摘要:
The present invention provides an apparatus, and a method for the regeneration of spent wet active carbon, which apparatus comprises a drier for substantially drying the spent carbon, a heating furnace provided with at least one burner and at least one duct, and a regeneration chamber consisting of at least one set of inner cylinder and outer cylinder installed concentrically and vertically inside said heating furnace to penetrate the top and bottom walls of the furnace, wherein said inner and outer cylinders have respectively a multiplicity of holes penetrating the side walls thereof, said inner cylinder is connected with a supply tube for a regeneration gas capable of effecting regeneration of the dried carbon-to-be-regenerated upon contact therewith, the upper end of said outer cylinder is connected with said drier so as to receive said dried carbon therefrom while the lower end thereof forms an outlet for the regenerated carbon, and said duct is connected with the drier so as to facilitate direct or indirect utilization of the sensible heat of the combustion exhaust gas in drying the spent active carbon.

The apparatus comprises an outermost, an intermediate, and an innermost compartment, the outermost compartment being provided with burners, activated carbon being supplied into, treated in, and removed from the intermediate compartment, and there being communication for gas between the three compartments. In revivification by the direct heating process, reactor gas is supplied into the outermost compartment, heated by the burners, passed into the intermediate compartment to contact the activated carbon being treated, and is then passed into the innermost compartment and exhausted therefrom. In revivification by the indirect heating process, reactor gas is supplied into the innermost compartment, passed into the intermediate compartment for treatment of activated carbon, and then passed into the outermost compartment and is exhausted therefrom, the innermost and intermediate compartments and elements therein being indirectly heated by the burners of the outermost compartment.
摘要:
The present invention provides a double-cylinder type apparatus for the regeneration of active carbon, which comprises a heating furnace provided with at least one burner and at least one annular regeneration chamber composed of at least one set of an inner cylinder and an outer cylinder installed concentrically inside said heating furnace, said outer cylinder having a plurality of holes penetrating the side wall thereof, wherein the spent active carbon is supplied to the upper part of said annular regeneration chamber and the regenerated carbon is to be taken out at the lower part of the same. The heating of said annular regeneration chamber from the side of said inner cylinder is performed either by introducing the flue gas arising in said heating furnace into the inner cylinder or by providing at least one burner within said inner cylinder and utilizing the combustion gas from said burner. The spent active carbon can be regenerated by subjecting the same to the process comprising drying, calcination and reactivation by the use of the flue gas.
摘要:
The present invention provides an apparatus for the regeneration of wet spent active carbon devised so as to bring the active carbon supplied from a hopper into contact with a reaction gas generated or heated to high temperature in a furnace, wherein an exhaust duct for the high-temperature exhaust gas from the furnace is installed penetrating the hopper in order to heat the active carbon descending therein and a condensate collecting header for discharging water separated from the active carbon is disposed at the lower part of the hopper.
摘要:
The present invention aims to provide an amino acid-containing granule preparation improved in the ease of taking medication than conventional products, which disintegrates rapidly. The amino acid-containing granule preparation of the present invention containing granules having a maximum particle size of substantially not more than 1000 μm and a bulk density of not less than 0.57 g/mL markedly improves ease of taking medication without impairing disintegration property, as compared to conventional amino acid-containing granule preparations.
摘要:
A tablet composition containing N-(trans-4-isopropylcyclohexanecarbonyl)-D-phenylalanine and low substituted hydroxypropylcellulose is disclosed. This tablet composition is rapidly disintegrated in the stomach after the administration and absorbed without being influenced by meals to inhibit the rise of the blood sugar levels of diabetics after meals.

摘要:
A tablet composition containing N-(trans-4-isopropylcyclohexanecarbonyl)-D-phenylalanine and a disintegrant, selected from a low substituted hydroxypropylcellulose, sodium carboxymethyl cellulose, calcium carboxymethyl cellulose and sodium croscaramellose sodium, is disclosed. This tablet composition is rapidly disintegrated in the stomach after the administration and absorbed without being influenced by meals to inhibit the rise of the blood sugar levels of diabetics after meals.
摘要:
The present invention provides a small-sized preparation that is easy to take, containing 26% or more of nateglinide and 28% or more of at least one disintegrant selected from the group consisting of carmellose or salts thereof, sodium carboxymethyl starch, croscarmellose sodium, crospovidone, partly pregelatinized starch and low-substituted hydroxypropyl cellulose, based on the total mass of the preparation. The preparation of the present invention has high contents of nateglinide, which can be absorbed immediately to exhibit a hypoglycemic action.
