| Research Abstract |
The fundamental study for developing a safe handling system for waste biomass fuels was studied; especially for the prevention of fires and explosions associated with refused derive fuels (RDF). The RDF hydrogen production ability was affected by pH, moisture and ambient temperature. The microbial colony count method revealed that aerobes occupied a dominant in RDF on the 2nd or 3rd day from the beginning, whereas anaerobic occupied a dominant hereafter. Bacillus sp. was superior to Clostridium sp. in Kuwana, whereas Clostridium sp. was superior to Bacillus sp. in Sakura after 3 days of cultivation. Scale effects on the temperature rise of RDF due to biological activities were examined by three different amounts of RDFs. It was reported that the higher amount of RDF, the higher the maximum temperature obtained after 50 hours to 85 hours cultivation was.
