Thermal and chemical utilization of carbonaceous materials, in particular for emission-free generation of energy
First Claim
1. A facility for emission-free generation of energy and/or hydrocarbons and/or other products by utilizing carbonaceous materials, with a utilization installation comprising a utilization unit with a first subunit for carrying out a pyrolysis of the carbonaceous materials to form pyrolysis coke and pyrolysis gas,wherein the pyrolysis coke is lying on a conveying means adapted for continuous horizontal transport of lumpy pyrolysis coke along a horizontal direction;
- a second subunit for carrying out a gasification of the pyrolysis coke in a fire bed, at a temperature above 850°
C., to form synthesis gas and residues;
wherein the fire bed is formed by pyrolysis coke lying on a conveying means adapted for continuous horizontal transport of lumpy pyrolysis coke along a horizontal direction; and
a third subunit for carrying out a conversion of the synthesis gas into hydrocarbons and/or other solid, liquid and/or gaseous products, and a recycle gas comprising carbon dioxide, water vapor, and unreacted carbon monoxide and hydrogen, the third subunit of the utilization unit comprising a Fischer-Tropsch synthesis stage, and/or a liquid-phase methanol synthesis stage;
wherein all three subunits of the utilization unit are pressure-tightly closed and form an essentially closed cycle;
a transport pipe for the pyrolysis gas connects the first subunit pressure-tightly to the second subunit, such that the point of entry of the pyrolysis gas into the second subunit is above the fire bed of the pyrolysis coke;
means are provided that allow blowing oxygen into the fire bed, spatially separated from the point of entry of the pyrolysis gas, such that the pyrolysis gases do not come into contact with oxygen; and
a transport pipe for the synthesis gas connects the second subunit pressure-tightly to the third subunit; and
a transport pipe for the recycle gas connects the third subunit pressure-tightly to the first subunit.

Abstract
A process for the generation of energy and/or hydrocarbons and other products utilizing carbonaceous materials. In a first process stage (P1) the carbonaceous materials are supplied and are pyrolysed, wherein pyrolysis coke (M21) and pyrolysis gas (M22) are formed. In a second process stage (P2), the pyrolysis coke (M21) from the first process stage (P1) is gasified, wherein synthesis gas (M24) is formed, and slag and other residues (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. Surplus gas (M25) from the third process stage (P3) is passed as recycle gas into the first process stage (P1), and/or the second process stage (P2), and pyrolysis gas (M22) from the first process stage (P1) is passed into the second process stage (P2), and/or the third process stage (P3).
