Catalyst for removing carbonic oxide in flue gas and preparation method thereof

The invention discloses a catalyst for removing carbonic oxide in flue gas. According to the catalyst, biomass activated carbon is used as a carrier and is loaded with an active component gold micronflower; granularity of the biomass activated carbon is 0.25 to 0.425 mm; the active component gold micron flower is 0.4% to 2.5% of the mass of the carrier; and the biomass activated carbon is prepared by using coconut shell as a raw material. The catalyst has high activity at low temperature; and the preparation technology has advantages of mild condition, simple method, safe operation and easy implementation. 本发明公开了种脱除烟气中氧化碳用催化剂，该催化剂以生物质活性炭为载体，其上负载有活性组分金微米花；生物质活性炭的粒度为0.25-0.425mm；活性组分金微米花为载体质量的0.4%-2.5%；生物质活性炭以椰子壳为原料制备得到。本发明制备得到的催化剂在低温下具备较高活性，且制备工艺条件温和，方法简单，操作安全，易于实施。
