摘要:
A novel method of biomass processing, in which while carrying out efficient fermentation of biomass, energy can be recovered without the use of plants and in which after the biomass processing the concentration of organic matter in waste liquid can be reduced. There is provided a method of biomass processing, comprising carrying out a hydrogen fermentation of biomass with the use of a hydrogen producing bacterium to thereby recover hydrogen. Further, a fermentation liquid occurring after the hydrogen fermentation is subjected to methane fermentation with the use of a methane bacterium to thereby recover methane. In this instance, at least an organic acid is contained in the fermentation liquid.

It is intended to realize storage and transportation of large amounts of energy and to carry out storage or supply of energy in conformity with fluctuation of natural energy. There is provided an organic hydride synthesizing apparatus capable of hydrogenation reaction between an unsaturated hydrocarbon and hydrogen in the presence of a catalyst to thereby accomplish synthesis of an organic hydride, which organic hydride synthesizing apparatus comprises a catalyst, heating means (3a) for heating the catalyst, hydrogen supply rate detection means (25) for detecting the rate of hydrogen supply to the interior of the apparatus, and control means (31),(32),(33) for in accordance with the supply rate, controlling the rate of unsaturated hydrocarbon fed, the rate of product recycled and the temperature of the catalyst.
摘要:
This electric artificial larynx 1 comprises a sound source generating unit 3 which is held by interposition means 2 attached directly or indirectly to the human body 10 and can be always placed near the cervical region 10a and a portable controller 4 which is separated from the sound source generating unit 3 and operates the sound source generating unit 3. The controller 4 preferably comprises a control signal generating unit which includes a sensor for detecting ID biological information or a switch 12 for supplying a signal and a control unit 16 which drives and controls the sound source generating unit 3 in response to a signal from the control signal generating unit and has a power source unit 15 for supplying power to the sound source generating unit 3. The sound source generating unit 3 may be caused to output a sound using sound source data based on the voice data of an operator before an operation for removing the larynx, or storage means for storing sound source data for singing a song may be provided in the controller 4 detachably.
