Experimental study has been conducted on the occurrence of boilover processes in the pool fire. The flame and water temperatures and optical energy were measured during the pool burning of hydrocarbon with high boiling point. n-Hexadacane layer with emulsion layer were composed on the water sublayer in the cylindrical container. Attention was mainly paid for temperature conditions at the occurrences of boilover in the pool burning processes. It is concluded that the time for extinguishment become to shorten by existing of emulsion layer, in which boilover processes were largely changes. Occurrence conditions of boilover were also discussed by time histories of flame, emulsion layer and water sublayer with optical energy from pool fire.

<p>We investigated a method of using sewage as liquid fertilizer for mass production of fuel crops. At the sewage treatment plant in Shizuoka Prefecture, when root-zone irrigation was performed with multi-layer cultivation of sweetpotatoes with sewage after removal of contaminants and solids, fine roots grew on the liquid surface and grew using nutrients in sewage. It was found that the productivity was more than three times that of ordinary soil cultivation.</p>

<p>As one of the Holy Grail reactions in C1 chemistry, direct selective oxidation of methane to methanol under mild and non-harsh conditions remains a big challenge. Hydroperoxide (H<sub>2</sub>O<sub>2</sub>), as a primary oxidant, applied widely in the lowtemperature direct selective conversion of methane to methanol. Moreover, the hydrogen and oxygen mixture gas achieves better reaction activity and higher methanol selectivity than H<sub>2</sub>O<sub>2</sub> when using palladium-gold (Pd-Au) bimetallic nanoparticles as the catalyst. In this paper, we studied the key roles of the physical and chemical characteristics of Pd-Au nanoparticles in this direct selective oxidation reaction with hydrogen and oxygen as the oxidant at 50°C. For further clarifying the physical and chemical characteristics of catalysts, X-ray powder diffraction (XRD), X-ray photoelectron spectroscopy (XPS), Hydrogen-Temperature-programmed reduction (H2-TPR), and CO pulse adsorption measurement (CO-PULSE) analysis methods are also measured.</p>

Ammonia is focused on as a no carbon fuel, and the design of the fuel cell vehicle with onboard devices to generate hydrogen from ammonia is performed. The ammonia has higher hydrogen content by percentage than that of methanol or ethanol, and can be liquefied at a normal temperature and a pressure of 0.84 MPa. Therefore the ammonia has a possibility as a new energy, because it can be obtained from biomass energy such as urea.

<p>These days, the amount of domestic waste is decreasing in association with the depopulation and the need for small scale garbage disposal plant is growing among local governments. In this research, we imitated the power generation from biomass resources that includes domestic waste. We gasified woody biomass by using mixed gas of nitrogen as an oxidizing agent and measured the composition of the bio-syngas, temperature in the reactor and so on. Consequently, the bio-syngas produced low heat value. It is believed that the carbon conversion efficiency and the cold gas efficiency decreases when the flow rate of an oxidizing agent increases or the quantity of supplied oxygen into the reaction field decreases.</p>

<p>Woody biomass of various moisture content for gasification of woody biomass is used. But there are few previous studies on woody biomass with moisture content of 15% or less. Therefore, we made a small scale gasifier and studied the effect of moisture content of woody biomass on gasification by using woody biomass reduced moisture content. It was found that carbon conversion efficiency and cold gas efficiency can be high depending on the moisture content.</p>

<p>Pyrolysis and combustion process of Mongolian Pine tree sawdust have been investigated by the isothermal thermogravimetric technique, at several different operating temperatures using the vertical fixed bed reactor. Gas chromatography analysis was employed to characterize the composition of evolving gas in samples during the pyrolysis process. Thermal degradation results showed that pine sawdust mainly devolatilized around 300-450°C temperatures with total volatile yield about 78%. When it is comparing with the Mongolian brown coals, devolatilization was higher at above 600°C (the volatile yield was 39-54% for all brown coals) than lower temperatures (7-32% at 600°C˂). The reaction kinetics activation energy (<i>Ea</i>), pre-exponential factor (<i>A</i>) were determined using first-order method for pyrolysis process. The apparent activation energy of Pine sawdust is 29.3 kJ/mol during pyrolysis process at range temperature of 600-900°C. The main evolving gaseous products during pyrolysis were H<sub>2</sub>, CH<sub>4</sub>, CO, CO<sub>2</sub>, and their yields were relatively each pyrolysis temperatures.</p>

Electroactive Polymer Artificial Muscle has two operating modes: an actuator mode and a generator mode. The actuator mode uses planar deformation of elastomers resulting from the combination of an electrostatic attractive force between electrodes on each side of the film, and a repulsive force within each electrodes, both being generated by a voltage difference applied between the two electrodes. The EPAM generator mode uses the reverse process of the actuator mode, storing the increase in electrostatic energy originating from the deformation of EPAM by an external force. Because the energy for each cycle of deformation does not strongly depend on deformation speed or frequency, a generator working under this phenomenon can harvest energy from a variety of low-frequency natural sources, such as the up and down movement of waves, the gentle movement of rivers, and the movement of human beings and animals. The movement of vehicles and buildings may also be used to generate energy.

In this study we were carried out the LCA of consumer's behavior level for LCT training. And we calculated the environmental load of the consumer behavior. There are big differences of the environmental load of each behavior by setting of the condition because consumer behaviors have variety. So, we calculated the consumer behavior on the condition that it was average and representative as possible. However, in order to lead to environmentally friendly behavior, consumer behavior was also calculated in different conditions that may be affected. For example the behavior of "to take a meal", we calculated about 100 Japanese typical menus. And in order to understand the differences in the environmental load of eco cooking, we calculated several type of cooking way on same menu.
