Gasification
• Gasification is a process that converts carbonaceous materials into a gas mixture called synthesis gas or Syngas and is itself a fuel.
• Gasification is a method for extracting energy from many different types of organic materials

Gasification
• Made from any Biomass or carbon source
• Carbon material CO & H (syngas)
• Syngas may be burned directly in internal combustion engines
• Syngas can be used to produce methanol and hydrogen, or converted into synthetic fuel.

Gasification vs Combustion
• Combustion oxidizes materials in the presence of O2 to produce heat, H20 and CO2
• Gasification restricts O2 and produces CO and H2. Gasification operates at high temperatures & pressure (2,600°F & 1000psi)
• The gas is then burnt to produce energy and maintain the temperature of the reaction

Coal Gasification
• Widely used to create electricity
• Clean air act and emission restrictions are ending most burning of coal for electricity so now it is gasified

Wood Gasification
• Old technology replaced by cheap oil
• Seeing a resurgence
