Abstract
An ordered packing for mass transfer and heat exchange processes includes pre-formed individual parts. The packing is formed of carbon fiber-reinforced carbon with carbon fibers or carbon fiber yarns, which are linked one with the other by way of textile bindings, as a filler and of a matrix carbon, preferably based on synthetic resins.
Claims18
An ordered packing assembly for columns or reactors for mass transfer and heat exchange processes, comprising
- an ordered packing built up from pre-formed individual parts,
- said pre-formed individual parts being built up from
- thin plates of matrix carbon formed from a matrix precursor and being reinforced with a filler of carbon fibers being present in carbonized form prior to contacting with said matrix precursor, said plates having perforations formed therein with a clear width of substantially from 10 to 5,000 .mu.m and having a profile and lower and upper surfaces;
- said filler of carbon fiber-reinforced carbon being selected from the group consisting of continuous carbon fibers and carbon fiber yarns interlinked with textile bindings;
- said filler being present in the form of planar structures disposed in said plates in single layers and parallel to said upper and lower surfaces of said plates
- said pre-formed individual parts being held together by elements selected from the group consisting of carbon and carbon fiber reinforced carbon.

- an ordered packing built up from pre-formed individual parts.
- said pre-formed individual parts being built up from
- thin plates of matrix carbon formed from a matrix precursor and being reinforced with a filler of carbon fibers formed from a fibrous precursor and having been made infusible by thermal processing prior to contacting with said matrix precursor, said plates having perforations fromed therein with a clear width of substantially from 10 to 5,000 .mu.m and having a profile and lower and upper surfaces;
- said filler of carbon fiber-reinforced carbon being selected from the group consisting of continuous carbon fibers and carbon fiber yarns interlinked with textile bindings;
- said filler being present in the form of planar structures disposed in said plates in single layers and parallel to said upper and lower surfaces of said plates.
- said pre-formed individual parts being held together by elements selected from the group consisting of carbon and carbon fiber reinforced carbon.
