Abstract:

Chemical recycling of waste plastics is one of the effective methods to deal with white pollution and realize high?value recycling synchronously. In particular, the technical route of further producing fuel oil or chemical products from waste plastic pyrolysis oil has attracted a great deal of attention. However, there are many impurities and complex components in plastics wastes, in which the effects of silicon and chlorine impurities on the reactor, products, catalysis and its own reactions cannot be ignored. This paper analyzed the sources, forms, formation mechanism and catalytic conversion laws of silicon and chlorine impurities in plastic pyrolysis oil, and put forward some effective countermeasures according to the possible adverse effects of impurities.

Key words: plastic waste, chemical recycling, silicon, chlorine
