Abstract: A plant for processing solid fossil fuels in which the fuel is crushed and is conveyed by flue gas to further processing stations. In the further stations, the fuel is desulfurized and hydrolyzed and is separated into solid and gaseous components for use in the generation of steam or for supply to a fuel gas supply network.

Abstract: Disclosed is a process for gasifying carboanceous material with the use of two fluidized beds superimposed on a fixed bed, and a flue dust gasification chamber arranged inside the reactor between the fluidized beds.

Abstract: A method of reducing the sulfur content of coal, reduced to dust, by means of its own or external thermal energy and by means of rapid coking and/or rapid partial destructive distillation of the coal. The coal dust, which has been ground to less than 0.1 mm and, if necessary, preoxidized in 1 to 4 seconds at 350.degree. to 450.degree. C., is brought to a reaction temperature of 700.degree. to 1100.degree. C. This reaction temperature may be reached directly, either by means of carrier or heating gas heated to over 1000.degree. C., or by means of the partial combustion of the coal with air or oxygen, at heating rates greater than 20,000.degree. C./min. This reaction temperature may also be reached indirectly, at heating rates of less than 20,000.degree. C./min, by means of gaseous, liquid, or turbulent heating carriers. The coal dust is allowed to stand for 1 to 6 seconds at a pressure of 1 to 15 bar until the coke dust and gas which are produced separate from one another.

Abstract: A method of generating gas and coke dust by means of rapid degasification and rapid vaporization, with simultaneous extensive desulfurization, of coal ground into dust. In a first step, one portion of coal is subjected to complete or partial vaporization. In a second step, which immediately follows the first step, another portion of coal is subjected to degasification in the same or in associated reaction chambers. In the degasification, the solid and gaseous products obtained during the vaporization which are at a higher temperature level than that of the degasification step, transfer heat directly to the coal introduced into the degasification step, thus for covering the heat required for the degasification.

Abstract: A radiation-hardenable binder consisting of a reaction product of:(A) 1 gramme equivalent of NCO of a polyisocyanate containing 2 to 3 isocyanate groups per molecule,(B) 0 to 0.7 gramme equivalents of OH of a polyol containing at least 2 OH-groups per molecule, free from organically combined sulphur,(C) 0.01 to 0.7 gramme equivalents of OH of a hydroxyalkyl acrylate containing 2 to 6 carbon atoms in the alkyl group characterized in that the reaction product additionally has incorporated therein:(D) 0.01 to 0.3 gramme equivalents of OH of a polyol containing thio or dithio groups or thio and dithio groups, with at least 2 OH-groups per molecule,the sum of the OH gramme equivalents B to D is from 1 to 1.2, and the content of organically combined sulphur, derived from the thio and dithio groups, is from 0.01 to 10% by weight, based on the binder.

Abstract: Radiation-crosslinkable diluents for radiation-hardenable compositions (binders) consisting of a mixture of triacrylates of a reaction product of trimethylol propane and ethylene oxide with an average degree of ethoxylation of from 2.5 to 4, the ethoxylated trimethylol propane being substantially free from trimethylol propane and having the following distribution:4 to 5% by weight of monoethoxylation product14 to 16% by weight of diethoxylation product20 to 30% by weight of triethoxylation product20 to 30% by weight of tetraethoxylation product16 to 18% by weight of pentaethoxylation product.6 to 8% by weight of hexaethoxylation product.The diluents effectively reduce the viscosity of radiation-hardenable compositions and do not have any adverse effect upon their reactivity or upon the properties of the resulting hardened products.
