Description

[0001] The present invention relates to a hydrocarbon reforming system using Steam Plasma,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a hydrocarbon reforming system using steam plasma, and more particularly, to a hydrocarbon reforming system for reforming a steam plasma and a hydrocarbon body to produce synthesis gas.

Generally, a steam reforming reaction, which is a reforming method in which a hydrocarbon such as methane is reformed to produce a synthesis gas such as hydrogen and carbon monoxide, provides a high hydrogen generation efficiency as compared with other reforming reactions, .

However, in the case of the conventional wet reforming method, in the case of poor thermal management, deterioration of the catalyst occurs at the time of formation of the high temperature, so that the performance is deteriorated and a large amount of carbon is generated and adsorbed on the catalyst, There is a problem that the system becomes complicated because it requires strict heat maintenance and management for maintaining the catalyst activation temperature due to the endothermic reaction.

Further, when a catalyst of a non-noble metal material is used, the cost of the device can be reduced, but a separate reduction process is required. In the case of using a noble metal catalyst, the reduction process can be omitted, The cost is increased. In addition, when the fuel contains impurities such as sulfur, the active area is drastically lowered due to the poisoning of the catalyst.
