> Test Facilities

A number of test facilities are in operation by BTG. These facilities are used for own technology developments, but are also available for contract research of third parties. For a more detailed explanation of the technologies, see technologies.

  • Pyrolysis pilot-plant
  • Fluidised bed gasification & Tar removal
  • Gasification of liquid feedstocks
  • Anaerobic digestion
  • Biomass conversion in supercritical water
  • > Pyrolysis pilot-plant

    Pilot plant (1 MWth) for the production of a clean, liquid fuel from biomass and residues.

    Capacity: 100 - 250 kg biomass/hour
    Product: 70 - 175 kg bio-oil/hour
    Feedstock examples: Wood, dried sludge, straw, tobacco,bagasse, etc
    Particle size: up to 6 mm (after sizing)
    Moisture content: up to 10 wt% (after drying)
    Typical runtime: 5 - 50 hrs
    Basic results: bio-oil, bio-oil yield, mass & energy balances, flue gas composition

    > Fluidised bed gasification & Tar removal

    Pilot plant installation to test the gasification of a diversity of feedstocks, gas cleaning, gas engine operation and electricity production.

    Capacity: 5 - 25 kg biomass/hour
    Product: producer gas/heat/electricity
    Feedstock examples: Wood, energy crops, agriculturalresidues, waste, dried manure, etc.
    Particle size: up to 15 mm
    Moisture content: up to 30 wt%
    Typical runtime: 2 - 10 hrs
    Basic results: gas yield, gas composition, tar content & composition, mass- & energy balance

    > Liquid fuel combustion chamber

    Small-scale test installation for the combustion of liquid fuels, blends or co-combustion with gaseous fuels to investigate combustion performance and flue gas emissions

    Capacity: 100 kWth
    Product: heat
    Feedstock examples: bio-oil, fatty acids, vegetable oils,animal fats
    Typical runtime: 1 - 4 hrs
    Basic results: heat production, combustion performance,emissions (NOx, CO, SOx)

    > Gasification of liquid feedstocks

    Test installation for the high temperature gasification of liquid feedstocks with air, oxygen or mixtures to produce a clean syn-gas.

    Capacity: 2 L liquid/hour
    Product: Syn-gas
    Examples of feedstocks: bio-oil, fatty acids, vegetable oils, animal fats
    Typical runtime: 1 - Biomass conversion in supercritical water4 hrs
    Basic results: gas yield, gas composition, tar content and composition

    > Anaerobic digestion

    Screening facility to test the applicability of different feedstocks under anaerobic digestion conditions to produce biogas.

    Capacity: 4 reactors parallel - 50 gr/reactor
    Product: biogas (CH4/CO2)
    Examples of feedstocks: manure, wet agricultural residues, vegetable oils and fats, wet waste
    Moisture content: 60 wt%
    Typical runtime: 20 - 30 days
    Basic results: gas yield, gas composition, mass balance

    > Biomass conversion in supercritical water

    Pilot-plant installation for the conversion of wet biomass and residues in supercritical water to produce Substitute Natural Gas (SNG) or Hydrogen.

    Capacity: 5 - 30 L/hr
    Product: (Compressed) Substitute Natural Gas - (C)SNG), /Hydrogen
    Feedstock examples: wet biomass and residues, glycerine,vinasse, manure, wine residues, etc.
    Moisture content: 70 - 95 wt%
    Typical runtime: 2 - 5 hrs
    Basic results: gas yields, gas compositions, mass balance
