ジャーナル フリーUntil recently, the energy problem in Japan had been the problem of how enough energy could be supplied to various sectors in society under Japan's conditions of only a few energy resources existing within its territory. However, recently new environmental and social conditions are arising. These new conditions strongly affect not only concrete measures for resolving the energy problem but also the characteristics of the energy problem itself. Nowadays, it seems to be impossible to resolve the energy problem without taking these conditions into consideration. For this reason, a new framework, which enables various social values to be reflected in concrete measures, is urgently needed to resolve the energy problem.抄録全体を表示PDF形式でダウンロード (1147K) -

ジャーナル フリーA fuel spray mixture suffered by partial oxidation through a catalytic honeycomb was studied experimentally. The palladium catalyst supported on the cordierite honeycomb monolith was used. Kerosene vapor was introduced into the ca talytic honeycomb. The parabolic shape blue flame that was supported on the catalytic honeycomb was formed even if the equivalence ratio of the mixture was less than stoi-chiometry. To clarify a reaction process in an combustible gas between the honeycomb and the blue flame, CO, HC (C1-C7) and NO were analyzed. When blue flame appeared, CO and HC concentration were increased between the honeycomb and flame. Further, high molecular species (C8-C15) in the combustible gas were trapped by the water-cooled condenser system and they were analyzed by the gas chromatograph and mass spectroscopy. Spontaneous emission spectra from the blue flame were measured. Strong spectral peaks of OH, CH and H2O radicals were observed in it. To compare with the spectra, spontaneous emission spectra from the pre-vaporized flame of kerosene mixture were measured.抄録全体を表示PDF形式でダウンロード (2119K) -

ジャーナル フリーA mathematical model of SO2 capture by single limestone particle under pressurized fluidized bed combustion conditions was proposed. In the present model, particle attrition was taken into consideration. Effect attrition mode, i.e. continuous attrition or intermittent attrition, on overall reaction rate, overall reaction order with respect to SO2 concentration, and maximum utilization of solid were evaluated. Attrition mode had a great influence on sulfur capture behavior even if the average attrition rate was the same. Attrition mode was found to be very important to make a model of SO2 capture in pressurized fluidized bed抄録全体を表示PDF形式でダウンロード (1192K)
