Assessment of reducing sugars production from agro-industrial wastes by batch and semicontinuous subcritical water hydrolysis

Reducing sugars produced from agro-industrial wastes by means of hydrolysis represent a promising alternative chemicals and energy. Yet, large scale production still struggles with several factors involving process complexity, degradation, corrosion, enzyme recyclability, economic feasibility. More recently, sub supercritical water has been reported for the reducing as readily available to acid enzymatic biomass hydrolysis. Accordingly, in this work, results batch semicontinuous lab subcritical experiments pea pot corn stover are discussed. Experiments were carried temperature range 250 300 °C, pressures up 3650 psi, residence times 30 minutes mode operation, or flowrates 12 mL/min operation. Produced assessed effluent each experimental run dinitrosalicilic method (DNS). A maximum total sugar (TRS) yield 21.8% was measured at 300°C, 15 minutes, 1:6 mass ratio. Semicontinuous showed TRS accumulated 19% 290 1500 flowrate 9 mL/min. The feasibility producing currently discarded through
