Abstract

The invention relates to a method for producing insulating materials from mineral fibers, especially from glass and/or rock wool. A silicate melt is produced in a melting unit, especially a cupola melting furnace, and is disintegrated in a disintegration device to preferably microfine fibers.
Preferably, a binder and/or proofing agent is added to the fibers and they are placed on a conveyor means in the form of an unwoven material. The aim of the invention is to improve said method and said melt in such a manner that the method can be carried out at lower costs or that an inexpensive melt is provided by using inexpensive starting materials. To this end, the silicate melt is at least partially produced from catalysts derived from oil refining that are especially no longer useful.

Claims (21)

1. Method for producing insulating materials from mineral fibers, particularly from glass and/or rock wool, in which method a silicate melt is prepared in a melting unit, particularly a cupola furnace, and disintegrated in a disintegration unit to preferably microfine fibers, and preferably binders and/or proofing agents are added to the fibers, and the fibers are placed on a conveyor means in the form of an unwoven material, characterized in that the silicious melt is prepared at least partly from oil refining catalysts and particularly from those oil refining catalysts which are no longer usable.
2. Method according to claim 1, characterized in that as catalysts those from cracking and/or hydrocracking processes are used.
3. Method according to claim 1, characterized in that with zeolites the sodium content of the catalysts is reduced.
4. Method according to claim 1 characterized in that metals precipitated during the melting-open of the catalysts are collected and periodically drained.
5. Method according to claim 4, characterized in that the metals are collected and periodically drained together with metallic iron reduced from the raw materials.
6. Method according to claim 1, characterized in that the melt is prepared from the catalysts and the usual raw materials for the production of insulating materials from mineral fibers, particularly diabase, ba-salt and limestone as well as dolomite and/or raw materials obtained during pro-duction or recycling.
7. Method according to claim 1, characterized in that oxidic constituents contained in the melt, for example rare earths like La2O3, CeO2, Pr6O11 are dissolved.
8. Method according to claim 1, characterized in that fine-grained catalyst masses are pressed to lumpy bodies before they are melted open.
9. Method according to claim 8, characterized in that residual materials taken from the primary waste cycle and/or silicious stones used as supporting grain and/or binders, for example hydraulic cements, latent-hydraulic materials, lime and/or lignin and/or molasses are added to the fine-grained catalyst masses.
10. Method according to claim 9, characterized in that the constituents of the melt are mixed before they are fed to the melting unit.
11. Method according to claim 1, characterized in that the catalysts are blown through blast forming into the melting unit, particu-larly a shaft furnace, as a fine-grained mass.
12. Method according to claim 1, characterized in that the catalysts are preheated before they are fed to the melting unit.
13. Method according to claim 12, characterized in that the preheating temperature is 600° at maximum.
14. A melt for producing mineral fibers for a mineral fiber web, particularly from rockwool, which can be made into insulating materials, characterized by oil refining catalysts that are no longer usable.
15. A melt according to claim 14, characterized in that the catalysts originate from cracking and/or hydrocracking processes.
16. A melt according to claim 14, characterized in that the catalysts are mixed with residual materials from the primary waste cycle and/or recycling materials from the mineral fiber production.
17. A melt according to claim 14, characterized by 20 - 60% by weight of SiO2 and 10 - 60% by weight, particularly - 30% by weight of Al2O3.
18. A melt according to claim 14, characterized in that the catalysts have a grain size of between 2 and 6 mm, particularly between 3 and 4 mm.
19. A melt according to claim 14, characterized in that catalysts have a mean diameter of between 30 and 100 µm, preferably be-tween 50 and 70 µm.
20. A melt according to claim 14, characterized in that the catalysts are formed as extrudates, of which the length preferably is be-tween 1 and 5 mm, particularly between 2.5 and 3 mm.
21. A melt according to claim 14, characterized in that the catalysts include 10 - 30% by weight, particularly 15 - 25% by weight of metals like Ni or W, or 15 - 35% by weight, preferably 22- 28% by weight of CoO + MoO3.
