Klason lignin is generated by acid hydrolysis of woody materials with 72% sulfuric acid as a residue. This procedure is useful not only for the determination of lignin content but also for the production of sugar from woody biomass. In the acid saccharification process, Klason lignin is yielded as a byproduct. One of the key points in developing the acid saccharification process is to find the effective ways to utilize Klason lignin. In this review, the chemical conversion of Klason lignin into functional materials, such as surfactants, dispersing agents, bioactive agents was discussed.

There are some refineries equiped with a desalter which removes impurities contained in crude oil and reduces fouling and corrosion in refinery equipment.This article is based on the literatures, home and abroad, and summaries what impurities are contained in crude oil, what benefits can be gained by eliminating these, Particularly putting emphasis on the relation between the corrosion and desalting, what theories of desalting are, and what financial sawings are expected from desalting.Desalting is said to be good for reduction of fouling problem on equipments, but this is not always the case with prevention of corrosion. There is no agreed opinion about its effectiveness, for it depends on what type of crude oil is processed and what type of plants are installed in the refinery. Therefore, budget justification for desalting is the problem for each refinery to decide under consideration of its refinery situations.If, in the near future, desulfurization plant of residuum is forced to be installed from view point of air pollution, the two-stage desalting might be closed up.

Petroleum refineries discharge industrial waste such as waste oils, sludge, waste acids, waste alkalis and etc. However, thanks to the adoption of reuti-lization and recycling activities, petroleum refineries discharge only 329 thousand to 594 thousand tons of industrial waste per year and the ratio of discharged industrial waste from petroleum refineries have dropped to about 0.1 to 0.2 percent of all discharged industrial waste. Therefore, petroleum refineries haven't particular problems on industrial waste treatment.

The moisture reduction in fuelwood of Japanese cypress (Chamaecyparis obtusa) and evergreen oak spp. (Quercus glauca) was evaluated under some conditions differentiated in split sizes (one quarter or one eighth), drying area (paved or unpaved, roofed or unroofed), and season (winter or summer). Japanese cypress dried out more rapidly than oak. Splitting enables the acceleration of drying rate and size effect was more enhanced in oak with higher wood density. Any benefits of natural seasoning were realized within the first one or two month. Under natural seasoning with uriroofed condition, there was little benefit in longer drying period of fuelwood in terms of rainfall.

Primary aluminum consumes much energy in its production process-es leading a great quantity of emissions. In Japan, 99 ‰ amount of primary aluminum is currently imported from other countries. In this work, Global Warming Potential (GWP) and Acidification Potential (AP) values for primary aluminum ingot produced in Brasilia, Russia, Australia, Venezuela, U. S. A., Norway and Island have been investigated. The average GWP and AP values for Japanese import mixtures were calculated. The mini-mum GWP and AP values for primary aluminum ingot produced with best available tech-nology have also been estimated.It was found that GWP value of primary aluminum ingot produced in each country varied from 10.4 to 27.4 kg-CO2 equiv./kg, while AP value varied from 0.0172 to 0.135 kg-SO2 equiv./kg. The average GWP and AP values for Japanese import mixtures were 15.5 kg-CO2 equiv./kg and 0.0516 kg-SO2 equiv./kg, respectively. GWP value of primary alu-minum ingot could be reduced up to 6.32 kg-CO2 equiv./kg if it is produced with best available technology, and AP value could be reduced up to 0.0103 kg-SO2 equiv./kg. The environmental impact of primary aluminum ingot widely varies according to which coun-tries primary aluminum ingot was produced in and which technology was used in its pro-duction process.

