Activated Carbons By Ac&c (Activated Carbons And Chemicals)

We are offering a wide assortment of Activated carbons. A process is disclosed for deactivating or removing aromatic compounds from a kerosene or gas oil, which aromatics are coke precursors in a steam cracking process (conducted in the absence of a catalyst) to convert the hydrocarbons contained in the kerosene or gas oil to hydrocarbons of smaller molecules. The excising occurs by contacting the kerosene or gas oil, before admission to the steam cracking zone, with particulate size activated carbon of 4 mesh to 50 mesh size and physically removing the activated carbon (with at least a portion of the aromatic content of the coke derived from the kerosene or gas oil absorbed thereon) from the slurry before passage of the kerosene or gas oil to the steam cracking furnace. The separation of the activated carbon from the kerosene or gas oil is made in a physical separation zone whereby a wall having aperatures therein, similar to a filter or screen, is sized to permit passage of the kerosene or gas oil through the aperatures with a decreased amount of aromatics and yet prohibit the passage of the fine, particulate activated carbon having polynuclear aromatics absorbed through the aperatures thereon.
