摘要： PURPOSE:To miniaturize the size of the titled device and simplify the apparatus by forming a reaction tank in a horizontal type, providing diaphragms at the central portion thereof, arranging a heat storage reaction tank and an absorption reaction tank at both right and left hands, and using a space formed by the upper end of a section wall and a vessel as a vapor passage. CONSTITUTION:The central portion of a vessel 500 is perpendicularly partitioned by diaphragms 600 and the upper part of the vessel 500 is not partitioned but form a vapor passage 810. One part sectioned by said diaphragm is used as a heat storage reaction tank 300 and another is used as an absorption reaction tank 200l. In the heat storage reaction tank 300, a plurality of evaporation absorbing members 135 formed by two opposite hydrophobic porous materials 130 and having an opening part 131 on its upper surface, a sealing member on its end surface and having an enclosed bottom surface, are arranged with suitable intervals. A large number of heat transfer pipes 110 for heating and cooling are arranged in said intervals. The heat storage reaction tank 300 is formed by providing the above described units. On the other hand, the absorption reaction tank 200 has the same construction as described before.

摘要： PURPOSE:To easily inject a modifier into a high-pressure system and to continuously introduce a solid raw material into an extraction vessel by mixing the raw material and the modifier and injecting the mixture into the extraction vessel. CONSTITUTION:When a modifier is added into a supercritical gas and a material to be extracted is decomposed, a raw material contg. the material to be extracted and a solvent as the modifier are mixed in a mixing vessel 10, the mixture is forced by a pump 20 into an extraction vessel 16 which is filled with an extractant through an injection pipeline 18 and the material to be extracted in the raw material is eluted into the extractant. Then the material to be extracted and the solvent are separated from the extractant and recovered in a separation vessel 32 and a vessel 42 for recovering the solvent as the modifier. Consequently, the solvent as the modifier can be easily injected into a high-pressure system and the solid raw material can be continuously introduced into the extraction vessel 10.

摘要： PURPOSE:To operate the extraction separating device continuously utilizing super critical fluid by supplying the substance to be extracted and continuously discharging residual matter. CONSTITUTION:After the super critical extraction solvent is contacted with the substance to be extracted supplied from the supply unit 9 in the extraction tank 8 to solve and extract the objective component out of the original substance, said component is led into the separation tank 12 to separate the objective component, which is stored in the extraction tank 13. Further, the new substance to be extracted supplied from the material storage tank to the storage tank for the substance to be extracted is stirred and mixed with the residue of the substance, the whole or part of which is extracted into the solvent, returning from the extraction tank through the pressure reducing device 21 and the separation device 22. Then the pressure of said mixture is raised to the specified pressure level and is effused out drop-wise into the extraction tank 8 through the effusion tube installed in the extraction tank 8.

摘要： PURPOSE:To easily perform not only the recovery of a stock material residue and an extracted substance but also the washing of an inner container and to prevent the clogging of the pipings attached to an extraction tank and a separation tank, by respectively storing the stock material residue and the extracted substance in the inner containers provided in both tanks in a detachable manner. CONSTITUTION:Carbon dioxide is introduced into the stock material in the inner container 11 of an extraction tank 11 in a state of a supercritical gaseous fluid to be contacted with the stock material and the component to be extracted in the stock material is dissolved in and extracted with the gas while the residue of the stock material is left in the inner container 11. Thereafter, the supercritical gas is introduced into the inner container 21 of a separation tank 2 and the density of the gas is reduced to separate the extracted substance which is, in turn, stored in the inner container 21. The supercritical carbon dioxide separated in the separation tank 2 is introduced into the inner container 31 of an evaporation tank 3 to be separated into carbon dioxide and the extracted substance. After extraction operation was completed, operation is stopped and the inner containers 11, 21, 31 are taken out of the system and, after the stock material residue and the extracted substance were recovered, said inner containers are washed.

摘要： PURPOSE:An extraction raw material such as animal or vegetable substance is made to contact with a supercritical gas together with an extraction assistant consisting of an alcohol or an organic solvent to effect the extraction of the extractable substance in the supercritical gas and the extractable substance is separated by varying the pressure and temperature of the supercritical gas. CONSTITUTION:The extraction raw material is mixed with the extraction assistant (e.g. alcohol, organic solvent, etc.) in the stirring tank 29, and the mixture is heated with the heat exchanger 31 and supplied to the extraction tank 27. Separately, liquid carbon dioxide is treated with the booster pump 25 and the heat-exchanger 26, and the obtained supercritical gas is introduced into the extraction tank 27 to effect the extraction of the extractable substance with the supercritical gas. The supercritical gas containing the extracted substance is introduced into the separation tank 33, and only the extracted substance is separated under a prssure 1.0-2.0 times the critical pressure at a temperature 1.0-1.2 times the critical temperature. After the separation treatment, the gas is introduced into the extraction assistant-separation tank 35. The carbon dioxide gas is circulated through the valve 36 and the extraction assistant is reused after separation the low-boiling impurities in the separation tank 37. EFFECT:The extraction assistant can be dissolved in the supercritical gas at an arbitrary ratio and an extractable substance free of extraction assistant can be produced.

摘要： PURPOSE:To make the weight and size of a fuel cell small and the thickness of the stack of the unit cells of the fuel cell uniform, by using end plates of the same dimensions as the outline of each unit cell to push and clamp the unit cells together. CONSTITUTION:After unit cells 20 are loosely stacked together, the pushing force of a pressing machine or the like is used to push the unit cells at the surface pressure of 2 to 10kg/cm to prevent the leak of gas and liquid from the unit cells and keep the electric resistance of the joint of the unit cells from becoming high. The pushed unit cells 20 are pinched together with electrically- insulating end plates 19 between end plates 18 of the same dimensions as the outline of each unit cell and clamped thereon by bands 26 secured to the end plates 18 by screws 27. As a result, the weight and size of a fuel cell are made small. Besides, the stack of the unit cells is uniformly pushed to make the connection of an electrolyte film and electrode plates uniform to enhance the performance of the fuel cell.

摘要： PURPOSE:To enhance the extractive decomposition capability and extraction velocity by increasing the pressure of a solvent and then increasing the temp. easily to form a large amt. of a supercritical solvent which is used for extraction. CONSTITUTION:Gaseous carbon dioxide to be used as an extracting solvent flowing from a tank 20 is cooled by a liquefier 21 to form liquefied carbon dioxide. The liq. is filtered in a filter 23 to remove foreign matter. Then the pressure of the liq. is increased to above a critical point by a pump 24 and the temp. is increased by a heat exchanger 25 to a supercritical state to obtain a supercritical extracting solvent. The supercritical liquefied carbon dioxide is brought into contact in an extraction tank 26 with substances to be extracted supplied from a device 27 for supplying the substances to be extracted and a specified component is dissolved and extracted from the substances to be extracted. The liquefied carbon dioxide wherein the substances to be extracted are dissolved is introduced from the extraction vessel 26 to a separation vessel 30 to separate the desired specified component. The separated specified component is stored in a selection vessel 31 and selected.
