DEVULCANIZED RUBBER, METHOD FOR ITS PREPARATION AND ITS USE AS AN ABSORBENT |
摘要 |
A process is provided for converting discarded rubber, e.g., rubber crumb, into absorbent material. The process comprises extruding a mixture of discarded rubber and oxidizer(s) under progressively increasing temperature to reach a temperature above 250 °C. The extrudate may undergo a secondary oxidation. The partially devulcanized granular rubber formed is useful as absorbent material for hydrocarbons, e.g., in remediation of contaminated soil and oil spills. |
