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.:

09/975476

Inventors:

Ronald Nichols - Evergreen CO, US

International Classification:

C10B047/00
C10B049/00
C10B051/00
C10B053/00
C10B055/00

US Classification:

201/001000

Abstract:

An apparatus for vacuum pyrolysis of rubber and/or other hydrocarbon material is provided. The apparatus includes tandem batch feed hoppers operated sequentially under vacuum to continuously feed the pyrolysis reactor, and tandem batch collection bins operated in sequence under vacuum to collect the reaction product from the reactor. A process for vacuum pyrolysis is also provided.
