Abstract

Pyrolysis efficiency of used tyres and effect of temperature and pressure in subcritical/supercritical water were studied. Products were analyzed by GS-Mass, FTIR and elementary analyzer. Process of pyrolysis in supercritical /subcritical water was described and analyzed. It demonstrated that compared to subcritical condition, used tyres are decomposed much more completely in supercritical water and production of tar was prohibited. Content of C in solid residuals was high and could be recovered selectively. Inorganic atoms such as S and N dissolve in liquid in the form of inorganic salts.
