A powder comprises a mixture of up to 40 weight percent activated cokes and inert materials. In the mixture, at least one of the inert material components is matched in terms of its grain size distribution to the grain size distribution of the activated coke component so that in a gas medium at rest, the speed of vertical descent of the coarse grain of the inert material component is substantially equal to the speed of vertical descent of the coarse grain of the activated coke component.

Mixed powder containing a carbon compound

A process is disclosed for disaggregating waste materials which contain at least partially reusable elements, mainly metals, plastics and cardboard. The waste materials are stirred in water by mechanical forces, large pieces, in particular plastic pieces, are coarsely crushed and soluble elements, in particular cardboard, are dissolved. The metallic elements are separated from the suspension as heavy materials, the remaining coarse solids, in particular plastics, are mechanically separated from the suspension, and the suspended fine solids are separated from the suspension by dewatering.

Process for disaggregating waste materials which contain at least partially reusable elements

A powdered medium for the cleaning of exhaust gases, e,g. smoke and gases from industrial chimneys, employing the principle of dry adsorption, which includes a mixture of activated cokes with inert materials which have no dust explosiveness To prepare a mixture containing powdered activated cokes, in which mixture the concentration of carbon is up to 30% by weight and which when used in the airstream process under essentially all operating conditions, is not subject to virtually any fluctuations in concentration such that with a concentration of oxygen up to 21% by volume, no dust-explosive fractions can form, at least one inert material component in the mixture is matched in terms of its grain size distribution to the grain size distribution of the activated coke component, so that in a gas medium at rest, the speed of vertical descent of the coarse grain of the inert material components is substantially equal to or greater than the speed of vertical descent of the coarse grain of the activated coke components. The powdered medium can be used in essentially all exhaust gas cleaning systems, in separately operated or upstream or downstream adsorption stages employing the airstream principle.

Method for the cleaning of exhaust gas and prevention of explosions

A method for recovering halogenated hydrocarbons (FCH) from synthetic foams wherein halogenated hydrocarbons (FCH) are released from synthetic foam in a hermetically sealed processing chamber and transferred to a gaseous carrier medium of steam. The steam/FCH mixture is removed from the processing chamber and subjected to condensation to remove pure FCH from the condensed water.
