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.
