This invention concerns an apparatus and a method for producing carbonated water capable of obtaining high concentration carbonated water effectively. Carbon dioxide gas is passed through a first carbon dioxide gas dissolver composed of a membrane module to be dissolved in water and the carbonated water passing through the first carbon dioxide gas dissolver is passed through a static mixer, which is a second carbon dioxide gas dissolver. Consequently, a high concentration carbonated water can be obtained remarkably, effectively and easily with a simpler structure than conventionally.

A treatment method capable of regenerating new blood vessels at an affected site of a peripheral blood vessel that is highly safe with respect to the human body and is easily performed. More specifically, a vascularization therapy that increases the number of newly formed blood vessels of an affected site by immersing in carbonated warm water having a carbon dioxide concentration of 700 ppm or more and a water temperature of 33 to 42° C. A vascularization therapy that increases the number of vascular endothelial cells in tissue of an affected site by 1.5 times or more and that increases the number of endothelial precursor cells in the peripheral blood at an affected site by 1.1 times or more by immersing the affected site of a peripheral blood vessel in the aforementioned carbonated warm water.

The present invention provides: a palladium-containing supported catalyst which is used for producing an α,β-unsaturated carboxylic acid from an olefin or an α,β-unsaturated aldehyde in high selectivity; a method for manufacturing the catalyst; and a method for producing an α,β-unsaturated carboxylic acid in high selectivity. In particular, the present invention resides in a method for manufacturing a palladium-containing supported catalyst for producing an α,β-unsaturated carboxylic acid from an olefin or an α,β-unsaturated aldehyde, comprising the step of reducing palladium oxide contained in a catalyst precursor wherein at least the palladium oxide is supported on a carrier. By using such a palladium-containing supported catalyst, an α,β-unsaturated carboxylic acid is produced through liquid-phase oxidation of an olefin or an α,β-unsaturated aldehyde with molecular oxygen.

摘要:
Hot water is pumped by a suction pump and introduced into a carbon dioxide (CO2) gas dissolver through solution flow rate adjusting means and then poured into a bath. The CO2 is introduced into the CO2 gas dissolver through gas flow rate adjusting means, and the quantity of bubbles in an artificial carbonated spring in a take-out pipe is measured. The solution and gas flow rate adjusting means are controlled via a control device using a relationship expression between a preliminarily set quantity of bubbles and carbon dioxide concentration to obtain a desired concentration of carbon dioxide gas in the carbonated spring. Since the carbon dioxide gas flow control means is provided between the carbon dioxide gas dissolver and a carbon dioxide gas supply source, a high concentration carbonated spring can always be manufactured, even if the pressure of supplied carbon dioxide gas changes or membrane permeation changes.

Hot water (12) in a bath (11) is pumped up by a suction pump (9) and introduced into a carbon dioxide gas dissolver (7) through solution flow rate adjusting means (14) and then, poured into the bath (11). Carbon dioxide gas supplied from a carbon dioxide gas cylinder (1) is introduced into the carbon dioxide gas dissolver (7) through gas flow rate adjusting means (5). At this time, the quantity of bubbles existing in artificial carbonated spring in a take-out pipe (15) is measured with a measuring device (13), and the solution flow rate adjusting means (14), gas flow rate adjusting means (5) and the like are controlled by means of a control device (16) using a relational expression between a preliminarily set quantity of bubbles and carbon dioxide concentration to obtain a desired concentration of carbon dioxide gas in carbonated spring. Because the carbon dioxide gas flow control means (5) is provided between the carbon dioxide gas dissolver (7) and a carbon dioxide gas supply source, carbonated spring of a high concentration can be always manufactured even if the pressure of supplied carbon dioxide gas changes or the permeating performance of a membrane changes.

摘要:
A carbonate spring producing system includes a gas-liquid separator which is connected on the downstream side of a carbonic acid gas dissolver which connects to a carbonic acid gas supply means and hot water supply. A liquid lead-out pipe is connected to the gas-liquid separator. Preferably an un-dissolved carbonic acid gas lead-out pipe is connected on the upstream sides of the gas-liquid separator and the carbonic acid gas dissolver. The un-dissolved carbonic acid gas lead-out pipe includes a control valve, a compressor, and a liquid level detection means. The control valve controls a flow rate of un-dissolved carbonic acid gas from the gas-liquid separator. An amount of un-dissolved carbonic acid gas in the gas-liquid separator is monitored, so that the un-dissolved carbonic acid gas in the hot water can be separated and removed by the gas-liquid separator. The separated and removed un-dissolved carbonic acid gas can be re-dissolved.
