摘要:

废旧塑料化学法回收是应对白色污染,同时实现高值化回收利用的有效方法之一,尤其是利用废塑料热解油进一步生产燃料油或化工产品的技术路线备受关注。但塑料垃圾杂质较多、成份复杂,其中杂质硅、氯对反应器、产物、催化剂或反应本身的影响均不可忽视。本文对塑料热解油中硅、氯杂质的来源、形态、生成机制及催化转化规律进行了分析,并根据杂质可能产生的不利影响提出了有效的应对策略。

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
