Process of Biomass Gasification


  • Feedstock Preparation

Biomass feedstock starts as plant matter. It’s chopped, ground, and sorted. The aim is to make the feedstock uniform.

  • Drying Stage

Feedstock undergoes drying. Under 105-110 degrees Celsius, moisture evaporates. Optimum moisture content is below 20%.

  • Pyrolysis Phase

At 200-300 degrees Celsius, biomass starts decomposing. Volatile substances get released. What remains is char, a form of carbon.

  • Combustion Stage

Char and volatile substances do burn in controlled oxygen. The result is heat, along with carbon dioxide and water vapor.

  • Reduction Phase

With limited oxygen, carbon dioxide and water vapor turn into carbon monoxide and hydrogen. These are part of the final product, syngas.

  • Gas Cleanup

Impurities like tar and ash particles get removed from syngas. Purification ensures the gas is suitable for energy conversion.

  • Cooling Process

Hot syngas undergoes cooling. Drop in temperature condenses the water vapor, which gets separated from the gas.

  • Gas Conditioning

Conditioning entails altering the syngas composition. Adjustments ensure the gas meets required specifications for further applications.

  • Syngas Production

Carbon monoxide and hydrogen form the bulk of syngas. Other constituents include methane, nitrogen, and trace amounts of impurities.

  • Energy Recovery

Syngas carries high energy content. It’s converted into electricity or biofuel in power generation units.
