A novel carbon-based desulphurization catalyst and a preparation method thereof

The invention discloses a novel carbon-based desulphurization catalyst and a preparation method thereof. The carbon-based desulphurization catalyst is prepared from following raw materials by weight: 1-30 parts of cerium-zirconium solid solution powder, 100 parts of coal powder and 40-60 parts of an adhesive. The cerium-zirconium solid solution comprises cerium, zirconium, and at least one selected from yttrium, lanthanum, iron, cobalt and nickel. The preparation method includes: adding the cerium-zirconium solid solution powder, the coal powder and the adhesive into a kneader, uniformly mixing, kneading, adding the mixture into an extrusion moulding machine and moulding, drying, charing at 400-600 DEG C, and activating at 800-1000 DEG C by utilization of at least one of water vapor, carbon dioxide and water gas as an activating agent to obtain the novel carbon-based desulphurization catalyst used for flue gas desulphurization. The novel carbon-based desulphurization catalyst has characteristics of high desulphurization capability, large sulfur capacity, no desulphurization capability reduction caused by active component loss, wide applicable flue gas temperature range, and the like.
