US Patent:

6833485, Dec 21, 2004

Filed:

Aug 9, 2001

Appl. No.:

09/925401

Inventors:

Ronald E. Nichols - Evergreen CO
Alan M. Levine - Monroeville PA
Jules E. Langlois - New Kensington PA

Assignee:

RJ Lee Group, Inc. - Monroeville PA

International Classification:

C07C 406

US Classification:

585241, 208106, 208125, 208126

Abstract:

A low energy method of pyrolysis of rubber or other hydrocarbon material is provided. The hydrocarbon material is heated while maintaining a vacuum, using a clay catalyst. In an additional embodiment, also under a vacuum and optionally with or without the catalyst, the temperature of the reaction chamber and corresponding fuel input is varied either over time or spatially within the reaction chamber, to take advantage of the exothermic properties of the reaction. With the method of the present invention, an improved solid reaction product can be achieved.

Appl. No.:

12/082523

Inventors:

Daniel Eric Steinmeyer - Chesterfield MO, US
Alan Marc Levine - Monroeville PA, US
James Matthew Williams - Latrobe PA, US

Assignee:

Chem Engineering Energy, LLC - Chesterfield MO

International Classification:

C08G 1/14
C08L 69/00

US Classification:

528489, 528488, 525439

Abstract:

A method of making a metal-terephthalate polymer from polyester ethylene terephthalate includes reacting polyester ethylene terephthalate with a metal compound in a non-aqueous melt environment at an elevated temperature. The elevated temperature will be greater than 270 C. , and preferably rises to a temperature of about 520 C. The method is preferably carried out at a low pressure. The method may be used in the recycling of passenger vehicle tire shreds to produce a carbon black rrich ppowder that is enriched in the metal-terephthalate polymer.

Abstract:

A method for controlling volatiles in recycled carbon black, such as from pyrolysis of tires, includes deagglomerating the recycled carbon black to substantially reduce the carbon black particle size and impinging an air current on the carbon black particles, preferably in a countercurrent direction, to increase the processing temperature and thereby enhance the release of volatiles. Associated apparatus is disclosed.
