Patent for Sale:

Recycling of Used Tires and Carbon Black    

Breaking down scrap tires to various end products.


The patents outline the pyrolysis process to reclaim the carbon materials:

- shredding tires into shreds of less than two inches.
- pyrolysing the shreds to a char.
- drawing off volatile organics from the chamber reaction.
- removing the char from the reaction chamber.
- milling and sizing the pyrolytic carbon particles.
- using the pyrolytic carbon black in a polymerization process to produce recycled rubbber.
- produce pyrolytic carbon black of high purity.

Patent Summary

U.S. Patent Classes & Classifications Covered in this listing:

Class 423: Chemistry Of Inorganic Compounds

This class provides for what is generally termed the field of inorganic chemistry. It includes inorganic compounds, nonmetallic elements and processes of producing the same involving a chemical reaction. The products are generally in a relatively pure state but may be a mixture with no other utility than as a source material for an inorganic compound or element. This includes metal compound products useful in metallurgical processes of obtaining free metals.

Subclass 445R: Elemental carbon
Subclass 449.1: Carbon black (e.g., lampblack)
Subclass 449.2: Treating carbon black
Subclass 449.6: Utilizing synthetic polymer as reactant
Subclass 449.7: Tire
Subclass 461: Recovery or purification

Class 110: Furnaces

Solid material combustion apparatus: with or without the capability of utilizing auxiliary gaseous or liquid fuel; convertible to a gaseous or liquid fuel combustion apparatus; subcombinations and structure not provided for elsewhere. Combustion apparatus for incinerating solid or liquid refuse. Methods of operating solid material combustion apparatus not provided for elsewhere.

Subclass 104B: Burners, per se

Class 422: Chemical Apparatus And Process Disinfecting, Deodorizing, Preserving, Or Sterilizing

This is a generic class for (1) processes of disinfecting, deodorizing, preserving or sterilizing and (2) apparatus for (a) carrying out chemical reactions, (b) preparing or treating chemical compounds or compositions even though only a physical reaction is discernible, (c) performing an analysis which involves either a chemical reaction or a physical reaction not elsewhere provided, for and (d) carrying out the above processes not elsewhere provided for.

Subclass 150: Pigment or carbon black producer
Subclass 156: With plural sequential reaction zones or chambers
Subclass 164: Solid reactant type (i.e., absence of fluid reactants)

Class 521: Synthetic Resins Or Natural Rubbers -- Part Of The Class 520 Series

Part of the Class 520 Series - some general types of subject matter include: Solid synthetic resins, per se, regardless of utility; processes of preparing a synthetic resin involving a chemical reaction; reactable compositions which form a product; processes of purifying a solid synthetic resin or composition containing a synthetic resin by a chemical or physical process; process of reclaiming or recovering a solid synthetic resin; processes of treating a synthetic resin or specified intermediate condensation product with a reactant, or product thereof; blends of solid synthetic resins, processes of preparing or treating such blends; chemically reacted solid synthetic resins or processes of preparing; potentially reactable compositions which contain a solid synthetic resin or SICP and products of such a reaction, or processes of preparing; room vulcanizable potentially reactive compositions which merely require moisture and which are usually activated by heat and/or pressure to form a product; compositions of a nonreactant material and a solid synthetic resin or SICP; compositions containing a structurally defined material which is dispersed in a matrix which is not identified by overall dimension or some structure or processes of preparing; single-layered products containing a solid synthetic resin or composition thereof reciting no structure or dimension, or a fiber, filament, etc., which is no more than the material from which it is made, nonstructured single-layered web or sheet is encompassed; particles or a powder, per se, of a solid synthetic resin or composition thereof for which particles or powder no dimensions are recited; reactable compositions which form a product proper for this class and contain a photoinitiator or photosensitizer which are activated by wave energy or processes of preparing.

Subclass 40.5: Process of treating scrap or waste product containing at least one polymer derived from ethylenic unsaturated monomers only
Subclass 41: Treating rubber (or rubberlike materials) or polymer derived from a monomer having at least two ethylenic unsaturated moieties
Subclass 45.5: Treating with mechanical action and in the absence of a chemically reactive additive or solvent

Class 585: Chemistry Of Hydrocarbon Compounds

This class provides for a hydrocarbon compound in a pure or relatively pure state and for certain compositions containing hydrocarbons. Methods for making such compounds and compositions by synthesis, blending, etc., and certain methods for treating are also included. As applied to chemistry and chemical engineering this ordering is: materials defined by structure; compositions or mixtures; compounds or elements; manufacturing processes, e.g., synthesis; nonmanufacturing processes, e.g., purification; manufacturing apparatus; nonmanufacturing apparatus;

Subclass 241: From synthetic resin or rubber
