Abstract

This solution affords wasteless technology of the disposal of waste raw material resulting in the full use of the substances contained therein. The essence hereof rests in the fact that the waste organic raw material is added part by part into a coal load in the total quantity of 1 to 10 mass % thereafter subject to a coking process. The method of disposal is determined particularly for degraded used tyres and plastics.

Description

The invention relates to a process for the disposal of waste organic raw materials, in particular used tires and plastics.

So far, these substances have been disposed of by incineration, which only made use of the heat generated. Other combustion products were not utilized and contributed significantly to environmental contamination, in particular by carcinogenic substances. Incinerators of these substances required high-performance cleaning equipment, the construction of which meant high investment costs. Other methods of disposal of these substances by their re-utilization, for example by crushing and use for the production of insulating materials, are carried out to a limited extent and do not address the problem of disposal of most of these substances which cannot be recovered and reused.

These disadvantages are overcome by the process for the disposal of waste organic raw materials according to the invention, which consists in that the waste organic raw materials are added in portions to the coal charge in a total amount of 1 to 10% by weight and then subjected to a coking process.

The process according to the invention enables waste-free disposal of these substances and avoids air pollution in comparison with the prior art processes, without requiring special investment costs. An essential advantage of the process according to the invention is that during the coking process the produced coke is enriched with carbon, which is bound in the raw materials to be processed. There is also an increase in the yield of accompanying liquid chemical products based on aliphatic hydrocarbons, such as benzene, toluene and xylene, and the enrichment of coke oven gas with released aliphatic hydrocarbons, which are formed by decomposition of waste organic raw materials in the coal feed during coking.

As a specific embodiment of the method according to the invention, a method of disposing of used tires is discarded.

Example

These tires are divided into 4 to 8 parts, depending on their size, and when the prisms are tamped, they are added to the tamping box and the tamping hammers tamped into the coal charge. At a weight of 16,000 kg of coal prism, 16 kg of tires are treated in this way, corresponding to 1% by weight of the coal charge. Small, degraded tires, especially passenger car tires, can be added to the coal charge without cutting them into smaller pieces.

When disposing of plastic waste materials, these materials are first crushed and added continuously from a separate container to the coal charge, where they are mixed and mixed together with coal in a ramming process and filled into the coke chamber of the coke battery. % of plastics in the coal charge per 1% by weight.
