DEPOLYMERIZATION PROCESS FOR PRODUCING OFF-SPEC CRUDE AND CARBON BLACK FROM SCRAP TIRES

摘要

The present invention provides an economical process for the producing of off-spec crudes and carbon black from vulcanized rubber chips, derived from scrap tires. The process comprises the de-polymerization of rubber chips by breaking down the number of carbon atoms in molecules. The de-polymerization process utilizes endothermic heat to decompose the long chain polymers of rubber chip into short petroleum hydrocarbon. The vulcanized rubber chip is de-polymerized into an off-spec crudes hydrocarbon vapor and solid residue.
