Our group is able to carry out collaborative or contract research on utilisation of biomass and wastes based on the following key competencies:

  • selection and characterization of biomass (agricultural wastes) and wastes feedstocks,
  • design, construction and operation of experimental units based on fixed or fluid bed reactors,
  • development of kinetic and reactor models based on data obtained from the experimental units,
  • analytical methods for physical and chemical analysis of gaseous and liquid hydrocarbon mixtures (GC, GC/MS-CPERI)

Experience has been obtain and technology has been developed in various areas as described below:

  • Biomass and agricultural by-products flash and slow pyrolysis
  • Production of charcoal and biooil from forestry biomass pyrolysis
  • Agricultural wastes gasification for energy utilization to engines
  • Cleaning of waste gasification gas
  • Kinetic modeling and design of bench scale reactor
  • Follow up of pilot plant in pyrolysis
  • Used tires pyrolysis and utilization of residual carbon black
  • Active carbon production from tires pyrolytic char
  • Active carbon production from agricultural wastes pyrolytic char
 

 

Facilities available for research   Top

 

Experimental facilities and acquired instrumentation are:

  • analytical equipment for physical characterization of gas and liquid such as GC,GC-MS (CPERI)
  • bench scale biomass pyrolysis units,
  • a batch captive sample reactor heated by electrodes with a flexibility to various heating rates, with capacities of 0.1-1.0 gr of biomass
  • a fluidized bed reactor with capacity of 1 kg/hr
 

 

Strategic plans    Top

 

By taking in account the emerging environmental needs worldwide and especially the eventual substitution of hydrocarbons by bioenergy our plans in research are:

  • Valorisation of agricultural waste and by-products to energy and high added value material production
  • Use of energy from biomass gasification to engines
  • Production of post pyrolysis solid products from tires (black carbon, activated carbon)
  • Biomass gasification. Hydrogen production by direct gasification of solid biomass (agricultural residues) and catalytic upgrading of the syngas.
  • Thermochemical processes for the production of hydrogen from biomass for advanced energy systems based on fuel cells, with low contribution to net carbon dioxide emissions.
