摘要： PROBLEM TO BE SOLVED: To provide a process for preparing a biodegradable polyester which can remove the heat generated in ring-opening polymn. to regulate the temp. in the reaction system, can react a high-viscosity polymer and can stably prepare a high-mol.wt. biodegradable polyester free from coloring. SOLUTION: At least one dimer cyclic ester of a hydroxycarboxylic acid and/or at least one lactone are continuously fed from one end of a tubular reactor provided with a jacket to conduct ring-opening polymn., while the resultant polymer is withdrawn from the other end of the reactor. A heat transfer medium for the regulation of the temp. is passed through the jacket. Pref., initial polynm. is carried out in an agitation tank type reactor provided with an agitating element, and the resultant polymn. mixture is introduced into the tubular reactor to further conduct the polymn. A multi-tubular heat exchanger is pref. as the tubular reactor. This process is suitable for the preparation of a polylactic acid by ring-opening polymn. of a lactide.

摘要： PROBLEM TO BE SOLVED: To provide a method for stability producing a modified biodegradable polyester in high efficiency. SOLUTION: In the polymerization of an aliphatic polyester, at the late stage of the polymerization reaction or after the polymerization reaction, a modifier is added to the reaction system while keeping molten state. In the case of polymerization of lactic acid, either a ring opening polymerization of a lactide or a direct condensation through dehydration of lactic acid is preferred. The modifier is added after more than 70% of the polymerization raw material is reacted. Aliphatic polyester, alcohols, carboxylic acids, lactic esters, acid and water are preferred as the modifier. This method is capable of effectively producing two or more kinds of biodegradable polyester suppressing the degradation of the modifier at the minimum level.

摘要： PURPOSE:To reduce the capacity of a liquid nitrogen storage facility and the number of times for replenishing liquid nitrogen by using a pressure-swing- adsorption(PSA) nitrogen generator provided within a fuel cell power system, in supplying part of the nitrogen used in the system. CONSTITUTION:A fuel cell system is provided with a liquid nitrogen storage tank 4a into which liquid nitrogen, which is used to supply purge nitrogen gas at the start and stop of the system and to supply sealing nitrogen gas during operation of the system, is supplied. A PSA nitrogen generator 12, etc., is provided within the system to supply part of the nitrogen used. Therefore, the capacity of the liquid nitrogen storage facility and the number of times for replenishing the liquid nitrogen can both be reduced, resulting in an enhanced economy of the nitrogen facility of the fuel cell power system. Oxygen that is generated as nitrogen is generated within the system by the generator 12 is supplied to the reforming burner of the power system.

摘要： PURPOSE:To make the liquefying and separation of air efficient by separating the mixture of gas and liquid by a gas and liquid separator into vapor rich in nitrogen and condensed liquid rich in oxygen. CONSTITUTION:Vapor, fractionated in a lower pressure tower 1 and supplied to a lower evaporator 31a as a heat source for evaporation after being introduced out of the top of a lower pressure tower 1, becomes the mixture of gas and liquid after being condensed as the result of heat exchange, then, is supplied to a gas and liquid separator 4. The mixture of gas and liquid is separated in the gas and liquid separator 4 into vapor, rich in nitrogen, and condensed liquid, rich in oxygen. The vapor, rich in nitrogen, is supplied to an upper pressure tower 2 whereby the inside of the upper pressure tower 2 becomes a condition rich in nitrogen and nitrogen is taken out from the top of the upper pressure tower 2 as vapor while liquefied air, rich in nitrogen, is taken out of the bottom and is supplied to the upper tower 32 of a low pressure tower 3. According to this method, fractionating operation becomes favourable and efficient liquefying and separating treatment of air can be effected.

摘要： PURPOSE:To flow ascending gas at center part and to make stability and promote efficiency of the operation by charging coke from a charging chute at the center part arranged with slope under suitable condition at the time when the previous piling layer at the center part in a blast furnace reaches to the optimum height. CONSTITUTION:The coke is exclusively charged into the center part in the blast furnace from the charging chute at the center part arranged with slope so as penetrating furnace wall at the top part in the blast furnace and directing to the center part. Then, the setting condition of the charging chute and interrelation between height of the previous piling layer at the center part and the dropping piled shape of the above charging coke formed on this are beforehand grasped. Further, the height of the previous piling layer in the center part at the time of the actual operation is measured with horizontal sonde and vertical sonde. At the time when this height reaches to the optimum height, based on the above setting condition and the interrelation, charge of the coke at the center part is exclusively executed. By this method, the coke is suitably piled into the center part and the ascending gas is flowed at the center part in the blast furnace and the blast furnace operation is made to stability and promoted to efficiency.
