Abstract (en)
[origin: DE19516379A1] According to the process described, old or waste plastics are depolymerized into a pumpable phase and a volatile phase to allow recovery of chemical raw materials and liquid fuel components. The volatile phase is separated into a gaseous phase and a condensate. In order to simplify the process in comparison with the state of the art, the depolymerised product remaining after the volatile phase is separated is also heated together with the condensate or condensate fractions in the presence of hydrogen under pressure and is subjected to hydrotreating, after non-boiling components are removed, to produce syncrude.
