SUMMARY:

The growing demand for energy and the dependence on fossil fuels have led to significant environmental impacts, such as greenhouse gas emissions that contribute to global warming and environmental degradation. In this context, electrochemical methods emerge as promising and sustainable alternatives to produce biofuels and fine chemicals products, reducing the need for energy-intensive thermocatalytic processes. This work aimed to develop an electrocatalytic methodology for the decarboxylation of fatty acids (C8–C18), obtained through the hydrolysis of commercial coconut oil, targeting the synthesis of higher value-added compounds. The reactions were carried out using graphite electrodes under ambient temperature and pressure conditions, and the products were analyzed by gas chromatography coupled with mass spectrometry (GC-MS). The system achieved 100% conversion, primarily producing olefins (C9–C17) with moderate selectivity (≥50%). The olefins stood out as potential fuel additives, contributing to the reduction of harmful gas emissions. The developed methodology demonstrates high potential as an alternative and sustainable route for obtaining hydrocarbons and renewable-based chemical products, operating under exceptionally mild reaction conditions.
