Abstract:
1. A carbonous residue for capturing mercury made by the process to recycle tires comprising: digesting the tires in a fired heater at a maximum temperature below about 750 degrees Fahrenheit using an oil being selected from the group consisting of residuum, waste motor oil, new 600 w cylinder oil, trim gas oil, vacuum heavy bottoms, decanted oil, light catalytic cycle oil, and combinations thereof; separating the gaseous component from said tires by using a separator; separating glass and steel fibers from said tires by using a horizontal screw reactor housed in a non-spherical chamber; adding a product-enhancing additive which increases the halogen content in the carbonous residue, said product-enhancing additive being selected from the group consisting of compounds of bromine, chlorine, fluorine, iodine, and combinations thereof; retorting at a maximum temperature below about 875 degrees Fahrenheit, thereby obtaining a carbonaceous material; and curing said carbonaceous material at a maximum temperature below about 1200 degrees Fahrenheit thereby obtaining said carbonous residue; wherein said product-enhancing additive produces a carbonous residue comprising 0.2% to about 5.0% halogen by weight.
