Biofuels play a crucial role in the transition to a more sustainable and environmentally friendly energy matrix. The oil obtained from the seeds of the fruit of Pachira aquatica Aubl. (PAA), also known as Munguba, stands out as a promising source of raw material to produce biofuels and chemical compounds of industrial interest, through thermochemical conversion processes. Its composition has significant amounts of saturated fatty acids, especially palmitic acid (C16:0), along with the unsaturated fatty acids oleic (C18:1) and linoleic (C18:2). The objective of this study is to characterize the seeds and oil from PAA with a focus on evaluating their energy potential to produce 2G drop-in advanced biofuels and valuable products for the chemical industry. The seeds were collected, and after cleaning and characterization, the oil was extracted by mechanical pressing. Among the seed characterizations, the ash content (4.05%), moisture (3.09%), volatile components (91.79%) were consistent with previous studies carried out on seeds of the same species. From the extracted oil, a satisfactory yield of 36.0% was observed, in addition to notable thermal stability, withstanding temperatures of up to 250 °C and presenting a high calorific value (37.94 MJ/kcal). Comprehensive physicochemical analyses, including ash, density, viscosity and determination of acidity, iodine, saponification, peroxides, and refraction indices were carried out. A preliminary study using conventional analytical pyrolysis of the oil revealed a predominance in the formation of aliphatic hydrocarbons in the C7-C18 range, with a low number of oxygenated compounds. In catalytic pyrolysis using zeolite type HZSM-5, a significant reduction in oxygenated compounds was observed, with the predominance of aliphatic hydrocarbons in the ranges of C4-C13 at 500 °C and of C7-C14 at 300 °C, with characteristic of drop-in aviation fuels. From these data, a 32 factorial design was carried out in conjunction with the principal component analysis (PCA) and response surface (RSM) methodology to investigate the effect of the independent temperature variables of the catalytic windmill (300, 400 and 500 ° C) and the biomass/catalyst ratio (2, 6 and 12 mg of catalyst) in the response variables, such as hydrocarbon content by the number of carbons in the chains and compound content by range of biofuels. The best condition was shown to be with the lowest temperature (300 °C) and smallest amount of catalyst (2 mg) showing better distribution of products in the gaps of gasoline (46.5%), diesel (91.2%), kerosene (56.8%) and lubricating oil (54.8%). In all variations of catalytic bed temperatures there was no formation of oxygenated products and a high yield of aromatic compounds, including benzene, toluene, ethylbenzene, and xylene (BTEX), which are products of great industrial interest. The use of the HZSM-5 catalyst provided an improvement in the products formed, due to its ability to promote decarbonization, decarbonylation, deoxygenation and aromatization of structures, due to its acidic properties and porous structure. These results point to the significant potential for application of PAA seed oil in obtaining advanced drop-in biofuels and selectivity in aromatic bioproducts for the chemical industry.
