A process for energy- and emission-optimized iron production and an installation for carrying out the process. A first partial amount of a generator gas produced in a melter gasifier is used as a first reducing gas in a first reduction zone. A second partial amount is fed to at least one further reduction zone as a second reducing gas. In addition, after COscrubbing, a partial amount of top gas removed from the first reduction zone is admixed with the generator gas after the latter leaves the melter gasifier, for cooling the generator gas.

[object Object]

The invention relates to a process for treating a hydrocarbonaceous waste material, in particular a rolling scale slurry and/or grinding slurry, the waste material being heated in a dryer, preferably moving, by the indirect supply of heat, and in the process hydrocarbons, if appropriate together with other volatile components, in particular HO, being removed. In this process, in the dryer, at low temperature, the hydrocarbons are broken down in a specific way, the hydrocarbons being broken down by chemical and/or radiation means, which effect decomposition of the hydrocarbons of low volatility into highly volatile hydrocarbons, preferably decomposing high molecular weight hydrocarbons into lower molecular weight hydrocarbons, and the hydrocarbons, if appropriate together with the other volatile components in particular together with the HO, are at least partially discharged, in particular by suction, from the vessel. The invention also relates to a apparatus for treating a hydrocarbonaceous waste material.
