GASIFICATION REACTIONS
BY-PRODUCT USAGE
PARTICULATE REMOVAL
The feedstock reacts with oxygen to form hydrogen and carbon monoxide. Keeping the temperature high ensures complete conversion of all feedstock materials.
Inorganic materials from the coal are trapped in a glassy matrix resembling coarse sand. This inert material is referred to as slag, and has various uses in the construction industry. There is no ash waste from the gasification process.
A scrubbing system removes all particulates from the gas.
