摘要:
Apparatus for decomposing a polyurethane resin and recovering the decomposed polyurethane resin as a polyamine compound and a polyol compound. The apparatus includes a first reactor that decomposes the polyurethane resin as the target compound of hydrolysis decomposition; a second reactor that hydrolyzes the decomposed target compound of decomposition with either one of supercritical water and high-temperature high-pressure water to a decomposition product mixture; a water supplier that feeds either one of supercritical water and high-temperature high-pressure water to the second reactor; and a post-processor that causes the decomposition product mixture discharged from the second reactor to be subjected to a post treatment procedure, such as dehydration, addition, distillation, separation, and liquid separation to recover the polyamine compound and the polyol compound.
