Reactor zone (A)

- Maximum temperature: 1500°C
- Pressure: 10-30 bar
Maximum thermal output: 150 kW

- Heating by oxycombustion of:
     - Natural gas (allothermal mode)
     - Biomass (autothermal mode)
- Mass flow: 10-50 kg/h
- Feedstock : raw or torrefied wood mixed with agricultural residues or non-hazardous wastes
     - Particle size: < 500 µm
     - Moisture: < 10%
- Injection carrier gas: N2 or CO2
- Reactive gas: O2, H2O, natural gas

Quench zone (B)

Water or solid injection quench
Slag collection at the bottom of quench zone


Wall and gas temperature measurement (thermocouple and pyrometer)
Mass flow measurement (solid et gas)
Measurement of major gas (CO, H2, H2O, CO2), minor gas and tar concentrations (tar protocol); tar measurement by SPA (Solid Phase Adsorption) sampling and quantification by gas chromatography
