Hydrocoprocessing of scrap automotive tires and a low-rank coal was carried out in a magnetically stirred autoclave. Reaction temperature (400 C) and time (30 min) were kept constant in every experiment, while different pressures (10, 5, and 1 MPa of H{sub 2} and 0.1 MPa of N{sub 2}) were studied. An iron-based catalyst was used to improve yields. Derived oils were analyzed by GC-MS and TLC-FID. In terms of yields, it is shown that there is a synergism between these two materials, although it can only be observed working at low hydrogen pressure. The oils obtained in the coprocessing showed a more aromatic nature than those obtained when both materials are processed alone, and higher boiling points, suggesting that radicals from rubber and coal react between each other instead of reacting with hydrogen radicals.
