Problems solved by technology

None of the methods are efficient and convincing enough in not only removing the residue but also gaining further (in this case vigorous) use of the residue, secondary use of which is doing us a huge disservice now

Embodiment

[0115] The following table shows the results obtained for different recycling methods using different starting materials:

[0116] 1.- Thermal decomposition of plastic or rubber without fillers: Yield: 98%

[0117]

[0118] 2.- Thermal decomposition of filled plastics: Yield: 98%

[0119]

[0120] 3.- Thermal decomposition of tires: Yield: 98%

[0121]

[0122] 4.- Thermal decomposition of oxidized oil: Yield: 96%

[0123]

[0124] From the results of the actual experiments carried out, it can be concluded that the method and apparatus advantageously produce more carbon black than originally present in the starting material. Car and truck tires (which are the most carbon black-rich tires) have the following carbon black composition: Car tires have 13% to 17% carbon black, while truck tires have between 25% and 30% carbon black. These amounts Varies depending on manufacturer. Thus, on average, tires undergoing recycling have a carbon black content of 20%. It ca...

Abstract

The present invention relates to the recycling by depolymerisation through thermolysis. A method and installation for depolymerisation through efficient thermolysis for recycling is provided that allow the production of light hydrocarbons having high quality and being free of impurities and contaminants. This objective is achieved by methods and installations where either the secondary products of the process are re-fed to supply energy for the main recycling process or are refined to manufacture final usable and saleable products. Therefore, the use of the energy content of the starting materials is maximised by assuring their full utilisation, minimising the environmental harm while an energetically autonomous installation is provided. All the components of the waste or starting material may be recycled, by physico-chemical means, and no additional contaminant waste is produced.

Description

technical field [0001] The present invention relates generally to the field of recycling by depolymerization, and more particularly to the field of recycling by thermal decomposition that occurs by depolymerization, by refeeding part of the secondary product to vigorously replenish the depolymerization or by refining Part of the secondary products are obtained to obtain solid end products, liquid end products and gaseous end products suitable for consumption or sale, and the starting materials are fully recycled. Background technique [0002] The high consumption of products made of materials of organic origin, such as rubber, tires, plastics, etc., and the waste materials generated during the manufacturing process of such materials, pose great problems in terms of storage and destruction. In addition to the high costs involved, ecological and environmental consequences must also be considered. At the same time, some countries have encountered major problems in storing and ...
