The pyrolysis of automobile tires was performed in a microwave electromagnetic field on an experimental microwave setup. The compositions of the obtained pyrolysis gas, liquid products, and a solid pyrolysis residue were determined. The experimental data showed that the products of pyrolysis are valuable chemical raw materials, and they can be successfully used in industry.

The article describes results of studies on the use of tall oil fatty acids (TOFA) when developing a method for producing esters to synthesize highly productive engine oil and additives. The article deals with the use of TOFA derivatives in the engine oil production industry. The process is efficient and safe for humans and the environment. Experiments on liquid TOFA esterification were conducted. As a catalyst, three types of ion exchange resins were used: Lewatit, Amberlite, and Tokem-100. Raw materials and reaction products were analyzed according to the federal standards for engine oils. Qualitative comparisons with Motul engine oil were carried out. The main research problems, tasks and methods were formulated.
