Abstract
The present invention relates to pellets or granules based on iron oxides and/or iron oxyhydroxides and iron(III) hydroxide, a unit suitable for the through-flow of a fluid medium at least partially filled with an adsorbent/catalyst in pellet form consisting essentially of iron oxide and/or iron oxyhydroxide embedded in an iron hydroxide matrix, processes for their production comprising filtering, drying and shaping steps and their processes of their use.
Claims16
A unit suitable for the through-flow of a fluid medium at least partially filled with an adsorbent/catalyst in pellet form consisting essentially of iron oxide and/or iron oxyhydroxide embedded in an iron hydroxide matrix.
A process for the production of an adsorbent/catalyst comprising the steps of
- (a) mixing an aqueous iron(III) hydroxide suspension into an aqueous suspension of iron oxide and/or iron oxyhydroxide, comprising Fe(OH)2 and then
- (b) either
- (b1) drying the suspension until it reaches a solid state and then mechanically comminuting the solid material to the desired shape and/or size,
- or
- (b2) mechanically shaping the suspension, optionally in the semisolid state after predrying, followed by additional drying until a solid state is achieved.
