FILTERING STRUCTURE COATED WITH CATALYST FOR REFORMING SYNTHESIS GAS AND FILTERING METHOD USING THE SAME

摘要

Disclosed herein is a filtering structure, including: a filtering medium for removing impurities from gas produced by gasifying coal or biomass; and a catalyst for converting methane and carbon dioxide into synthesis gas by a dry reforming reaction and a steam reforming reaction, wherein the filtering device is coated with the catalyst. The filtering structure is advantageous in that an additional process of separating and treating greenhouse gas, such as carbon dioxide, methane or the like, is not required, so that additional treating facilities are not required, thereby reducing additional costs. Further, the filtering structure is advantageous in that the amount of the discharged carbon dioxide, methane or the like can be reduced, thus providing an environment-friendly effect.
