Fast Pyrolysis of Tetra Pak and Thermal Analysis of Its Components

Abstract

Research of the thermal decomposition of Tetra Pak had been done. Thermal analysis of Tetra Pak, cardboard and polyethylene had been done. TG data showed that thermal decomposition of Tetra Pak occurred in three stages: drying and melting of polyethylene occurred at the first stage, at the second stage thermal decomposition of cardboard happened; in the third stage decomposition of polyethylene took place. Fast pyrolysis laboratory scale setup had been done. Experiments on Tetra Pak pyrolysis had been done at temperatures 250, 450 and 650 °C. During the fast pyrolysis of Tetra Pak we can have 30 % liquid products and 45 % solid products which can be used in different applications. Gas chromatography-mass spectrometry of fast pyrolysis liquid products samples had been done.
