Abstract: This invention is based upon the discovery that activated carbon can be used to sequester polycyclic aromatic hydrocarbons that may be present in asphalt and creosote compositions. The treatment of asphalt and creosote compositions with activated carbon accordingly reduces the level of free polycyclic aromatic hydrocarbons in such compositions by sequestering them therein or removing them from the composition. After being sequestered the polycyclic aromatic hydrocarbons remain trapped in the asphalt or creosote composition, and are not available to the environment during normal processing into useful industrial products. This sequestration reduces the risk of exposing humans and the environment to the polycyclic aromatic hydrocarbons which would otherwise be free to migrate from the asphalt or creosote product during manufacturing and the service life of the product.

Abstract: A process and a device for dry separation of a conglomerate of metal scrap of non-magnetic particles from magnetic ones. Dry separation equipment for metal scrap which have a sequence of magnets placed in line, the poles of which are north-pole to south-pole are unable to meet this requirement. This insufficiency is due to the fact that the conglomerate of metal scrap is not sufficiently shook. This procedure does mean that at the end of transportation there is still non-magnetic material and other stuff fixed to the magnetic material. Intensive motion necessary is achieved by this invention by locating magnets adjacent to one another with equal poles, north-pole to north-pole and south-pole to south-pole and so on.
