ABSTRACT:
The rapid increase in the use of plastic materials in the recent
years led to the accumulation of excessive amounts of plastic waste. The so-called
thermoplastics such as PE, PP, PS, PVC and PET as well as materials that are
derived from these are the type of plastic that is most used and consequently creates most of the waste. In this study, the original and waste forms of PE and PP
plastic types have been chosen for thermal and catalytic degradation. As
process parameter, 410oC - 450oC temperature interval and 600 mL/min constant flow rate
nitrogen gas have been chosen as the carrier gas and the reaction time was
considered to be 90 minutes for all experiments. Liquid products collected in experiments
were separated by means of fractioned distillation process. For purposes of
determining product distribution, the fractions, which were separated by
distillation, were diluted in an appropriate solution for analysis of GC/MS.
In the study conducted, it has been observed that the liquid product
distribution obtained mainly consists of a mixture of saturated and unsaturated
(heptane, heptane, octane, nonane, dodecane, etc.) hydrocarbons.
