Key Terms

Gasification
The process of converting solid or liquid fuels into gas.

Example: Gasification of biomass produces syngas.

Fluidization
The process of making solid particles behave like a fluid by passing gas through them.

Example: In a fluidized bed, sand particles float on air.

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

Example: Syngas can be used to produce electricity.

Bubbling Fluidized Bed
A type of fluidized bed where bubbles form and rise through the bed of particles.

Example: Bubbling fluidized beds are common in coal gasification.

Thermodynamics
The study of energy transformations and the laws governing them.

Example: Thermodynamics helps in understanding gasification efficiency.

Reaction Kinetics
The study of the rates of chemical reactions.

Example: Reaction kinetics is important for optimizing gasification processes.
