Development of a novel composite process for the high-temperature pyrolysis of carbon-containing residual and waste materials for the purpose of converting them into a fuel gas suitable for CHP plants.
Cooperation project under the leadership of the company Wahrheit Anlagenbau GmbH (Rhauderfehn), Managing Director: Dipl.-Ing. Ludger Wahrheit, Duration: 01.10.2021 - 30.09.2024, Funding: BMWK as part of the ZIM program.
In the northwest German home of WAHRHEIT's headquarters, there is a high demand for possible uses of biological municipal waste such as turkey manure, dry chicken manure, fermentation residues and sewage sludge. Based on the company's special knowledge, the idea was born to develop a process that works at high temperatures with maximum use of its own energy and whose products can be recycled. The innovative idea is to integrate the pyrolysis process into an RTO (Regenerative Thermal Oxidation). The material used for the reactor is a high-temperature resistant ceramic such as silicon carbide. High working temperatures above 1,000 °C and steam as a reaction partner enable thermo-chemical processes that are not established in state-of-the-art pyrolysis plants. This means that there is a chance of very pure products on the coke and gas path. Excess heat can be converted into electricity and heat in a combined heat and power plant.
The plant technology should be economical for the operators in small operating sizes.
The CUTEC research center with the TP department serves as a development partner for WAHRHEIT. In Clausthal, extensive equipment for experiments above 900 °C is available. The results will be used in a chemical-physical model to be created, which is based on the ChemCAD program package. The aim is to use the model in such a way that future customers of Wahrheit will be able to predict the mass, material and energy flows of untested biomasses.
