Analysis of Bio-Oil of the Thermal and Catalytic Pyrolysis of Yellow Passion Fruit Peel

Brazil is the world's largest producer of passion fruit, and the peel, rich in hemicellulose, cellulose, and lignin, is often discarded as organic waste. This study used thermal pyrolysis to convert the peel of sour yellow passion fruit into new fractions of bioproducts. The pretreatment was carried out using a kinetic test, adjusted according to the Newton model, and the samples were heated to 450°C for 30 minutes. Thermal and catalytic pyrolysis resulted in three-states. GC-MS analysis showed that the use of CaO as a catalyst modified the composition of the pyrolytic liquid. ¹³ C and ¹ H NMR analysis indicated the presence of -CH ₂ and -CH ₃ groups, as well as alcoholic hydrogen. It was concluded that pyrolysis is a sustainable route to residue decreases, waste and generate new product fractions, with possible added value in the market.
