However, when incinerated, polymeric materials generally generate a large amount of heat, damage the furnace wall, generate harmful gases, and recover energy at best as steam or hot water. However, there is a problem in that energy is not flexible and the location of the incinerator is limited. Pyrolysis produces useful components,
The method of recovery is considered to be a preferable method from the viewpoint of effective use of resources, but it is complicated to purify and dispose of by-produced gas and to purify poorly decomposed oil to the extent that it can be used as fuel oil. Equipment and huge cost,
Financially difficult. In addition, although various studies have been made on plastics having good biodegradability, they have not reached the scope of research and development and have not been practically put into practical use in terms of cost.

Is particularly preferable because it does not mix. However, a polymer material containing chlorine or fluorine, or a material having an amide bond (-NHCO-) produces a harmful corrosive gas as a by-product during decomposition, and causes corrosion of the device and deterioration of the quality of decomposition products. Because it may cause
Measures such as anti-corrosion in the equipment and purification process of decomposition products are required. Further, since silicon-based polymer compounds such as silicone resin and silicone rubber contain oxygen and silicon, the yield of cracked oil is low and the quality of coke is deteriorated, so that they are not suitable for the method of the present invention.

The amount of the polymer material to be treated depends on the properties of the polymer material, the conditions of the coker to be used, the method of supplying the polymer material,
The amount may be appropriately determined based on the quality conditions of coke and cracked oil. That is, it can be determined in consideration of the properties of the polymer material and the heavy hydrocarbon oil, or by carrying out a test operation within the allowable range of product quality conditions and equipment conditions. Preferably, the polymer material may be supplied in a proportion of 80% by weight or less and the heavy hydrocarbon oil in a proportion of 20% by weight or more by the above-mentioned suitable feeding method and treated. The smaller the throughput of the polymer material, the less the influence on the product quality when the apparatus or the heavy hydrocarbon oil alone is used as a raw material is naturally small, but this is not the intention of the present invention. However, when the polymer material exceeds 80% by weight, when it is supplied as a mixed slurry with a heavy hydrocarbon oil, its fluidity decreases, and it is supplied as a mixed melt of the polymer material and the heavy hydrocarbon oil. In that case, it is difficult to maintain the uniformity and smooth supply to the coker becomes difficult, which is not preferable. When preliminarily charged into the soak drum, it is possible to adjust the charging amount of the polymer material so that the amount of heat carried in by the heavy hydrocarbon oil is insufficient and the polymer material that is not decomposed remains. preferable.

As described above, the cracked gas obtained by treating the polymer material with the heavy hydrocarbon oil in the coker,
And cracked oils are rich in olefinic components, similar to those obtained in normal coker operation. These are (1) immediately self-consumed as fuel, (2) recovering useful components as a raw material for petrochemicals, or (3) hydrorefined and used as petroleum products, or as a blend base material thereof, etc. The post-treatment can be carried out by the above method or a combination of these methods. These post-treatments can be extremely easily performed by using a petroleum refining apparatus that performs hydrogenation, desulfurization, denitrification, gas refining, fractional distillation and the like. Moreover, since the coker is often installed in the refinery or in close proximity to the oil refining equipment, it is convenient to use the existing equipment for the post-treatment. No cost is required, and the cost of the entire processing method of the present invention can be significantly reduced. Concretely speaking about this post-treatment, cracked gas can be used to recover useful components in a distillation column or consumed as fuel in a petroleum refining heating furnace, and cracked oil can be hydrorefined in a hydrorefining device and used for distillation, etc. The quality of the petroleum product or its blending base material can be easily improved by fractional distillation.

Another feature of the invention appears in this coke. That is, the texture of the coke obtained from the polymer material has a mosaic shape. On the other hand, the coke obtained from Middle Eastern residual oil and Southern residual oil has a flow structure as a main component and a mosaic structure in part. Further, depending on the carbon product using coke as a raw material, coke in which the mosaic structure is appropriately mixed in the flow structure is desired. According to the present invention, the mosaic structure in the coke can be easily controlled by adjusting the proportion of the polymer material as the coke raw material, so that the above-mentioned requirements can be met.

As described above, in the treatment method of the present invention, the organic polymer material is used as it is in the existing coker generally arranged in the petroleum refining facility, and the heavy oil which is the raw material oil is used. It can be carried out by utilizing an existing process together with the hydrocarbon oil, and the post-treatment of each cracked product can similarly use the existing equipment / process. Therefore, it is possible to recover useful components from plastic wastes and utilize them as recycled resources without newly establishing a waste treatment facility subject to restrictions such as location conditions. Since existing equipment and existing processes can be used as they are, it can be performed easily and at low cost. In addition, the method of the present invention can easily control the texture of the coke obtained.
