Valorization of secondary feedstocks from the agroindustry by selective catalytic oxidation to formic and acetic acid using the OxFA process

Abstract The selective oxidative conversion of seven representative fully characterized biomasses recovered as secondary feedstocks from the agroindustry is reported. reaction system, known “OxFA process,” involves a homogeneous polyoxometalate catalyst (H 8 PV 5 Mo 7 O 40 ), gaseous oxygen, p-toluene sulfonic acid, and water solvent. It took place at 20 bar 90 °C transformed agro-industrial wastes, such coffee husks, cocoa palm rachis, fiber nuts, sugarcane bagasse, rice husks into biogenic formic acetic CO 2 sole products. Even though all samples were transformed; remarkably, obtains up to 64, 55% combined yield acid for raw material within 24 h, respectively. In addition role catalysts additive promoting reaction, influence biomass components (hemicellulose, cellulose lignin) formation has been also demonstrated. Thus, these results are major interest application novel oxidation techniques under real producing value-added Graphical abstract
