Key Terms

Gasification
The process of converting organic or fossil-based materials into carbon monoxide, hydrogen, and carbon dioxide.

Example: Gasification is used to convert biomass into syngas.

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

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

Fixed Bed Gasifier
A type of gasifier where the feedstock remains stationary while gas flows through it.

Example: Fixed bed gasifiers are often used for small-scale applications.

Fluidized Bed Gasifier
A gasifier where the feedstock is suspended in a bed of hot particles, allowing for better mixing.

Example: Fluidized bed gasifiers are efficient for larger operations.

Entrained Flow Gasifier
A gasifier that uses high temperatures to convert feedstock into gas quickly.

Example: Entrained flow gasifiers are suitable for coal and heavy feedstocks.

Feedstock
The raw material used in the gasification process.

Example: Wood chips can serve as feedstock for gasifiers.
