Non-equilibrium plasma-assisted method and system for reformulating and/or reducing tar concentration in gasification derived gas product

A method for reformulating a raw gas from a gasification reaction comprising the steps of:

• a. removing particulates from the raw gas to obtain a particulate-free raw gas;
• b. delivering the particulate-free raw gas to a mixing chamber;
• c. injecting air pre-heated to a temperature of between 300-400° C. into the mixing chamber to obtain a mixture;
• d. maintaining the mixture in the mixing chamber for a residence time sufficient to raise the temperature of the mixture to about 650-950° C. by partial thermal oxidation to obtain a pre-heated mixture;
• e. contacting the pre-heated mixture with an electrical discharge such that a non-equilibrium plasma is formed, thereby producing a reformulated gas;
• and
• f. removing the reformulated gas from the chamber.
