Disclosed is a process for the emission-free generation of energy and/or hydrocarbons and other products by utilizing carbon-containing materials, in a first process stage (P1) carbon-containing materials are supplied and pyrolyzed, thereby producing pyrolysis coke (M21) and pyrolysis gas (M22). In a second process stage (P2), the pyrolysis coke (M21) from the first process stage (P1) is gasified, thereby producing synthesis gas (M24), and slag and other residual materials (M91, M92, M93, M94) are removed. In a third process stage (P3), the synthesis gas (M24) from the second process stage (P2) is converted into hydrocarbons and/or other solid, liquid and/or gaseous products (M60), which are discharged. The three process stages (P1, P2, P3) form a closed cycle. Excess gas (M25) from the third process stage (P3) is conducted as recycled gas into the first process stage (P1) and/or the second process stage (P2), and the pyrolysis gas (M22) from the first process stage (P1) is conducted into the second process stage (P2) and/or the third process stage (P3); wherein hydrogen is supplied in the third process stage and carbon dioxide is supplied in the first process stage or second process stage. Preferably, the heat energy for the pyrolysis reactions in the first process stage is provided in part or completely by returning a 20 part of the hot synthesis gas from the second process stage into the first process stage, and/or by partial oxidation of the carbonaceous starting material and the resultant pyrolysis coke. |
