    • The invention relates to a process for recycling waste which consists essentially of one or more plastics comprising polyvinyl chloride (PVC), in which: the waste is mixed with a heavy oil, in a reactor under an inert atmosphere, at an internal temperature of at least 300.degree. C., and the hydrogen chloride (HCl) which is evolved is collected; the contents of the reactor are then cracked at a temperature of at least 400.degree. C., and at least part of the gases which are evolved are extracted from the reactor; the contents of the reactor are then cooled and the residual solid product is collected. HCl, coke, hydrocarbon gases and various oils are thus mainly obtained.
    • 本发明涉及一种回收废物的方法,该方法主要由一种或多种包含聚氯乙烯(PVC)的塑料组成,其中:在惰性气氛下,在反应器内将废物与重油混合,在内部温度为 至少300℃,收集放出的氯化氢(HCl); 然后将反应器的内容物在至少400℃的温度下裂解,并且从反应器中提取至少部分放出的气体; 然后冷却反应器的内容物并收集残留的固体产物。 因此,主要获得HCl,焦炭,烃气体和各种油。
