摘要： A contamination purification system which can be installed in a narrow space to efficiently treat soil contaminated with a volatile organic compound, even when it is at a relatively low concentration, without needing a large-scale purification unit, and can effectively utilize the recovered volatile organic compound by its combustion/electric power generation unit. More particularly, a contamination purification system for purification of an area contaminated with a volatile organic compound, which is composed of an extraction well located in the contaminated area, gas suction/exhausting unit for extracting the volatile organic compound from the extraction well, vapor liquid separator for separating water accompanying the extracted volatile organic compound, and combustion/electric power generation unit for transforming energy produced by combusting the separated/recovered volatile organic compound into electric power, wherein the electric power produced by the combustion/electric power generation unit is used as a power for driving the contamination purification system.

摘要： A combustion method for an internal combustion engine which prevents the occurrence of engine knock and improves fuel consumption and economy, by spray injecting part of the fuel used in one cycle into a combustion chamber, performing preliminary combustion of a diluted air-fuel mixture below combustible limits at a temperature lower than the self-igniting temperature of the fuel, then injecting the remaining fuel into the combustion chamber, and performing main combustion by flame propagation using spark plugs as ignition sources. Accordingly, the combustion method for an internal combustion engine of the present invention can attain stable combustion even at high air-fuel ratios and makes high compression ratios possible.

摘要： There is disclosed a catalyst which hydrotreats hydrocarbons without need of presulfiding. The catalyst comprises a carrier of an inorganic oxide containing a sulfurizing agent and a water-soluble compound of two metals one of which belongs to the Group VI of the Periodic Table, while the other belongs to the Group VIII. The carrier has pores in which a precursor of a sulfide is formed. The coordination number of the closest Group VI metal found from the radial distribution function around the Group VI metal is less than 0.25. The function is obtained from the Fourier transform of the extended x-ray absorption fine structure of the precursor.
