NOVELTY - Desulfurizing granule comprises 100-110 pts. wt. activated carbon, 34-40 pts. wt. diatomite, 10-14 pts. wt. charcoal, 3-5 pts. wt. magnesium carbonate, 5-7 pts. wt. zinc oxide, 2-3 pts. wt. ammonia water, 1-2 pts. wt. ethyl alcohol, 1-2 pts. wt. cellulose ether, 1-2 pts. wt. trimethyl phosphoric acid, 3-5 pts. wt. polyacrylamide, 11-13 pts. wt. vermiculite powder, 4-6 pts. wt. auxiliary agent and suitable amount of water.    USE - As desulfurizing agent.    ADVANTAGE - The agent has good durability and prolonged contact time, and is prepared by simple method.    DETAILED DESCRIPTION - Desulfurizing granule comprises 100-110 pts. wt. activated carbon, 34-40 pts. wt. diatomite, 10-14 pts. wt. charcoal, 3-5 pts. wt. magnesium carbonate, 5-7 pts. wt. zinc oxide, 2-3 pts. wt. ammonia water, 1-2 pts. wt. ethyl alcohol, 1-2 pts. wt. cellulose ether, 1-2 pts. wt. trimethyl phosphoric acid, 3-5 pts. wt. polyacrylamide, 11-13 pts. wt. vermiculite powder, 4-6 pts. wt. auxiliary agent and suitable amount of water, where the auxiliary agent comprises 8-11 pts. wt. zirconite powder, 2-3 pts. wt. methane, 2-3 pts. wt. magnesium chloride, 1.5-2.5 pts. wt. sodium bicarbonate, 2-4 pts. wt. natural coke powder, 2-3.5 pts. wt. polyacrylamide, 2-3 pts. wt. cerium dioxide and 10-13 pts. wt. bamboo fiber. The auxiliary agent is prepared by drying the raw materials at 100-120 degrees C for 1-1.5 hours and crushing into 40-60 meshes powder, then adding water, stirring uniformly, placing the mixture in carbonization furnace of 400-500 degrees C for 2-3 hours, then cooling and grinding into 80-100 meshes powder, adding deer marsh soil and acetic acid solution, extracting the mixture for 1.5-2 hours, filtering the extract, adding water and obtaining slurry. An INDEPENDENT CLAIM is included for method of preparing the desulfurizing granule, which involves grinding the raw materials for 1.5-2.5 hours into 150-200 meshes sieve to obtain mixed powder, then adding magnesium carbonate, zinc oxide, trimethyl phosphoric acid, vermiculite powder and water, stirring uniformly to obtain slurry, then adding the remaining residual components, heating the mixture to 60-70 degrees C for 2-2.5 hours to obtain mixed slurry, then mixing the mixed powder, mixed slurry and auxiliary agent, and drying and granulating the mixture to obtain the product.
