Homework Statement

Difference between pyrolysis and gasification

Relevant Equations

none

Pyrolysis-:

Gasification-:

what's the difference between these two? i have in my notes that gasification uses partial air but pyrolysis uses no air. but in this figure gasification uses steam pipe...whereas pyrolysis uses air pipe. I can't understand what is going on.

Those diagrams are unreliable. That is not a “cyclotron”, it is actually a “cyclone separator”.

Pyrolysis incompletely burns organic material with oxygen from the air, producing CO2 and H2O exhaust gas.

Gassification does not provide oxygen to complete the combustion, but extracts the hydrocarbon and carbon monoxide as “producer gas” for later reaction or use as a fuel.
