A process for the preparation of fuel oil, fuel gas and pyrolysis coke by pyrolysis comprising mixing waste rubber, waste synthetic resin, brown coal and bentonite at the ratio of brown coal 48.5 parts, synthetic resin 24.2 parts, rubber 24.2 parts and bentonite 3.1 parts by weight, and generally heating the above mixtures in a pyrolysis reactor while continuing to convey the mixture in the pyrolysis reactor until at the exit of the reactor, the temperature is in the range of 600°-700° C., thereby producing fuel oil, fuel gas, and coke without melted residue of pyrolysis reaction attaching on the surface of the reactor as a solid form.
