Abstract

At present, the disposal of polymer and rubber waste, and especially automobile tires, is one of the most acute environmental problems. These types of waste pollute the environment both when they are stored at landfills and during subsequent disposal, especially if it is carried out in the form of incineration. Therefore, at present, much attention is paid to thermal methods of their processing. The results of the study of liquid product of pyrolysis of tires of Kuznetskecology+ LLC are presented in the work. During its distillation, the following fractures were obtained (the yield wt% is indicated in parentheses): petroleum (4), gasoline (21), kerosene (18), diesel (47), fuel oil (10), for which the refractive index was determined and a conclusion about their chemical composition was drawn. When analyzing the data obtained during the analysis of liquid pyrolysis product and its fractions, as well as on the basis of published data, possible chemical reactions occurring during vulcanized rubber pyrolysis are proposed. Research results show that pyrolysis products are valuable chemical raw materials that have great prospects for industrial use, including the production of synthetic motor fuels.

Highlights

The production and consumption of products made from polymer and rubber materials is increasing every year
Having been worn; these products are stored and most often burnt. These processes are accompanied by significant environmental pollution, so the development of environmentally friendly technologies for rubber waste disposal is a very urgent task and attracts great attention of national and foreign scientists
To study the possibility of processing the liquid pyrolysis product, sampled at the enterprise, together with petroleum feeds, the temperature range of its distillation corresponding to the temperature range of oil distillation products were chosen

Summary

Introduction

The production and consumption of products made from polymer and rubber materials is increasing every year. These products are widely used including in the mining industry (conveyor belts, car tires, etc.). Having been worn; these products are stored and most often burnt. These processes are accompanied by significant environmental pollution, so the development of environmentally friendly technologies for rubber waste disposal is a very urgent task and attracts great attention of national and foreign scientists. The bulk of rubber waste is worn tread rubber. The total global production of tires being over 2 billion units per year; only 20-30% is recapped
