Abstract: An objective of the present invention is to provide a production method that enables PHA (e.g. PHA powder) to be produced with high productivity. The above is achieved by providing: a method for producing a polyhydroxyalkanoate, including the steps of (a) preparing an aqueous suspension that contains a polyhydroxyalkanoate and an alkylene oxide-based dispersing agent and has a pH of not more than 7 and (b) spray-drying the aqueous suspension prepared in the step (a); and the like.

Abstract: Provided are: a dispersant which has good dispersibility and reduces electronic resistance; and a battery having excellent characteristics, which uses this dispersant and is decreased in the ionic resistance and the reaction resistance. A dispersant contains a triazine derivative represented by general formula (1), and an amine or an inorganic base (in general formula (1), R1 is as defined in the description).

Abstract: A method for producing chlorinated polyvinyl chloride includes bringing chlorine gas into contact with a mixture comprising a polyvinyl chloride powder and at least one inorganic filler; and irradiating the mixture with UV light to perform a chlorination reaction. At least one inorganic filler is selected from the group consisting of silica, carbon black, and talc.

Abstract: A cell catalyst composition according to the present invention includes a carbon catalyst granule and a binder resin, and at least a part of the binder resin includes a resin (B) including a hydrophilic functional group. The carbon catalyst granule is (i) a carbon catalyst granule wherein carbon catalyst (A) particles are bound to each other by using at least the resin (B), or/and (ii) a carbon catalyst granule wherein carbon catalyst (A) particles form a sintered body and are thereby bound to each other. The carbon catalyst (A) includes a carbon element, a nitrogen element, and a base metal element as constituent elements. Further, an average particle diameter of the carbon catalyst granule is 0.5 to 100 ?m, and a sphericity of the carbon catalyst granule is equal to or greater than 0.5.

Abstract: A sludge receiving facility is provided with upper and lower structures respectively having inner spaces communicating with each other, wherein sludge tanks each having a sludge charging port are provided in the lower structure, and a partition wall configured to partition a carrying-in space of the upper structure from the inner space is provided, the sludge receiving facility including: outside air blowing means; air circulating means configured to enable the inner space and the carrying-in space to communicate with each other; first exhausting means configured to exhaust air from an upper part of the carrying-in space; second exhausting means configured to exhaust air above the sludge charging port; and third exhausting means configured to exhaust air inside the sludge tanks, wherein opening/closing means are respectively provided in the circulating means and the first to third exhausting means.
