Criteria for the Selection of Synthetic Polymeric Waste as a Raw Material for Producing Carbon Sorbents with Predetermined Properties

The results of studies on the thermal processing of synthetic multi-tonnage polymeric waste (polypropylene, polycarbonate, textolite, PET, organoplastics and tire rubber) with the production of carbon sorbents for technological and environmental purposes are presented. The influence of the nature of the activating agent and the conditions of the process with the production of sorbents with predetermined properties was studied. Analysis of the research results allowed us to establish that the main factors affecting the yield of carbonizate and the formation of a porous structure of carbon sorbents from synthetic polymer waste are the degree of aromaticity and the location of benzene rings in the polymer structure, the proportion of oxygen in the precursor. The criteria for selecting synthetic polymer wastes as raw materials for obtaining carbon sorbents with predetermined properties are established. The results of the research can be used in the development of technologies for obtaining carbon sorbents with predetermined properties from waste synthetic polymers and the selection of technological parameters for processes.
