Sorbing granular material and process for producing sorbing granular material

A device comprising:

• a filter insert comprising a container and a filling within the container, the filling comprising a sorbing granular material comprising:
• a sorbing raw material mass;
• and
• magnetizable particles, wherein the sorbing raw material mass is mixed at least partly with said magnetizable particles and granualized by shaping or punching the sorbing raw material to form particles of granular material, each including material of the sorbing mass and some of the magnetizable particles, and upon magnetization of said magnetizable particles, said particles of granular material form a compacted sorbing granular material form with a compaction being based on magnetic attracting forces between said magnetizable particles, wherein said compaction is reversible and a relative movement of the particles of granular material is limited by attractive forces between the magnetizable particles, whereby breathing gas flows through the compacted sorbing granular material, in an anesthesia apparatus or a closed-circuit respirator or a regeneration type respirator, and during gas flow through the compacted sorbing granular material, magnetic attracting forces act between magnetized particles of the granular material to limit a relative movement of the magnetized particles of the granular material and prevent or reduce a motion between particles of the granular material and between the particles of the granular material and a granular material container wall.

A device comprising:

• a filter/absorber insert comprising:
• a container comprising a container wall with a breathing gas inlet and a breathing gas outlet;
• a compacted sorbing granular material filling comprised of magnetized particles of granular material with magnetic attracting forces acting between the magnetized particles of granular material to define a compacted state of the compacted sorbing granular material within the container wall of the container, wherein the compaction is reversible, the particles of granular material comprising:
• a sorbing material;
• and
• magnetizable particles, wherein the sorbing material is mixed at least partly with the magnetizable particles and is granualized to form the particles of granular material particles having a diameter of from about 2 mm to 4 mm, with the compacted sorbing granular material filling having a form corresponding to the container wall of the container and a compaction of magnetized particles of granular material based on magnetic attracting forces between the magnetized particles of granular material, wherein the compaction is reversible and a relative movement of the magnetized particles of granular material is limited and a motion between the granular material and the container wall is prevented or greatly reduced by attractive forces between the magnetized particles of granular material, whereby breathing gas flows through the granular material filling form in an anesthesia apparatus or a closed-circuit respirator or a regeneration type respirator and during gas flow through the granular material filling form, magnetic attracting forces act between the magnetized particles of granular material to limit a relative movement of the magnetized particles of granular material and to prevent of reduce a motion between the granular material and a granular material container wall as the breathing gas flows through the granular material filling form.
