Pyrolysisnoun

The decomposition of a material or compound due to heat, in the absence of oxygen or other reagents.

Gasificationnoun

The action of gasifying.

Pyrolysisnoun

transformation of a substance produced by the action of heat

Gasificationnoun

(chemistry) The process of transforming carbon-based materials into a mix of carbon monoxide and hydrogen that can serve as fuel.

Pyrolysis

Pyrolysis is the thermal decomposition of materials at elevated temperatures in an inert atmosphere. It involves a change of chemical composition.

Gasificationnoun

The act or process of converting into gas.

Gasificationnoun

the process of changing into gas;

‘coal gas is produced by the gasification of coal’;

Gasification

Gasification is a process that converts biomass- or fossil fuel-based carbonaceous materials into gases, including as the largest fractions: nitrogen (N2), carbon monoxide (CO), hydrogen (H2), and carbon dioxide (CO2). This is achieved by reacting the feedstock material at high temperatures (typically >700 °C), without combustion, via controlling the amount of oxygen and/or steam present in the reaction.
