摘要：
A method of recovering pyrolysis products of resin of the present invention includes cooling gaseous pyrolysis products generated from pyrolysis of the resin in a pyrolysis tank to recover the resin as liquid pyrolysis products. The method includes the following steps (1) to (4): (1) continuously feeding fluidization gas, heated solid particles, and a resin into the pyrolysis tank to fluidize the solid particles and the resin by the fluidization gas; (2) continuously feeding the resin into the pyrolysis tank from a position which is ½ or less of the height of a solid particle layer in the pyrolysis tank in a stationary state; (3) continuously discharging the solid particles from a position lower than the height of a feeding position of the resin; and (4) heating the discharged solid particles in a heating furnace and then feeding the heated solid particles into the pyrolysis tank.
摘要（中）：
回收本发明树脂热解产物的方法包括冷却由热解槽中的树脂热分解产生的气态热解产物，以回收作为液体热解产物的树脂。 该方法包括以下步骤（1）至（4）：（1）将流化气体，加热的固体颗粒和树脂连续供入热解槽中，以使流化气体使固体颗粒和树脂流态化; （2）从处于静止状态的热解槽中的固体颗粒层的高度的1/2以下的位置将树脂连续进料到热解槽中; （3）从低于树脂供给位置的高度的位置连续排出固体颗粒; 和（4）在加热炉中加热排出的固体颗粒，然后将加热的固体颗粒进料到热解槽中。
