Food Waste Digestion for Hydrogen Production Using a Single-Phase Reactor

Abstract:

A single-phase reactor was applied to food waster digestion for hydrogen production in order to test its feasibility. Different solid retention time (SRT) and pH adjustment modes were tried in a series of semi-continuous experiments. The results showed that it was necessary to take some precautions including a long SRT and a proper pH adjustment mode so as to avoid the excessive acidification in single-phase digesters. When lime milk was added into the digester to adjust pH to about 7 once a day, the food waste digester, which had a SRT of 20 days and a feed concentration of 4%, can produce hydrogen steadily. The hydrogen content was 27.6-51.3% and the degradation rate of food waste organic matter was 54%.
