Abstract: Disclosed herein is a surface treatment method of a ceramic powder using microwave plasma in order to enhance flowability. The surface treatment method can be applied to a ceramic powder having a small particle size of 45 μm or less and can significantly enhance flowability while reducing an influence on a particle size compared to a conventional method. Consequently, the ceramic particles surface-treated by the above-described surface treatment method can be formed to have a smooth and dense coating film without pores during spray coating.

Abstract: The present invention provides a hybrid reforming system for producing syngas through a reforming reaction between carbon dioxide plasma and a hydrocarbon material, the system comprising: a carbon dioxide feeder (110) which feeds carbon dioxide; a hydrocarbon material feeder (120) which feeds the hydrocarbon material; a plasma reformer (200) which respectively receives carbon dioxide and the hydrocarbon material from the carbon dioxide feeder (110) and the hydrocarbon material feeder (120), and produces primary syngas through a reforming reaction while producing the carbon dioxide plasma using electromagnetic waves; a wet carbon-refining device (130) which is arranged at a gas exhaust end of the plasma reformer (200) and filters and refines carbon contained in the primary syngas; and a catalyst dry-reformer (140) which is arranged at a gas exhaust end of the wet carbon-refining device (130) and produces secondary syngas by making the refined syngas undergo a catalyst dry-reforming reaction.
