    Abstract: In the fighting of fires or protection of objects from fire by applying thereto water, the improvement which comprises dispersing in the water particles of a cross-linked water-insoluble but hightly water-swellable acrylic acid derivative polymer in an amount insufficient to bring the viscosity above 100 mPa's. Advantageously, the particles are present in an amount such that after swelling the swollen particles hold 60 to 70% by weight of the total water, the particles are from 0.1 to 3 mm in diameter and are present in from 0.1 to 0.6% by weight of the water, the polymer being a copolymer of an acrylic acid, the water containing silicic acid and/or a silicate as well as sodium, potassium or ammonium ions. The water is freely pumpable but the swollen particles adhere to surfaces they contact rather than running off rapidly.

    Abstract: The activated charcoal filter layer for gas masks contains a highly air-permeable, three-dimensional carrier framework essentially stable in shape, formed of wires, monofilaments or stays, to which a layer of granular, particularly spherical activated charcoal particles with a diameter of 0.1 to 1 mm is affixed. The carrier framework can be composed of wires, monofilaments or stays, the distance between them being at least twice as great as the diameter of the activated charcoal particles. The carrier framework can also be a large-pore reticulated polyurethane foam which has a weight of 20 to 60 g/l and pores with a diameter of 1.5 to 3 mm. The carrier framework can furthermore consist of wire netting or wire mesh arranged in layers, as well as of plastic or wire spirals with a length equal to and up to 10 times their diameter, or of wires or monofilaments with a length of 2 to 10 mm, which are held by twisted metal or plastic wires and project perpendicular from this axis in the shape of a spiral staircase. In spite of a very slight pressure drop, the filter performance is excellent.

    Abstract: The invention refers to a process for producing activated carbon having catalytic activity by carbonization and subsequent activation of carbonaceous organic polymers, wherein carbonaceous organic polymers into which, in the course of their formation, at least one metal atom and/or metal ion has been interpolymerized are subjected to a carbonization and subsequent activation, forming an activated carbon loaded with the metal atom and/or metal ion. This obviates subsequent loading with the metal by costly and inconvenient impregnation after the activated carbon has been produced. By endowing the starting materials with the metal, moreover, a more homogeneous loading is achieved, and that homogeneous throughout all kinds of pores (i.e. macropores, mesopores and micropores), so that catalytic activity is enhanced, and in addition, activation is accelerated.

    Abstract: A method of processing spent ion-exchange resins contaminated with suspended particles, inorganic residues and/or organic foreign matter so as to render the resin ineffective for continued use, by which method this waste material can be processed to produce useful activated carbon particles instead of simply being dumped in a landfill. In accordance with the invention, granular spent organic ion-exchange resin having an ash content of from 5 to 30% is first dried, then carbonized under a substantially inert atmosphere at a temperature of 300 to 900° C., the inert atmosphere containing 0.2 to 4 volume percent oxygen up to 400° C., and finally activated at a temperature of at least 700° C. under a substantially inert atmosphere containing 3 to 50 volume percent steam.
