Beschreibung
Zusammenfassung:	[PROBLEMS] A high-pressure apparatus for forming fine bubbles of carbon dioxide is provided with which carbon dioxide can be efficiently mixed in the form of fine bubbles with a solvent at a high rate under high-pressure conditions. [MEANS FOR SOLVING PROBLEMS] The apparatus includes a main pipe line (30) in which a solvent flows at a given high velocity and a supply pipe line (31) for the carbon dioxide, the pipe line (31) having been fitted from outside to the whole periphery of the pipe line (30). The pipe line wall which separates the solvent from the carbon dioxide has fine holes (30a) formed therein. The carbon dioxide is caused to come into the solvent while being formed into fine bubbles by the shear force of the solvent flowing in the main pipe line (30).The flow velocity of the solvent and the diameter of the fine holes are set so as to result in a Weber number (We) of 10 or larger.
