Non-thermal micro-plasma conversion of hydrocarbons

A method comprising:

• providing, to a reaction zone:
• a hydrocarbon precursor material,
• a plasma forming material, and
• a plasma promoter material comprising solid particles dispersed within a gas flow;
• exposing, in the reaction zone, the received plasma forming material and the received plasma promoter material to microwave radiation, the dispersed solid particles of the plasma promoter material causing initiation of a non-thermal micro-plasma proximal to the plasma promoter material;
• upon conversion of the plasma forming material to the non-thermal micro-plasma, mixing the plasma forming material with the hydrocarbon precursor material;
• and
• exposing the hydrocarbon precursor material to the non-thermal micro-plasma and the microwave radiation, the exposure of the hydrocarbon precursor material selectively converting the hydrocarbon precursor material to a product including a carbon enriched material and a hydrogen enriched material.
