Abstract: The present invention relates to a process for the oxidative degradation of toxic organic compounds. It comprises mechanical and chemical activation of solids containing toxic organic compounds and subjecting said activated solids to heat spontaneously generated in the presence of oxygen to oxidatively degrade said toxic organic compounds.

Abstract: The present invention relates to a process for the reductive dehalogenation of halogenated hydrocarbons. It comprises reacting halogenated hydrocarbons with a reducing metal and a hydrogen donating compound in the presence of an amine. Preferably, the halogenated hydrocarbons are reacted with lithium, potassium, calcium, sodium, magnesium, aluminum, zinc or iron. Depending on the metal, the complete reductive dehalogenation takes place at temperatures ranging from room temperature to 400° C.

Abstract: 1. Process for the reductive dehalogenation of liquid or solid halogenated hydrocarbons. 2.1 Toxic liquid or solid halogenated hydrocarbons such as DDT, HCH, in particular halogenated aromatics such as TCB, PCB, PCP and PCDD/PCDF as such or as contaminants in waste oil or contaminated soil or soil like materials can, in most cases, not at all be dehalogenated or, at best, on a very lavish scale. According to the present invention said halogenated hydrocarbons can be dehalogenated without any problems. 2.2 This can be achieved according to the present invention through transforming the halogenated hydrocarbons as such and the contaminated material respectively into a finely dispersed solid formulation and heating said formulation for a short time with finely dispersed reducing metals. 2.

Abstract: A method of immobilizing a contaminant comprising mixing the contaminant with a reaction partner that is capable of chemically interacting with the contaminant to form a water-insoluble reaction product, the reaction partner being mixed in the form of a hydrophobic solid preparation, which is either obtained by grinding the reaction partner with an inert material and treating it with a hydrophobing agent or which contains the educt or reaction product of a dispersion by chemical reaction preliminarily treated with a hydrophobing agent, the mixing being conducted to form a soil or soil-like material with cohesive constituents of a clay-like structure.

Abstract: A method of dehalogenating a halogenated hydrocarbon in the presence of a nucleophilic reaction partner, comprising dispersing the halogenated hydrocarbon by chemical reaction (DCR), and dehalogenating the resulting finely dispersed reaction product by means of a strictly chemical conversion with the nucleophilic reaction partner at a temperature between ambient temperature and approximately 510.degree. C.

Abstract: A method of producing a solid secondary raw material that contains calcium sulfate, comprising mixing a waste hydrocarbon with at least one of a waste sulfuric acid and acid waste sulfuric-acid derivative, and combining the mixture with enough powered limestone or fly ash containing calcium carbonate to ensure that the reaction product will solidify by itself, and with at least enough water to ensure the hydration of the formed calcium sulfate. The product is useful in making Portland cement clinker, or in furnace as a fuel and/or a desulfurization additive.

Abstract: A method for forming a uniform distribution of a substance in calcium hydroxide to obtain pulverulent preparations. The substances are those particularly in a fluid stage such as a solvent, emulsion or suspension.

Abstract: A process for forming uniform distributions of at least one substance in a solid. The process comprises forming a predistribution of the at least one substance in at least one compound, e.g., mixing the at least one substance so that it is distributed throughout the at least one compound, and reacting the at least one compound with water to form a hydroxide, which hydroxide has a larger surface area than the at least one compound. Predistribution must take place before a substantial portion of the compound reacts to form the hydroxide. This process can be used to form a dry powder having at least one substance uniformly distributed therein.

Abstract: A method for rendering harmless an oily waste material comprising mixing an alkaline earth metal oxide with a surface active agent which delays reaction between the alkaline earth metal oxide and water, combining the mixture with said oily material, and reacting the alkaline earth metal oxide charged with the waste material with approximately the stoichiometric amount of water to convert the alkaline earth metal oxide to the hydroxide. The alkaline earth metal oxide is preferably calcium oxide and advantageously it is also mixed with a hydrophobizing agent prior to mixture with the oily waste material. The proportions are desirably such that the end product is a solid which can be used as a lining in road construction and at dump sites.
