Abstract
Abstract A process and apparatus for feeding scrap tires into a reactor for the recovery of carbonaceous raw materials. The process comprises suspending the tires in a melt chamber having hot gases flowing therethrough at between 250 DEG F and 600 DEG F, allowing the hot gases to flow past the tires, melting the carbonaceous material therein, the melted material being fed into a reactor tube which converts the material to carbonaceous raw materials. The non-meltable portions of the scrap tires, such as metal beads or belted reinforcement, are separated in the melt chamber from the melted scrap tires.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
107 words
A process of feeding scrap tires into a reactor for the recovery of carbonaceous raw materials comprising: suspending the intact tires in a melt chamber on a cone shaped suspending member, the hollow center portion of said tires being positioned over the apex of said cone shaped member and said tires moving down said member during melting, said chamber having substantially inert hot gases flowing therethrough; allowing the hot gases to flow past said tires melting the carbonaceous material; feeding the melted carbonaceous material into a reactor tube which converts the material to volatile hydrocarbons; collecting in the melt chamber the non-meltable portions of the scrap tires.
Claim 2
Dependent Claim
107 words
A process of feeding scrap tires into a reactor for the recovery of carbonaceous raw materials comprising: suspending the intact tires in a melt chamber on a cone shaped suspending member, the hollow center portion of said tires being positioned over the apex of said cone shaped member and said tires moving down said member during melting, said chamber having substantially inert hot gases flowing therethrough; allowing the hot gases to flow past said tires melting the carbonaceous material; feeding the melted carbonaceous material into a reactor tube which converts the material to volatile hydrocarbons; collecting in the melt chamber the non-meltable portions of the scrap tires.
Claim 3
Dependent Claim
35 words
The process of claim 1 wherein the hot gas is fed into a hollow base of said cone shaped suspending member and out and past said tires through openings along the surface of said member.
Claim 4
Dependent Claim
124 words
A process of feeding scrap tires into a reactor for the recovery of carbonaceous raw materials comprising: feeding the intact tires into a melt chamber having a cone shaped suspending member; positioning the hollow, center portion of said tires over the apex of said cone shaped suspending member, said tires moving down said member during melting; feeding substantially inert hot gas maintained at between 250° F and 600° F into a hollow base of said cone shaped suspending member and out past said tires through openings along the surface of said member; feeding the melted carbonaceous material into a reactor tube which converts the material to hydrocarbon gases and a char by-product; collecting in the melt chamber the non-meltable portions of the scrap tires.
Claim 5
Dependent Claim
124 words
A process of feeding scrap tires into a reactor for the recovery of carbonaceous raw materials comprising: feeding the intact tires into a melt chamber having a cone shaped suspending member; positioning the hollow, center portion of said tires over the apex of said cone shaped suspending member, said tires moving down said member during melting; feeding substantially inert hot gas maintained at between 250° F and 600° F into a hollow base of said cone shaped suspending member and out past said tires through openings along the surface of said member; feeding the melted carbonaceous material into a reactor tube which converts the material to hydrocarbon gases and a char by-product; collecting in the melt chamber the non-meltable portions of the scrap tires.
Claim 6
Dependent Claim
17 words
The process of claim 3 wherein the hot gas is maintained between 350° F and 450° F.
Claim 7
Dependent Claim
22 words
The process of claim 3 wherein the hot gas is obtained from burning of the char by-product produced in the reactor tube.
