Abstract: The present invention relates to a method and system for the continuous preparation of gasoline, kerosene, and diesel oil from waste plastics. The method comprises the steps of: subjecting a melt of the waste plastics to a first catalytic reaction in which the waste plastic melt is in contact with a nickel or nickel alloy catalyst to be dehydrogenated while being decomposed; subjecting the dehydrogenated and decomposed waste plastic melt to a fluid catalytic cracking, as a second catalytic reaction to produce a gasoline-based fraction at a high fraction; fractionating the cracked material into a gasoline-based fraction, a kerosene fraction, and a diesel oil fraction; and reforming the gasoline-based fraction to produce a high octane number gasoline. The present invention can apply to a small scale facility, not to apply to a large scale facility. Also, the present invention allows gasoline to be prepared from the waste plastics in a high fraction and an efficient manner, thereby contributing to resource reclamation and environment protection.
