Key messages:

  1. Production of compacted mixed pellets from vegetable, biogenic residues and waste is possible
  2. Mixed pellets are suitable for generating synthesis gas for high-temperature process heat
  3. Optimization of the production of compacted mixed pellets of biogenic residues and waste is necessary for a continuous process
  4. To optimize the energetic yield, a suitable combustion regime is necessary, both on the fuel side (gas cleaning) and on the burner side


Target of the project: to develop industrial mixed- pellets for the upstream gasifier of Fraunhofer- UMSICHT as well as for the production of climate- change- gas as a substitution of natural gas for kilns in the company Rösler CeramInno.
So we have to research a cheap recapture for energy- molds- pellets and a totally new, techno ceramical kind of production. The result shall be an absolutely homogenic material for the burning process made from special residues and wasts by an economical production.
The new innovative process promises to reduce extremely the emission of CO2 according to the climate change targets.  


Rösler CeramInno
Rösler CermaInno will classify special residues and wastes concerning process for the ceramic technical production and for the winning of burning gas in the project “KlischGa”.
The grinding of all substitute materials will be made in different grinding machines. From the produced powder we will develop on base of the thermos- chemical characteristics. From these powders we will develop on base of the thermos- chemical characteristics mixed materials, which will bring – so we hope – a high energetic result.
The production of process- gas by new research industry mixed pellets in a fast- firing- furnace chamber and the furnace in the carburettor- stand by Fraunhofer- UMSICHT.

Fraunhofer IKTS
Fraunhofer IKTS will realise within the Klischga project  the material based procedural concept for manufacturing industriell pellets with dedicated structures for gasification. Therefor all steps of the process are to research beginning with site identification and preparation of the starting materials across the develoment of optimal processible mixtures of materials until extrusion and drying to ruged structures are optimal for gasification and realise the transfer to industriell dimension.

Fraunhofer UMSICHT
Within the Klischga project, Fraunhofer UMSICHT will carry out the gasification of the biomass molds produced by IKTS and Rösler CeramInno using an upstream gasifier. Main interest of the investigations is in the determination of the gasification behavior of the biomass molds and the amount of non-converted carbon
