As its name suggests, the laboratory of reduction processes focuses on waste material treatment with the use of thermal processes in a reducing environment. The laboratory has two sections.
The first section is focused on waste biomass processing, in the order to come up with products with a higher added value, i.e. using the torrefication process to produce "super pellets", using pyrolysis to produce "bio coal" or the production of carbon activated sorbents by carbonization. Biomass is processed both in a batch laboratory scale and on a continuous pilot plant. Naturally, these solid products are also analysed, including the resulting gases and fluids.
The second section focuses on waste polymer material processing done with the use of catalytic pyrolysis. This is also called chemical recycling and its principle is to recover monomers (or similar chemical substances) from polymers, and then re-use this chemical substance to produce this polymer again. The part of the polymeric materials which is impossible to process by chemical recycling as well as other types of waste, e.g. products of organic processing, is reformed to hydrogen, using commercially available catalysts as well as our own ones.

Research activities

  • The waste management and recycling of solid and liquid wastes, or production of species with higher potential – hydrogen etc.
  • Sorbents producing from waste carbonaceous materials for adsorption of pollutants in air and water.
  • Thermal treatment of waste material with catalyst (catalytic pyrolysis).

Basic equipment

Equipment for thermal treatment of solid and liquid wastes:

  • Vertical or horizontal batch pyrolysis reactor (max. volume 30 dm3, max temperature 800-850°C, a gas inlet for the gasification).
  • Batch pyrolysis reactor (max. temperature 1000°C) and microwave reactor (power up to 1 kW) for the material balance of thermal treatment (max. feed 100g).
  • Catalytic reactor with controlled heating for decomposition of hazard and organic compounds (cracking of tars), treatment of pyrolysis products (dry reforming, etc.).
  • Plasma processes module, the electrical power supply with plasma reactor generating “Gliding Arc”.

Offered services

  • Material and energy balances for thermal treatment of biomass, wastes, hazard wastes and other materials.
  • Analysis of gaseous and liquids product from waste treatment.
  • Analysis of water content by KF titration.
