Abstract: A method is described for the recovery of high yields of monomers from waste and scrape polymeric materials with minimal amounts of char and tar. The process involves heating the polymer at a heating rate of at least 500 DEG C./sec in a flow-through reactor. Heating is accomplished by contacting the polymer with a heat transfer material such as hot incandescent sand. A flow-through reactor is used to provide the high heating rates and short reactor residence times for the monomer product. The flow through reactor may be a circulating fluidized bed reactor, an entrainment reactor, a cyclonic reactor or a gravity reactor.

Abstract: A method is described for the recovery of high yields of monomers from waste and scrape polymeric materials with minimal amounts of char and tar. The process involves pyrolysis in a circulating fluid bed (CFB). The polymer is heated to a temperature of about 650 °C to about 1000 °C at a rate of more than 500 °C/sec in less than two seconds. Heat is supplied to the CFB by a stream of hot sand heated in a separate combustor. The sand is also used as the circulating fluid bed material of the CFB. The process is essentially devoid of solid carbon char and non-monomeric liquid products.
Abstract translation: 描述了一种从废物中回收高收率单体并用少量炭和焦油刮擦聚合物材料的方法。 该过程涉及循环流化床(CFB)中的热解。 聚合物在不到两秒的时间内以大于500℃/秒的速率加热到约650℃至约1000℃的温度。 通过在单独的燃烧室中加热的热砂流将热量供应给CFB。 砂也用作CFB的循环流化床材料。 该方法基本上没有固体碳焦和非单体液体产品。
