TOLUENE DIISOCYANATE (TDI) HASTELLOY ALLOYE POLYESTER POLYOL POLYETHER POLYOL (PPG) ACTIVE CARBON TiO2 VALVES

Activated carbon, the common factor in hundreds of different applications. Just a grab from the numerous applications: decolourisation of sugar and sweeteners, drinking water treatment, gold recovery, production of pharmaceuticals and fine chemicals, catalytic processes, off gas treatment of waste incinerators, automotive vapour filters, colour/odour correction in wines and fruit juices, additive in liquorice, etc. etc.

 In its numerous applications, activated carbon represents a number of different functionalities:
　
  • Adsorption: the most well-known mechanism, through physical adsorption (Van der Waals forces) or chemisorption
  • Reduction: e.g. removal of chlorine from water is based on chemical reduction reactions
  • Catalysis: activated carbon can catalyse a number of chemical conversions, or can be a carrier of catalytic agents (e.g. precious metals)
  • Carrier of biomass: support material in biological filters
  • Carrier of chemicals: e.g. slow release applications colourant: activated carbon's function in liquorice is its color
