Influence of microalgae on synergism during co-pyrolysis with organic waste biomass: A thermogravimetric and kinetic analysis

The synergistic influence of microalgae on the two forms organic waste biomasses, namely biomass wastes (BW) and its digested form (DBW), during co-pyrolysis was evaluated based thermal decomposition behaviour, gas yields, extent reaction kinetics. biomasses their blends were co-pyrolysed at three different heating rates (10, 15 20 °C min −1 ) in a thermogravimetric analyzer coupled with mass spectrometer. Initial assessment, TG-DTG data, revealed that degradation can be divided into zones (50-150 °C, 150-550 550-800 °C) for all blends. data used to evaluate kinetic triplet, which include apparent activation energy (E α ), pre-exponential factor ( A mechanism, f (α). Semi-quantitative method quantify species, H 2 , CO dominant implying water reactions oxidation predominant. clearly evident terms kinetics, as noted reduction increase total yields. obtained triplet thermodynamic parameters are expected facilitate design optimization other wastes. • Synergism between dissimilar feedstocks evaluated. Volatiles extractives improved pattern Kinetics yields significantly enhanced. Synergistic effect higher -digested biowaste than microalgae-biowaste Co-pyrolysis reduce input.
