WAHRHEIT High temperature pyrolysis

Development of a new composite process for the high-temperature pyrolysis of carbon-containing residual and waste materials for the purpose of conversion into a fuel gas suitable for CHP.

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 source: BMWK within the framework of the ZIM program.

In the northwest German home of the headquarters of WAHRHEIT, 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 special knowledge of the company, the idea of developing a process that works at high temperature with maximum use of its own energy and whose products allow material recycling was born. The innovative idea is the integration of the pyrolysis process into a 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 as well as steam as reaction partner enable thermo-chemical processes which are not established in pyrolysis plants according to the state of the art. This offers the chance of very pure products on the coke and gas path. Surplus 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 the development partner for WAHRHEIT. In Clausthal, extensive equipment is available for experiments, even above 900 °C. The results will be presented in a report to be prepared. The results will be used in a chemical-physical model to be created, which is based on the program package ChemCAD. The aim is to use it in such a way that future customers of Wahrheit will be able to predict the mass, material and energy flows even for biomasses that have not been tested.