Chongqing city, which is located in the southwest of China, suffers from acid rain damage caused by SO2 in coal combustion gas. Particularly, stoker type boilers in medium and small factories have no emission control facility in spite of using coal with high sulfur content (3-5%), so that a suitable countermeasure is required in angles of the cost, technological level and social conditions.We proposed a coal briquette combustion with the additive of limestone or slaked lime as one of the countermeasure. The possibility of coal briquette combustion methods was examined experimentally and compared with other methods from points of view of the cost and energy saving effect. The desulfurization rate of 70% was obtained in the briquette combustion method with the additive of limestone and 80% for slaked lime. Most of sulfur in the coal (both organic and pyritic) was trapped as gypsum anhydride (CaSO4). The desulfurization rate slightly depended on initial oxygen concentration in the supplied gas and size of limestone, while it was not influenced by briquetting pressure.The desulfurization cost of coal briquette was calculated as 20-30% of semi-dry or fluidized bed process. The briquette combustion method was expected to be effective in improving the human health and forest conservation in Chongqing city.

It has been developed a reliable methodology to be able to elucidate such thermal behaviors as a plasticity, and carbonization of coal based on the electric property. In particular, the temperature dependency of electric conductivity observed in the heating range from 400℃ to 700℃ was satisfactory demonstrated a leaner relationship on the Arrhenius's equation suggesting that it could provide the kinetic parameters such as activation energy which are able to elucidate the mechanism of the electric conductivity induced in the macromolecular network structure of coal during a pyrolysis.

From a view point of safety measure against the fire hazard involved with aircraft crash or ditch and singular hydrodynamical fluid motions in space flight and refueling with liquid rocket tankage, feasibility of gelled hydrocarbon fuels and propellants is discussed. It is concluded that O/W (oil-in-water) type gelled hydrocarbons are most promising as the safety fuels, resulting from a comparison in the rheological and combustion properties with the other gelled fuels; slurry, scaffold and thickened (highly viscous) ones. Physical properties and flammability of very high internal phase ratio gelled JP-4 and kerosene, ranged 96 to 99 vol% fuel content, and of N2H4/JP-4 gelled propellant developed by ISAS, Univ. of Tokyo and Mitsubishi Oil Company are described.

Antimatter possesses a highly condensed energy and the mass is completely converted to the energy by an annihilation reaction with matter. It has been considered as a science fiction that the space mission using such great amount of energy to other stars within the working lifetime of the crew.The p-p annihilation engine has been studied mainly in Europe and U.S.A.The reactor size is not so different from the main engine of Space-shuttle. At the present moment the antiproton is produced with use of a huge accelerator. In future, however, the optimization of production facilities enables the economical use of antiproton for a space vehicle. Nevertheless only a milligram of antiproton has energy of several-ten times as much as the conventional fuel.

Carbon Capture and Storage (CCS) technology, which is currently being developed around the world, could become a practical countermeasure to reduce emissions of the greenhouse gas. Depleted petroleum reservoirs and aquifer have been proposed as candidate sites of CCS. The long-term aim of this research is to establish a bio-technological system to convert geologically-stored CO2 into methane, as an energy resource. To develop a means for the conversion, we focus on technological application of a bio-electrochemical system using microbial catalyzed electrode (bio-cathode).

China has made every effort to increase the railway transport since the foundation of the Peple's Republic of China. In 1995, Chinese railways reached 54, 615 km.The transport distance is now 2.50 times longer than that in the foundation in 1949 and 1.12 times longer than that in the start of market-oriented reform and open-door policy in 1978.Ministry of Railways has succeeded in modernization of railways such as electrification, double tracking and making larger the freight car. China is expect to continue 8% economic growth rate for the next fifteen years. The production of coal is estimated at 1.4 billion tons in 2000, and 2.0 billion tons in 2010.The shortage of investment in railways will bring the shortage of the railway trans-port.I think that the tailway trasport, if it is insufficent to invest in railway transport would be bottole-neck of the production of coal in China. It is also necessary that both the waterway transport and road transport are expanded and strengthend by investments. Thus coal and railway are essential to Chinese economy.This paper expects that appropriate policy on the transport of coal is quite necessary for the sound economic growth in the future.
