摘要： PROBLEM TO BE SOLVED: To obtain powdery activated carbon capable of achieving high packing density even when the activated carbon is molded with a small quantity of binder by specifying a median particle size and a ratio of particles having a particle size which is a specified ratio of the median particle size or below. SOLUTION: This activated carbon has a >=10 μm and =300 m2/g specific surface area and shows high adsorptivity. Carbides of coconut shell, wood, phenolic resin or the like and coal are used as raw materials of the activated carbon. An electrode of activated carbon having >=0.65 g/cc density at the time of molding can be manufactured. In order to mold the activated carbon powder into a sheet, 100 pts.wt. activated carbon powder is mixed with 5-10 pts.wt. binder such as polyvinylidene fluoride and then compression molding is carried out utilizing a roll press or the like. This powdery activated carbon may be manufacture by repeating compression and mixing of the powdery activated carbon in high speed, though the method for manufacturing the same is not limited in particular.

摘要： PROBLEM TO BE SOLVED: To obtain an air cleaning agent capable of efficiently removing lower aldehydes and excellent in heat resistance and safety by adding a urea compd. having a urea bond in its molecule to a porous carrier. SOLUTION: A urea compd. having a urea bond in its molecule is added to a porous carrier to obtain this air cleaning agent. The urea compd. is prepd. by substituting one or more hydrogen atoms of urea alkyl or acyl groups and may have any of linear and cyclic structures. The porous carrier is not particularly limited if it can carry the urea compd., aniline and transition metals. The urea compd. is carried on the porous carrier by dissolving the compd. in water, after dipping the carrier in the resultant aq. soln., drying it in the case of using water-soluble urea. The aq. soln. may be sprayed on the carrier and dried to carry the compd.

摘要： PROBLEM TO BE SOLVED: To provide a device for treating wastewater and a method therefor which can be applied to a treatment of high concentration COD wastewater and has a long life and a compact construction. SOLUTION: In the wastewater treatment device which has a wastewater introducing port and a treated water outlet port 7 and comprises a packed bed filled with activated carbon particles on which miroorganisms are fixed, an aeration means is provided in an activated carbon layer 2. If a wastewater 1 is treated using such aeration means, since there is no deficiency of dissolve oxygen in the layer 2, the whole layer 2 can be effectively used and even a wastewater of high COD concentration can be treated. Since organic matters adsorbed on the activated carbon are decomposed by the microorganisms, the microorganisms of the activated carbon can be regenerated so that the adsorption performance can be maintained for a long period of time, resulting in a prolonged operation.

摘要： PROBLEM TO BE SOLVED: To provide a fluidized bonding method that makes absorbent particles bondable not only to the external surface of an air-permeable sheet but also to the surface of the internal tissue thereof at the same density without causing the decrease is adsorptivity of the particles, and to provide an apparatus therefor. SOLUTION: After an adhesive is adhered to the external surface and to the surface of the internal tissue of a sheet and then films formed in gaps of the tissue are removed by air blow, the sheet is passed through a fluidized bed 9 of absorbent particles and is pressed at a pressure roll 3. The sheet is then passed through a vibrator 4, where adsorbent particles insufficiently bonded fall off by vibration, and led to drying rolls 5 to dry the adhesive and to further cause adsorbent particles insufficiently bonded to fall off. Those particles separated from the sheet fall down to the fluidized bed and are reused. An adsorbent- contg. sheet obtd. by this method and apparatus is excellent in capability for removing traces of bad odor components in the air and is used for filters, etc., of air cleaners and air conditioners.

摘要： PROBLEM TO BE SOLVED: To almost perfectly remove a very small of inorg. mercury and org. mercury contained in a hydrocarbon by bringing an absorbent into contact with the hydrocarbon being an intermediate of a pertroleum product or petrochemical product such as naphtha in a liquid phase. SOLUTION: An adsorbent absorbing mercury and a mercury conpd. contained in a liquid hydrocarbon is obtained by supporting an acid in activated carbon. Herein, as the activated carbon, one characterized by that vol. of micropores with a pore radius of 8Å or less is 80ml/g or more is pref. and, as the acid supported on activated carbon, hydrochloric acid, sulfuric acid and phosphoric acid are pref. and hydrochloric acid is more pref. Activated carbon used as a carrier is pref. obtained by activating a carbonaceous raw material in an atmosphere with steam content of 30vol.% or less. Further, a mercury removing method bringing activated carbon having an inorg. acid supported thereon into contact with hydrocarbon being an intermediate of a petroleum product of petrochemical product such as naphtha in a liquid phase is also included.

摘要： PROBLEM TO BE SOLVED: To regenerate the deodorizing function of a deodorant for the semipermanent use thereof by causing a porous adsorbent as a titanium oxide IV carrier to contain a component selected from a group of an ultraviolet sensitizer, a light transmitting ceramic and a light transmitting plastics. SOLUTION: An adsorbent made of a porous material with titanium oxide IV carried thereon is caused to contain a photocatalyst with at least one type of components selected from a group of three components of an ultraviolet sensitizer, a light transmitting ceramic and a light transmitting plastics contained therein. Also, the titanium oxide IV with either an anatase or a rutile type crystal may be used. In this case, however, an anatase type crystal having a higher photooxidation function is preferable. Furthermore, any substance with a large specific surface area as well as a large physical adsorptivity due to van der Waals force may be widely used as the adsorbent composed of a porous material. For example, activated carbon or the like can be mentioned.
