    摘要: In a process for the treatment of at least one mixture of solid and liquid waste substances which contains at least one metal such as Fe and/or compounds thereof, for example oxides, the mixture occurring in a condition in which it can be used at least only with difficulty, the mixture is at least extensively homogenized and mixed with at least one very fine-grain dry substance containing fly ash and/or coke. The resulting mixture is of such a nature, for example being at least predominantly in the form of agglomerates, that it can be fed to a thermal procedure, possibly after a grading operation.

    摘要: In the process, the wet sewage sludge originating from a preceding mechanical dewatering is mixed with brown coal, brown coal coke or their mixtures in a weight ratio of sewage sludge to brown coal or its mixtures with brown coal coke of 1:3 to 3:1 and subsequently compacted wet at moderate compaction pressures above 50 bar to dimensionally stable mouldings. The briquetted mouldings can then be fed to a power station boiler as an auxiliary fuel to a thermal utilization or utilized chemically in a pyrolysis or gasification process for the production of fuel gas or synthesis gas.

    摘要: A process is provided for removing noxious pollutants containing sulfur and/or fluorine compounds from gaseous or liquid media by adsorption of the compounds on coke. The coke is produced by conventional processes from lignite (brown coal) containing alkaline ash compounds, particularly CaO and MgO as well as possibly Na.sub.2 O, Al.sub.2 O.sub.3 and K.sub.2 O. The coke with adsorbed sulfur and/or fluorine pollutants is incinerated at temperatures selected from 700.degree. C. and 1050.degree. C. such that the pollutants combine chemically with the alkaline ash compounds so that the pollutants become bound in the coke ash rather than being emitted to the environment in the combustion gases.
