Abstract:
1. A pelletized tire pyrolysis product, comprising: a carbon black product in an amount greater than about 85 percent by weight relative to the total weight of the pelletized tire pyrolysis product, the carbon black product formed from a carbonaceous char derived from pyrolysis of at least one of whole tires and tire shreds, the whole tires and the tire shreds having steel belt wire and zinc from zinc oxide present in tire rubber compounds, the carbon black product further comprising: a binder oil that agglomerates the carbon black product into substantially free-flowing pellets, wherein the binder oil is derived from the pyrolysis of the at least one of the whole tires and the tire shreds and has an iron content and a zinc content, wherein individual pellets of the pelletized carbon black product have an average diameter from about 0.125 inches to about 0.0625 inches, wherein an ASTM D3191 standard styrene butadiene rubber formulation with the carbon black product has a tensile strength between 2800 psi and 3500 psi, and wherein the carbon black product is pulverized to about a 325 mesh particle size, with 99.99% of the pulverized carbon black product able to pass through a 325 mesh screen, prior to combining the carbon black product with the binder oil into the substantially free-flowing pellets.
