Abstract: Up to now, the only solution for utilization of solid wastes including biomass as energy resources is to incinerate them and to use the produced heat directly or to convert the produced heat into electric power employing boilers/steam turbines. Tokyo Institute of Technology is developing and commercializing total technologies to convert unutilized resources such as solid wastes and biomass into high value added energy resources (solid fuel, gaseous fuel, liquid fuel and electric power) by combining various technologies which have been jointly developed with many companies. This presentation focuses on R&D and successful commercial applications of these technologies. The content of the technologies are as follows.
・Solid Fuel Production Technologies: The hydrothermal treatment technology can convert unutilized resources with various shapes, heating values and moisture contents into uniform dry powder-like solid fuels with the heating value equivalent to coal.
・Liquid Fuel Production Technologies: Gasoline or diesel equivalent fuel oils can be produced from waste plastics by employing the pyrolytic reforming oil production technology and from waste cooking oils or plant oils by employing the dry-type alkali catalyst bio-diesel production technology. The emulsion fuel which is a mixture of oil and water can reduce emissions as well as improve thermal efficiency of boilers.
・Gasification and Power Generation Technologies: The gasification technologies can produce low calorific value gases from solid fuels by employing pyrolysis and reforming technologies. Electric power can be generated from this low calorific value gases by employing internal external combustion engines.
