| Abstract |
Opuntia Ficus Indica (OFI) cladodes slow pyrolysis was conducted in a fixed-bed reactor at various temperature (500-600-700 degrees C) and residence time (30-60-120 min) with a constant heating rate (10 degrees C min(-1)). The highest biochar yield (40.08%) was obtained at 500 degrees C and 30 min whereas more liquid (35.03%) and gaseous (31.08%) products were produced at 700 degrees C and 120 min. The produced biochar is an alkaline carbon rich with minerals and nutrient (N, P, K, Ca, Mg) that could be applied in agriculture to balance acidic soil. The obtained bio-oil and syngas could be used as green biofuels. The kinetic study using Vyazovkin and FWO indicates an activation energy (E alpha) values of 36.05-224.41 and 47.87-242.36 kJ mol(-1) respectively, with a good prediction (R-2 >= 0.9). This integrated approach of local OFI biomass conversion into biofuels and bio-based materials is an opportunity for the implementation of a local circular economy in Tunisia. |
