NOVELTY - Natural gas combustion catalyst comprises 15-25 pts. wt. kaolin, 15-25 pts. wt. desulfurization powder, 15-25 pts. wt. far-infrared ceramic powder, 5-15 pts. wt. negative ion powder, 5-15 pts. wt. tourmaline powder, 2-8 pts. wt. alumina powder, 2-8 pts. wt. samarium powder, 2-8 pts. wt. palladium powder and 2-8 pts. wt. graphene powder. USE - Used as natural gas combustion catalyst. ADVANTAGE - The overall performance of the catalyst is excellent, and its energy-saving rate and reduction of harmful exhaust emissions are the highest, the raw materials are divided into three groups for high-temperature treatment separately, and those with the same treatment temperature are treated as a group for high-temperature treatment separately to reduce the time for catalyst preparation and benefit the quality of the catalyst. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the catalyst, comprising (1) taking 15-25 pts. wt. kaolin, 15-25 pts. wt. desulfurization powder, 15-25 pts. wt. far-infrared ceramic powder, 5-15 pts. wt. negative ion powder, 5-15 pts. wt. tourmaline powder, 2-8 pts. wt. alumina powder, 2-8 pts. wt. samarium powder, 2-8 pts. wt. palladium powder and 2-8 pts. wt. graphene powder, (2) mixing and stirring kaolin and alumina powder to form the first mixing component, (3) mixing and stirring far-infrared ceramic powder, negative ion powder and tourmaline powder to form the second mixing component, (4) mixing and stirring desulfurization powder, samarium powder, palladium powder and graphene powder to form the third mixing component, (5) mixing and stirring the first mixing component, the second mixing component and the third mixing component to obtain the total mixture, (6) mixing the total mixture with water and continuing to mix and stir to obtain water-mixed materials, (7) pouring the water-mixed material into the granulator to make granules, (8) placing the granules produced in the step (7) into the dryer, and drying the granules, and (9) taking number of particles dried in the step (8), and performing performance testing.
