Embodiment 1
[0025] Use aluminum hydroxide and commercially available coconut shell activated carbon as raw materials to prepare activated alumina composite activated carbon material. HNO 3 For the binder:
[0026] Preparation steps:
[0027] (1) Mixing: put the aluminum hydroxide and coconut shell activated carbon powder into the mixer after weighing according to the proportion, and mix for 1 hour.
[0028] (2) Granulation: Put the mixed powder into a granulator, and gradually spray 13wt% dilute HNO 3 350 grams of the solution were granulated.
[0029] (3) Stale: Seal the granulated powder in a plastic bag and store it in a cool place for 24 hours.
[0030] (4) Molding: make spherical particles of 3-10 mm.
[0031] (5) Drying: Put the formed granules in the room to dry.
[0032] (6) Sintering: bury the dried particles in the pre-prepared atmosphere protection sand (graphite:river sand ratio 1:1), put them into the kiln for sintering, heating rate: 200℃ / h The heating rate was raised...
