Key Terms

Gasification
The process of converting solid biomass into gas by heating it in a low-oxygen environment.

Example: Gasification allows for the production of syngas from wood chips.

Biomass
Organic material derived from plants and animals used as a renewable energy source.

Example: Corn stalks and wood pellets are common biomass feedstocks.

Syngas
A mixture of hydrogen and carbon monoxide produced from gasification.

Example: Syngas can be used to generate electricity or produce synthetic fuels.

Tar
A byproduct of biomass gasification that can clog engines and reduce efficiency.

Example: High tar content in syngas can lead to operational issues in engines.

Downdraft
A type of gasifier design where air flows downward through the biomass.

Example: Downdraft gasifiers are known for producing cleaner syngas.

Feedstock
Raw material used in the gasification process.

Example: Wood chips serve as feedstock in many gasification systems.
