Thermal and thermo-catalytic conversion of waste polyolefins to fuel-like mixture of hydrocarbons

摘要

Results of the investigation of thermal degradation of polyolefins in the laboratory-scale set-upreactors are presented in the paper. Melting and cracking processes were carried out in two differenttypes of reactors at the temperature of 390-420°C. This article presents the results obtained forconversion of polyolefin waste in a reactor with a stirrer. Next, they were compared with the resultsobtained for the process carried out in a reactor with a molten metal bed, which was described in aprevious publication. For both processes, the final product consisted of a gaseous (2-16 % mass)and a liquid (84-98 % mass) part. No solid product was produced. The light, “gasoline” fraction ofthe liquid hydrocarbons mixture (C4-C10) made up over 50% of the liquid product. The overall(vapor) product may be used for electricity generation and the liquid product for fuel production.
