Abstract

Disclosed is a method for producing water-absorbent resin particles, the method comprising: forming a hydrogel polymer by polymerizing a water-soluble ethylenically unsaturated monomer through reverse-phase suspension polymerization in a reaction solution containing a surfactant having an HLB of 7-16; forming aggregated particles; extracting some water to form a concentrate; and surface cross-linking the aggregated particles in a mixture containing the concentrate and a surface crosslinking agent. The amount of an internal cross-linking agent is 0.093 mmol or less per mole of the water-soluble ethylenically unsaturated monomer. The polymer particles formed from the hydrogel polymer before forming the aggregated particles have a median particle size of 150 μm or more. The mixture is formed by mixing a surface crosslinking agent with a concentrate containing water at a moisture content of 15-50 mass% on the basis of the mass of the polymer.

Abstract

A recovery method according to one embodiment of the present invention comprises: a first concentration step in which a starting material gas is introduced into a first pressure swing adsorption device and a first gas in which carbon dioxide has been concentrated is recovered; and a second concentration step in which the first gas is introduced into a first pressure swing adsorption device and a second gas in which carbon dioxide has been concentrated is recovered. The first pressure swing adsorption device has a first adsorption tower in which activated carbon is housed, and the second pressure swing adsorption device has a second adsorption tower in which zeolite is housed. In the first concentration step, carbon dioxide contained in the starting material gas introduced into the first adsorption tower is adsorbed onto the activated carbon and subsequently desorbed so as to recover the first gas, and in the second concentration step, carbon dioxide contained in the first gas introduced into the second adsorption tower is adsorbed onto the zeolite and subsequently desorbed so as to recover the second gas.

Abstract

Provided is a water-absorbent resin capable of inhibiting backflow and leakage of a liquid absorbed by an absorbent body. When measured by a measurement method, this water-absorbent resin shows a repeated water absorption amount in an inclined state of 35 g or more. In the measurement method, 1.0 g of the water-absorbent resin is uniformly spread in a circular plastic petri dish having an inner diameter of 8.5 cm and a height of 1.7 cm. Subsequently, 30 g of physiological saline is supplied at once on the water-absorbent resin. Immediately thereafter, the petri dish is shaken 10 times from side to side and then allowed to stand for 3 minutes to form a swollen gel layer in which the physiological saline is absorbed by the water-absorbent resin. Separately, a device is prepared by fixing an acrylic plate having a flat main surface in such a manner that the main surface is at an angle of 30° to the horizontal plane. On the upper surface of the swollen gel layer, an air-through non-woven fabric, which has a weight per unit area of 21 g/m2 and cut into the same size as the inside of the petri dish, is placed. Then, the petri dish is stuck to the acrylic plate with tape to avoid slipping off. From a vertical height of approximately 1 cm at the center of the swollen gel layer in the petri dish, 5 g of the physiological saline is poured for 5 seconds using a macropipette. The pouring procedure is repeated 8 times at 1 minute intervals from the start of the physiological saline pouring. The amount of the liquid leaked from the petri dish is measured and subtracted from the amount (i.e., 40 g) of the poured physiological saline. The thus calculated mass of the physiological saline that is retained by the swollen gel layer is regarded as the repeated water absorption amount of the water-absorbent resin.

Abstract

The present invention provides a method for producing water absorbent resin particles which have good general water absorption performances (such as saline absorption) required for water absorbent resins, while additionally having high gel stability and being suppressed in yellowing under high temperature and high humidity conditions. This method for producing water absorbent resin particles sequentially comprises in the following order: a step 1 in which a water-soluble ethylenically unsaturated monomer is polymerized, thereby obtaining hydrous gel particles; a step 2 in which a chelating agent, a sulfite compound and an organic antioxidant are added to the hydrous gel particles; and a step 3 in which the resulting hydrous gel particles are subjected to a surface crosslinking treatment. In the step 2, the moisture content of the hydrous gel particles when the sulfite compound is added thereto is 20% by mass to 75% by mass.
