“…In addition, they present low CO 2 emission rates, which is why they are considered clean and renewable sources of energy, a priority in mitigating the environmental damage caused by the use of fossil fuels [ 2 ]. At an industrial level, biodiesel is obtained mainly by transesterification of vegetable oils with methanol or ethanol in the presence of an acid or base catalyst, to produce the corresponding fatty acid methyl or ethyl esters (FAME) and glycerol [ 3 ]. Biodiesel is produced mainly by homogeneous acid or base catalysis, with remarkable catalytic activity [ 4 ].…”

This research presents results on the production of biodiesel from the transesterification of acylglycerides present in palm oil, using the biocatalysts ZIF-8-PCL and Gly@ZIF-8-PCL synthesized by immobilization of Pseudomonas Cepacia Lipase as catalytic materials and using pure ZIF-8 and Gly@ZIF-8 (modified ZIF-8) as supports. The Gly@ZIF-8 carbonaceous material was prepared by wet impregnation of ZIF-8 with ethylene glycol as the carbon source, and then thermally modified. The calcination conditions were 900 °C for two hours with a heating rate of 7 °C/min in an inert atmosphere. A textural characterization was performed, and results showed superficial changes of materials at the microporous and mesoporous levels for the Gly@ZIF-8 material. Both the starting materials and biocatalysts were characterized by infrared spectroscopy (FTIR) and Raman spectroscopy. During the transesterification, using the two biocatalysts (ZIF-8-PCL and Gly@ZIF-8-PCL), two supernatant liquids were generated which were characterized by infrared spectroscopy (FTIR), gas chromatography coupled to mass spectrometry (GC-MS), and nuclear magnetic resonance (NMR). The results show that the two routes of synthesis of supports from ZIF-8 will be configured as effective methods for the generation of effective biocatalysts for biodiesel production.
