Thermal and chemical utilization of carbonaceous materials, in particular for emission-free generation of energy
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).

METHOD OF OPERATING A FIXED-BED GASIFIER FOR PRODUCING A PRODUCT GAS FROM POURABLE CARBONACEOUS PARTICLES
A method of operating a fixed-bed gasifier includes positioning a tapping element at a first point above a bed of fuel particles, lowering the tapping element into the fuel particles along a first linear path to form a first linear passage in the fuel particles, raising the tapping element to retract the tapping element from the fuel particles along the first linear path so that the tapping element exits the fuel particles from the first linear passage, positioning the tapping element at a second point above the fuel particles, lowering the tapping element into the fuel particles along a second linear path to form a second linear passage in the fuel particles, and raising the tapping element to retract the tapping element from the fuel particles along the second linear path so that the tapping element exits the fuel particles from the second linear passage.
