Thermo-physical properties of several pretreated agricultural residues for photo-fermentation bio-hydrogen production were investigated.
Different model-free methods were utilized to calculate the activation energy of each selected sample.
Corncob had the lowest residue content, peak temperature and the lowest activation energy.
Thermogravimetric method elucidated the thermos-physical of ARPs which related to the bio-hydrogen production.
The lower residue content and activation energy is, the more hydrogen-production potential will be.
