摘要：The present invention relates to a kind of methods and a kind of device, thethermal degradation for plastics. This plastics classification as classify polymerabf llenindustrial productions or from or from a recyclable rubbish ecological consideration bedecomposed into low molecular weight chemical recovery segment. Depolymerisiertthermal depolymerizations will be given in a reaktionsraum polymereinsatz
erfindungsgem, the wherein segment of volatility and low molecular weight, it obtainsdeducting from reaktionsraum, but the form of the fragment of these volatilehydrocarbon low molecular weights and part k ü rzerkettigen oligomer generates.Plastics can be crushed or particle or be suspended in heating and fusing. It is
preferentially above deducted in the gas reaktionsraum for the volatile compound thatthermal degradation generates. One advantage is in a wavy reaktionsraum sumpfphaseand aufkocher heater circuits. It climate warming and can be carried out at least partiallyin a vorbehandlungsbeh lter melting. This is by smashed particle or suspension polymermelt from one to reaktionsraum in vorbehandlungsbeh lter Mixed designs. Inreaktionsraum depolymerization..
