Gasification turns biomass or any other carbonous material into synthesis gas (syngas, product gas), a mixture of carbon monoxide (CO), hydrogen (H2) and carbon dioxide (CO2). Gasification occurs by reacting organic material at high temperatures (>700 °C), without combustion and with an optimized amount of oxygen.
To achieve acceptable rates of bioconversion (such as biomethanation) gases fed into bioreactors need to be tar-free. Our unique oxygen-enriched gasifier produces highly pure, tar-free syngas. A high operation temperature (>1000 °C) also ensures an efficient decomposition of other harmful substances.
Syngas created in the gasifier can either be used as such, or upgraded into biomethane with our biomethanation technology.
While syngas is a valuable fuel in itself, biomethane has a far wider range of applications and is suitable for use in the existing natural gas infrastructure.
Certain micro-organisms are capable of performing a water-gas shift reaction (CO + H2O ⇌ CO2 + H2) under anaerobic conditions at an ambient temperature and pressure. Q Power has extracted a culture of such organisms and uses them in a patented bio-based syngas upgrading technology. CO2 and H2 created are fed into our biomethanation process to create synthetic methane (CH4 ).
The Q Power process involves a biological conversion of carbon to value-added products through gas fermentation. Carbon-rich waste gases and residues are transformed into biohydrogen and biomethane, providing a novel approach to carbon capturing and reusage.
