower than the petro-diesel fuel.…”
