Abstract

The article shows the issues state of coal-mining enterprises carbonaceous wastes utilization, including by obtaining oil-sorbent. The characteristics of the feedstock are presented; experiment methods of obtaining a binder based on the livestock enterprises waste, of forming binder with filler (sawdust, coal waste); of pyrogenetic processing to obtain a sorbent are described. Possible options for the introduction of magnetite (a magnetic component) in the composition of the oil sorbent are considered: on the surface, in the volume of the granule and the magnetite core. In the course of the work it was found that the optimum content of coal dust in the sorbent granules is 75% by weight, and the most effective way of obtaining the magnetic sorbent is to apply the carbon material directly to the “core” of magnetite. However, in this case, the problem of finding an effective binder for magnetite arises. The option of applying magnetite on the surface of a carbon sorbent is not effective. Thus, at present, we use a mixture of coal waste, which binds to the uniform distribution of magnetite in the volume. The developed magnetic sorbents can be used in various weather conditions, including strong winds and icing of water bodies, as well as for small and medium currents.

Highlights

To date, one of the most large-scale sources of environmental pollution is mining, including coal – 92% of the total production of waste production according to 2015 [1]

Summary

Introduction

One of the most large-scale sources of environmental pollution is mining, including coal – 92% of the total production of waste production according to 2015 [1]. Oil is a complex of substances consisting of more than 3000 elements, most of which are oxidized, so oil has a rather large toxic effect on plants and living organisms Another important circumstance is the ability of oil, and especially its light fractions, to spread at high velocity along the water surface, forming a thin film of a large area [8, 9]. Because of this oil spills on the water are considered more dangerous than on the soil, where it is kept for some time by soil particles. The aim of the work is to develop a composition for obtaining magnetic oil sorbents by medium-temperature pyrolysis based on carbonaceous wastes from industrial enterprises, in particular coal mining waste and coal processing
