The invention discloses a light
acrylic acid catalyst carrier which is prepared from the following components: 10-20wt% of
bauxite, 3-5wt% of Hunan Pukou sands, 3-5wt% of hemi-mountain mud, 30-40wt% of pseudo-
boehmite, 10-20wt% of Jiangxi East Bridge sands, 10-30wt% of kaolin and 10-20wt% of
wood flour. The preparation method comprises the following steps of performing ball milling and mixing on the
bauxite, the Hunan Pukou sands, the hemi-mountain mud and half of the kaolin to obtain a uniform base material, and then lining the base material to prepare a
green body; and then performing ball milling and mixing on the pseudo-
boehmite, the Jiangxi East Bridge sands, the
wood flour and half of the kaolin to obtain a uniform facing material, then adding the facing material in a ball milling
machine for continuously lining to prepare
pellets, adding non-metallic compound
crystal particles in the ball milling
machine, spraying the surface of each pellet with a layer of
colloid, and then performing high-temperature firing on the
pellets to prepare the light
acrylic acid catalyst carrier. The light
acrylic acid catalyst carrier is large in water absorption, small in
specific gravity, largein specific surface area, strong in adsorption force, simple in technology and low in cost.
