Activated carbon from wine marc

Technical data:

  • Continuously operated pyrolysis and activation reactor for the production of biochar and activated carbon from biomass.
  • Horizontal screw reactor with adjustable temperature range up to max. 900 °C.
  • Residence time in the reactor freely adjustable (min. 10 minutes)
  • Nitrogen purging for low-oxygen conditions in the pyrolysis reactor
  • Connection for adding reaction gases (CO2, O2) or steam to the reactor to produce activated carbons by partial oxidation.
  • Maximum input: 2 kg dry mass per hour

Application:

Investigations into the suitability of residual biomass for the production of high-quality plant and activated carbons for various applications in the environmental and agricultural sectors.

A particular focus is on the production of activated carbons for the removal of organic trace substances from municipal wastewater and for the substitution of conventional activated carbons based on fossil raw materials.

IFBB test facility

Technical data:

The IFBB (integrated production of solid fuel and biogas from biomass) test plant consists of a mixing plant for mixing warm water with biomass and a screw press (VetterTec, type AV) for the mechanical separation of solid and liquid phase.

Application:

The plant is used in Neu-Eichenberg to separate biomass into liquid and solid phases. The relatively dry, fiber-rich press cake has a reduced mineral content and can therefore be used as a solid fuel or for the production of vegetable and activated carbons after subsequent compaction. The press juice with its increased sugar and mineral content can be used as fertilizer or as a substrate for biogas production.

Pellet mills

Technical data:

Pellet mill Amandus Kahl 14-175 with different dies for different biomasses and pellets with a diameter of 4, 6 or 8 mm

Pellet mill qteck PP230UG, production capacity 150-250 kg/h, pellets with a diameter of 6 mm or 10 mm.

Application:

The pellet press is used for compacting biomass. The press can be used to pelletize wood, straw, hay, grass, IFBB press cake and other materials.
