ABSTRACT:
A method for producing synthetical oils and storable products of calorific energy, by co-processing waste rubber materials, especially waste tires, and coal optionally in the presence of a material containing Fe as a catalyst, comprising the steps of mixing triturated waste rubber material having a particle size of preferredly 1-5 mm, and coal having particle sizes of 0.2-1 mm, and, when used, the catalyst having a referred particle size of 0.05-0.015 mm, until obtaining a mixture, heating the mixture in a reactor to a temperature between 300.degree. C. and 500.degree. C., during 3-180 minutes, at a pressure between atmospheric pressure and 10 MPa, to enable a processing step basically consisting of a pyrolysis/hydropyrolysis. During the processing step, there is a generation of gases containing approximately 50% CO and CO.sub.2, and approximately another 50% by volume of C.sub.1 -C.sub.4 hydrocarbons, and having a calorific energy between 6000 and 8000 kcal/Nm.sup.3, the gases being collected whereas the material resulting from the reaction is a mixture of solids and liquids which is subjected to extraction with organic solvents whereby an extract and a solid first residue are obtained, the solid first residue having a calorific energy between 4500 and 5000 kcal/kg, whilst by subjecting the extract to fractionation, an asphaltene residue having high calorific energy as well as synthetic oils are obtained from the extract.
