Comparing the Bio-Hydrogen Production Potential of Pretreated Rice Straw Co-Digested with Seeded Sludge Using an Anaerobic Bioreactor under Mesophilic Thermophilic Conditions

Hydrogen is regarded as the potential bearer of energy of the future. Solar hydrogen is the hydrogen produced using renewable energy, particularly solar energy [15,8]. The availability of water and hours of sunshine make Algeria a place of choice for solar hydrogen production. In this work, solar hydrogen production by electrolysis of water is considered. The required energy for water dissociation is supplied by a photovoltaic system. A design and operation study of a photovoltaic system has been done for three different regions in Algeria. The production potential is highly significant particularly in the south parts of this country.

Central Composite

Response surface methodology (RSM) with central composite design was adopted to investigate the optimum condition for carbohydrate released from hydrothermal pretreated sludge in an autoclave used for WAO (wet air oxidation). Temperature, time and stirring rate were chosen as variables. The maximum carbohydrate release (1356.8 mg/L) was estimated at the temperature of 161.2 °C, the time of 48 min and the stirring rate of 661 r/min. This statistical method could precisely optimize reaction conditions and predict the experimental data. Only 11.2 mL methane was generated with little hydrogen production of raw sludge. In contrast, hydrogen production potential of 25 mL was reached by using supernatant as substrate with a COD removal of 78.14%. Hydrogen yield was increased from 0.13 mL/g-VS (raw sludge) to 13.16 mL/g-VS (supernatant of pretreated sludge).
