TChaR® for water purification

TCR® process produces biochar for a wide range of applications

TChaR® is a biochar produced by the Thermo-Catalytic Reforming (TCR®). The main advantages of the TChaR® are the exact process conditions, avoid of contaminant emissions, as well as an excellent and constant quality of the products. Typical input materials for the TCR® are flotsam, sieve residues, digestate from anaerobic digestion plants, brewery spent grain, sewage sludge, between other biomass residues.

 

TChaR® shows several industrial and agronomic applications as:

  • Soil amendment and nutrient carrier in the agriculture as well as garden and landscape applications
  • Filter for water, air and gas purification
  • Barbecue char for substitution of imported char from tropical forests
  • Catalyst support for chemical and biochemical conversion processes

 

Process principle

Enhanced biochar materials can be produced by thermal and/or chemical activation. These enhanced biochars show similar and for some applications even better properties as common activated carbons. The production cost as well as the environmental impact of the enhanced biochars are generally lower than commercial activated carbons.

A fixed-bed filter with enhanced biochars can selective remove unwanted substances from liquid streams i.e. ammonium, organic trace elements (antibiotics, pesticides, etc.) or heavy metals.  

 

 

Sample projects

InterPyro

Project content is the evaluation of pyrolysis coals as well as the production of TCR coke for application tests.

 

Phy2Climate

A global approach to reclaiming agricultural land through a combination of phytoremediation, biofuel production and climate-friendly copper smelting.

 

FERTIMANURE

Fraunhofer UMSICHT is responsible for implementing the German pilot project for nutrient recovery from cattle manure. The innovative process chain will maximise nitrogen recovery and phosphorus utilisation from cattle manure and convert it into the commodity fertiliser ammonium phosphate. In addition, phosphorus-rich biochar will be produced.
