Ablative Fast Pyrolysis Plant
Our Ablative Fast Pyrolysis Plant is designed for the thermochemical processing and utilization of biomass and other organic polymeric wastes to produce liquid and organic products as well as fine char.
The term “ablation” refers to the phenomenon that occurs when a solid, exposed to a high external heat flux, produces new solids, liquids or gases that can be removed quickly and continuously.

In 2020 our first and unique Ablative Fast Pyrolysis System (AFP) left our hometown Lüneburg on its way to California (USA). The entire portable system has a throughput of 500 kg of biomass per hour and produces 200.0000 Liter of bio-oil in the course of the project.
The concept of the AFP differs significantly in concept from other methods of fast pyrolysis:
- In ablative pyrolysis, heat is conducted from a hot reactor wall in order to melt biomass that is pressed against the wall. The pyrolysis front moves unidirectional through the biomass body. The remaining oil film provides lubrication and evaporates quickly to volatile components (bio-oil)
- The reaction rate is strongly influenced by the pressure, the relative velocity of the biomass with the heat exchange surface and the reactor temperature
How does the AFP function?
- The dry input material is fed to the drying module of the plant and dried to 10% moisture content
- The dried mass enters the pyrolysis reactor via a lock hopper
- Here, the heat generated in the energy module is used to thermally crack the dry feedstock, excluding oxygen
- A vapor-gas mixture and fine coke is produced
- In the cleaning module, the mixture is separated from the charring dust and fed into the condensation module, where the rapid cooling and condensation of the mixture leads to the separation of liquid and combustible gas
- A partial flow of the gas is fed to the combustion in the energy module
- The fine coal is fed into a discharge module via a screw feeder. The discharge module handles the accumulation and distribution of the batches. The batch can either be used as fertilizer or for combustion in the energy module

Due to the modular structure of the plant, the production complex can be installed on different sites and solid foundations:
Furthermore the modular design enables a quick and easy installation without unexpected costs. By installing additional modules, the system can easily be expanded to the required quantities. The transport of the production complex can be carried out by trucks, trains and the moduls fit into standard ship containers.
The plant can use the following materials as starting material:
- Sewage sludge
- Lignocellulose biomass waste in the form of wood sawdust, shavings, etc
- Peat and other organic polymer wastes
- Waste contaminated with oil products
