▎ 摘  要

NOVELTY - Preparing high-efficiency catalytic carrier, comprises (a) mixing silicon dioxide, aluminum oxide, magnesium oxide, metal salt reagent and graphene to obtain a mixed material, where the mass ratio of silicon dioxide, aluminum oxide, magnesium oxide, metal salt reagent and graphene is (3-5):(2-2.5):(1-1.5): (0.1-0.8): (1: 1.5), the metal salt reagent is at least one of ferric nitrate, manganese nitrate, cerium nitrate and chromium nitrate, (b) adding water to submerge the mixed material, grinding upto the granularity of less than 200 meshes, filtering, and drying to obtain a mixed powder, (c) mixing the mixed powder, extruding and granulating, and aging for 2-3 hours to obtain a formed carrier, and (d) placing the formed carrier under an inert atmosphere, heating to 1400 degrees C at a heating speed of (5-8) degrees C/minute, maintaining the temperature for 3-5 hours, and naturally cooling to room temperature to obtain the high-efficiency catalytic carrier. USE - The method is useful for preparing high-efficiency catalytic carrier. ADVANTAGE - The method can improve the catalytic activity of the catalyst when the catalytic carrier is loaded with the catalyst. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for use method of high-efficiency catalytic carrier, comprising (1) immersing the high-efficiency catalytic carrier in a metal salt solution for 12-16 hours, filtering, where the solute of the metal salt solution comprises at least one of ferric nitrate, manganese nitrate, cerium nitrate and chromium nitrate, and the metal salt solution and the nitrate component in the metal salt reagent are different, and (2) placing the high-efficiency catalytic carrier under an inert atmosphere, heating to 400-500 degrees C at the heating speed of (5-8) degrees C/minute, maintaining the temperature for 3-5 hours, naturally cooling to room temperature, and repeating the step (1) and (2) until the load rate on the high-efficiency catalytic carrier is 5-20 %.
