  • Publication number: 20060185516
    Abstract: A system and a method for recovery of carbon dioxide in exhaust gas, wherein a liquid absorbent (116) jetted from a liquid absorbent jetting part (101) comes into gas-liquid contact with exhaust gas (114) flowing through a packing (102) from the lower side to the upper side to absorb the carbon dioxide contained in the exhaust gas (114). The flow of the liquid absorbent (116) in a deposition vessel (11) conditioned to a specified pH value is stopped to deposit insoluble compounds as the reaction product of the liquid absorbent (116) against the carbon dioxide, and the carbon dioxide is collected as the insoluble compounds. Thus, the carbon dioxide can be removed from the liquid absorbent which absorbed the carbon dioxide without using steam from a power generating boiler.

  • Publication number: 20040017647
    Abstract: An electrical double-layer capacitor has a construction wherein a pair of positive and negative polarizing electrodes whose chief constituent is active carbon laminated (or coiled) in a condition with a separator sandwiched therebetween and with their outsides held by respective aluminum collection electrodes are accommodated in a case made of metal etc. in a condition impregnated with electrolyte using propylene carbonate as solvent. The polarizing electrodes have a solid-state structure wherein the active carbon particles are the chief constituent (first substance) and these active carbon particles 3 are connected in network fashion by a second substance such as for example nano-size carbon black which is of higher electrical conductivity than the active carbon and of smaller size than the active carbon particles.
