Abstract: A process for extracting fuel products from waste rubber, comprising the steps of subjecting the waste rubber to pyrolysis to produce a pyrolysis vapour, subjecting the pyrolysis vapour to a condensation step to produce a pyrolytic oil having a boiling point range of 45-400° C. and a flash point below 25° C., and then subjecting the pyrolytic oil to a vacuum steam stripping step so as to recover a fraction having a flash point of at least 40° C. but no higher than 55° C., a boiling point range starting at 100° C. or higher, a density at 15° C. of less than 990 kg/m3, a total acid number TAN of up to 12, a styrene content of less than 7000 ppm, and an organic halogen (as Cl) content of less than 50 ppm.
